azbil Yamatake Memorial–Overview of Exhibition Contents

Yamatake Memorial–Overview of Exhibition Contents The life of the company’s founder, Takehiko Yamaguchi, who lived through Japan’s Meiji, Taisho, and Showa eras, and his innovative ideas and skills are chronicled along with the history of Japanese industry.

A man who did not give up on his dream of becoming an entrepreneur
Before Yamatake Shokai’s founding (biography of takehiko yamaguchi)

In 1884, at the age of 16, Takehiko left Kagoshima for Tokyo to live with his brother-in-law
Kiyosuke Oku, who was...


Takehiko in his boyhood.


Takehiko was born in the castle town of Kagoshima (on the island of Kyushu) on July 2.

Kiyosuke Oku, Director of the Fisheries Bureau, Ministry of Agriculture and Commerce (Takehiko’s brother-in-law)


At the age of 16 he left Kagoshima for Tokyo to live with his brother-in-law Kiyosuke Oku, who was working for the Ministry of Agriculture and Commerce. Takehiko made preparations for higher education while doing Oku’s household chores.


Takehiko entered the Tokyo Vocational School (presently, Tokyo Institute of Technology) to learn machine engineering.

Yasuda Zaibatsu founder Zenjiro Yasuda (Meiji era)

Korekiyo Takahashi as Minister of Agriculture and Commerce


After graduation, Takehiko began working in the same place as his brother-in-law, in the Ministry of Agriculture and Commerce, as an assistant patent examiner. This is when he first met Korekiyo Takahashi, who would later become Prime Minister. Takehiko was introduced by Oku to Takahashi, who was a close friend of Oku and the first Minister of Agriculture and Commerce at the time.
When Takahashi was asked by Zenjiro Yasuda, the founder of Yasuda Zaibatsu, for the right person to dispatch to developed countries to bring back the knowledge and technology necessary for domestic nail production, Takahashi recommended Takehiko.


With the support of Yasuda, Takehiko traveled to Cleveland in the United States and immersed himself for one year in the study of machines for nail manufacturing. He also visited Germany to observe machine tools in an advanced nation.


Having amassed knowledge about developed nations’ technology, Takehiko returned to Japan at Yasuda’s request, and worked in various positions, such as financial manager of a railroad in Hokkaido, general manager of a shipbuilding company, etc.


Since he dreamed of being an entrepreneur, Takehiko returned to Tokyo to establish Yamatake Shokai Co., Ltd. Firmly believing that importing good machine tools from developed nations was essential to industrial development in Japan, Takehiko obtained distribution rights one after another from about 50 companies in the U.S. and Europe.


Because of a need for domestic production of oxygen, which is necessary for welding, Takehiko founded Nippon Sanso Limited Partnership Company (presently, Taiyo Nippon Sanso Corporation).


Takehiko founded Nippon Seiko Limited Partnership Company (presently, NSK Ltd.), which provided accurate machining using the machine tools that Takehiko imported.


Contributions to Japanese industry by improving quality and safety
1906 - 1942
On the road to becoming an industrial instrumentation manufacture

On December 1, 1906, Yamatake Shokai opened in Tokyo. This date is now observed as...


Original location of Yamatake Shokai


On December 1, Yamatake Shokai opened in Kyobashi, Tokyo City (presently, Yaesu, Chuo-ku, Tokyo). This date is now observed as the anniversary of the azbil Group’s founding.


Starting with a branch office in Osaka, the company gradually expanded its sales network, moving later into Nagoya, Fukuoka, Yokosuka, and Kure.


After the First World War began and the British Army sealed off the Mediterranean Sea, it became extremely difficult for cargo from Germany to reach Japan. Yamatake Shokai, which was relying on machinery from Germany, was faced with a challenge.
Takehiko, deciding that importing from Europe was becoming too difficult, resolved to seek import channels from the U.S., a newly industrialized nation.

A Yamatake Vignette

Early in the Taisho period, furnace temperature was not yet measurable, and artisans needed to judge the temperature of iron in the furnace by looking at changes in the red color based on their experience and intuition. Ensuring reliable product quality was difficult too. It was under these circumstances that Takehiko introduced millivoltometers and pyrometers equipped with platinum thermocouples into Japan, which contributed to the quality and safety of Japanese industry.

President Richard Brown


Takehiko traveled to the U.S. in October to visit local manufacturers. The visit paid off with Yamatake Shokai signing an agreement to act as the sole Japanese distributor for the Brown Instrument Company. The sale of imports from Brown began in 1920.

Brown Instrument Company


The Great Depression began on October 24th. Prices on the New York Stock Exchange fell precipitously, and Yamatake Shokai was faced with the greatest crisis since its founding.


Yamatake Shokai began assembling Brown’s industrial instruments. The main components of instruments were imported from Brown, while minor parts were of domestic manufacture, gathered from inside and outside of Yamatake Shokai.

A Yamatake Vignette

The first products assembled by Yamatake:
 Pyrometers for Toyo Babcock 1,683 yen
 Pyrometers for Sumitomo Metal Industries, Ltd. 1,500 yen
 Controllers for Osaka Industrial Laboratory 2,950 yen
At this time the price of a bag of rice (approx. 60 kg) was slightly over 8 yen.

Yamatake Shokai Instrument Manufacturing Plant (Ohmori, Tokyo)


A factory called Yamatake Shokai Instrument Manufacturing Plant was constructed in Ohmori, Tokyo. At this point, Yamatake Shokai transformed itself from a machine tool import trader to an industrial instrument manufacturer.

The first finished products assembled at Yamatake Shokai Instrument Manufacturing Plant using Brown’s components (1935)


The Kamata Factory was constructed. Also, a company called Nihon Brown Keiki Co., Ltd., which was relatively small business at the time, was established specifically for instruments. Takehiko’s second son, Toshihiko, assumed office as its president. The name of the company was changed to Yamatake Keiki Co., Ltd., due to a wave of war-time sentiment in Japan during the Second World War.


On April 1, Yamatake Shokai changed its name to Yamatake Kogyo Co., Ltd. (kogyo = “manufacturing”, shokai = “trading company”) to meet the war-time rule that “trading companies must not be involved in manufacturing.” On April 27, the commercial department of Yamatake Kogyo separated to make an independent company called Yamatake Shokai Co., Ltd.
Yamatake Kogyo Co., Ltd., then absorbed Yamatake Keiki to make a new Yamatake Kogyo Co., Ltd. Takehiko became its president and Toshihiko its vice president.


Using resourcefulness to introduce new technologies into Japan
1936 - 1953
Business expansion from instrumentation to control devices

In 1936, Takehiko, after studying foreign-made valves, successfully produced Japan’s first
top-and-bottom-guided double-seated control valve and...


Double-Seated Control Valve


Takehiko, after studying foreign-made valves, successfully produced Japan’s first top-and-bottom-guided double-seated control valve and delivered it to Nippon Oil refinery in Akita. In the same year, the February 26 Incident (an attempted coup d’état in Japan) took place.


With the start of the Pacific War, the import of machines from the U.S. was banned. Yamatake shipped many industrial instruments to refineries, since the army and navy were planning new refineries at more than ten locations, and Nihon Sekiyu Co., Ltd., Showa Sekiyu Co., Ltd., and Maruzen Sekiyu Co., Ltd., were expanding their facilities one after another to meet increasing demand for petrochemical refining.


The war ended. The aftermath of the war was difficult and there was almost no demand for machine tools or industrial instruments. The company changed its articles of association and started to make general-purpose electrical devices in order to pay its employees.

A Yamatake Vignette

Yamatake deposited patent fees to be paid to Brown Instrument Co., but after the war started they could not be transferred to the U.S., which was Japan’s wartime enemy. Toshihiko was determined to make payment, however, as he believed that debtor-creditor relationships between individuals should not be affected by the war, so he continued making deposits. When the war ended, he paid the entire debt of 247,355.51 yen to the Brown Instrument Co. This greatly impressed members of the American General Headquarters, because there was no other example of a company that continued depositing patent fees during the war in order to pay a company in an enemy nation. This act of good faith was a factor in the later establishment of the partnership with Honeywell.

Racking their brains and using the scarce materials available, Yamatake’s employees made electrical equipment, such as steamed rice warmers, foot-warmers, heaters, agricultural sprayers, etc.

Steamed Rice Warmer and Foot-warmer Displayed in Yamatake Memorial


A priority production system focusing on coal and iron & steel was adopted as Japanese economic policy. To meet the increased demand for industrial instrumentation, Yamatake began producing flow recorder-calculators and differential pressure transmitters as well as thermometers, pressure meters, carbon dioxide meters, etc.


A technology information magazine called Yamatake Times, the publication of which was suspended during the war, was once again issued. The magazine presented the current situation in important industries in the U.S., where many instruments were being used in highly efficient production management systems.

A Yamatake Vignette

“Instrumentation,” a word found in U.S. materials at the time, was a new word for Japanese industries and there was no existing Japanese translation. It is believed that Japanese keiso was adopted for “instrumentation” based on the idea of a Tokyo University Professor, Zenzaburo Sawai.

President Toshihiko Yamaguchi (left) leaving for the U.S. for negotiation with Honeywell


President Toshihiko Yamaguchi traveled to the U.S. and successfully concluded a technological partnership agreement with Honeywell, which had acquired the Brown Instrument Company. Since Honeywell dealt not only in industrial instruments but also in air conditioning devices, combustion control devices, and microswitches, these products and their technologies were introduced to Japan for the first time.
In the same year, a peace treaty between Japan and the Allied powers was signed in San Francisco.


Yamatake doubled its capital, which was 12 million yen at the time, the increase coming from Honeywell when the companies formed an equity-based alliance, the first with a foreign company in Japanese postwar history.

A Yamatake Vignette

At first, Honeywell proposed to supply 51 % of the capital, but Toshihiko insisted on a 50-50 arrangement on the grounds that joint management and working together through thick and thin required a fifty-fifty relationship between the parties. Honeywell agreed with 50 % share at last, but obtaining permission from the Japanese Ministry of International Trade and Industry and Finance Ministry proved to be difficult, since it was a common understanding in Japan that 49 % was the maximum amount of foreign capital allowed, in order to protect Japanese companies, whose foundations were still weak after the war, from being taken over. Toshihiko visited relevant ministries every day to tell them about his long and reliable relationships with Honeywell, starting in the pre-war period, and finally obtained official permission.


Embarking on a new journey as an automation equipment manufacturer
1952 - 1971
Partnership with Honeywell

On April 1, 1952, the partnership between Yamatake and Honeywell received official
permission. Before any other Japanese company, Yamatake...


Instrumentation, Honeywell’s magazine on
instrumentation technologies


On April 1, the technological partnership agreement between Yamatake and Honeywell received official permission. Before any other Japanese company, Yamatake established a partnership with a foreign company and started business as a comprehensive manufacturer of automation equipment.
The company conveyed the up-to-date information from Honeywell to customers in Japan and greatly contributed to promoting public awareness of process instrumentation.

50-year ceremony held at Meguro Kokaido


On the 50th anniversary of the founding of Yamatake, the company changed its name from Yamatake Keiki Co., Ltd., to Yamatake Honeywell Keiki Co., Ltd., in order to deepen the partnership with Honeywell.

The company’s business was divided into the four areas of microswitches, industrial instruments, control valves, and control devices.
The Kamata Factory manufactured Modutrol motors, the first compact motors for control devices in Japan.

Fujisawa Factory building


The Fujisawa Factory started operation in May.
The company’s founder, Takehiko Yamaguchi, received the Medal with Blue Ribbon, a Medal of Honor awarded by the Japanese Government.


Takehiko Yamaguchi died on April 11, at the age of 93, at his home in Kamakura. Takehiko lived to see his son and successor, Toshihiko, overcome many difficulties after the war and expand the company in association with the partner company of Honeywell.

Yamatake Honeywell Keiki Co., Ltd., established a wholly-owned company called Yamatake Keiso Co., Ltd., to provide services such as air conditioning instrumentation, engineering, maintenance, and sale of control devices.

A Yamatake Vignette

It was epoch-making that a manufacturer like Yamatake Honeywell Keiso had a construction department as a separate company at that time. This Yamatake Keiso would later become Yamatake Building Systems Co., Ltd.

Yamatake Maintenance headquarters (Fukuoka)


Yamatake Maintenance Co., Ltd. was established on September 27 in Fukuoka.

A Yamatake Vignette

Yamatake Maintenance Co. provided services in Western Japan related to the industrial instruments made by Yamatake-Honeywell, eventually expanding its operations across Japan. The company developed into Yamatake Engineering Service Co., then Yamatake Engineering Co., Ltd., and finally Yamatake Sangyo System Co., Ltd.


On the 60th anniversary of its founding, the company changed its name from Yamatake-Honeywell Keiso Co., Ltd, to Yamatake-Honeywell Co., Ltd.

Sweatt Engineer-Scientist Award

Honeywell Honorary President Harold W. Sweatt


For the development of the CurrentroniK, Shinichiro Ogawa of Yamatake-Honeywell received the H. W. Sweatt Award, the first non-U.S. citizen to do so.

A Yamatake Vignette

Honeywell instituted the H.W. Sweatt Award in 1965 to recognize top scientists for creativity and achievements in technological development. The award was named after the company’s honorary president, Harold W. Sweatt. The award is highly respected in the U.S. and made on an extremely selective basis. Since 1968, when Ogawa received the award, many winners have been selected from Yamatake.


Yamatake-Honeywell was listed in the First Section of the Tokyo Stock Exchange on February 1.


Five Yamatake developers and engineers were dispatched to Honeywell’s Ft. Washington Factory on the outskirts of Philadelphia to take part in the TDCS2000/3000 joint development project.


A great transformation in instrumentation, from analog to digital
1960s - 2000s
Industrial automation

In 1961, Yamatake began to manufacture Honeywell’s ETOS electrical analog instruments.
A group of ETOS sensors, such as electrical pressure transmitters, differential pressure transmitters,
temperature converters, and air pressure converters, were...


'60s The golden age of electrical analog instrumentation—high-density panel instrumentation and instrument control

ETOS recorder/controller


Yamatake began to manufacture Honeywell’s ETOS electrical analog instruments. A group of ETOS sensors, such as electrical pressure transmitters, differential pressure transmitters, temperature converters, and air pressure converters, were also manufactured in Japan. ETOS sensors were distinctive because of their 4–10 mA two-line signal transmission method and incorporation of transistors in all the functions to deliver fast and accurate responses. The concepts used in its development were so significant that they became standard in electrical instruments that followed.

Cage-guided control valve (left) and low-noise control valve (right)


Yamatake began to market cage-guided control valves whose architecture was a world first, and very different from that of existing top-and-bottom guided control valves. Since this cage-guided valve was easy to use and of highly reliable quality with low noise, it became a huge hit.
In the 1970s, the rate of internal production reached 90 % of the total production and Yamatake’s control valve business ranked first among domestic manufacturers. It was recognized as a comprehensive instrument manufacturer who could supply everything from sensors to actuators.

VSI (vertical
scale indicating


While considering how compact instruments should be designed in the new age of instrumentation, Yamatake chose to meet the need for space-saving, small instruments that could be easily monitored by operators, and it developed the VSI vertical scale indicating controller with new current-balancing circuits.
The PVSI pneumatic vertical scale indicating controller was displayed as a model product at the annual Measurement and Control Fair, and two years later in 1967, the N-matik series of pneumatic vertical scale indicating controllers was introduced. Its front panel measured only 2×6 inches, the smallest in the world at the time.

'70s A revolutionary shift from analog to digital instrumentation—the age of “saving” in pursuit of efficiency

TDCS2000 total distributed control system


The TDCS2000 total distributed control system, which is considered to be one of the largest technological innovations in the history of industrial instrumentation, was introduced. In addition to existing analog instruments’ PID control function, the TDCS2000 was equipped with advanced control, including high-performance calculating and sequence control functions, so it was able to meet various needs for functions such as batch process control as well as existing continuous control.
The age of digital instrumentation had come, and these products began to be introduced to advanced users like steel and iron plants and petrochemical refineries.

MagneW-M series electromagnetic flowmeters for general ducts

Highly rated limit switches


As environmental problems like water pollution increasingly came to light, Yamatake began selling MagneW electromagnetic flowmeters, which used a rectangular wave excitation method, and which attracted attention as a revolutionary flowmeter causing no pressure loss. In the 1980s, MagneW 3000Plus was selected for use by the Australian Alcoa company, the top alumina refining company in the world, a first step in the product’s global distribution.
Yamatake’s limit switches, which contribute to safety instrumentation, began to be highly evaluated around this time.

'80s Development of the DCS—productivity-boosting digital technologies



The TDCS3000LCN was announced to the world at the annual Measurement and Control Fair. This product was developed by the “Project 80” team, which was organized in the 1980s to work with Honeywell and develop a successor device to the TDCS2000.

SFC (smart field communicator) and DSTJ3000


The DSTJ3000 smart transmitter went on the market. Together with the TDCS3000, the product was used by many petrochemical plants and chemical plants.



The DigitroniK SDC200 temperature indicating controller was introduced, laying the foundation for current temperature controllers. It sold so many units that production could not keep up.

'90s The dawning of the Information Age and networked instrumentation systems

SGC3000 smart gas chronograph


The SGC3000 smart gas chronograph, developed entirely with the company’s own technologies, including semiconductor sensor components, made its debut. It was made compact and lightweight so that it could be installed in the plant like a general transmitter, which helped to improve responsiveness, reducing installation and operation costs.
This product changed the image of existing chronographs for processed gas, as it was based on an entirely new concept, enabling users to handle it like a transmitter.



The Harmonas automation system, providing highly reliable communication and control with redundancy using duplicate hardware, became available.


SVP3000 smart valve positioner

Compact control valve (CV3000 Alpha Plus Series)


In response to Great Hanshin earthquake in January, the Japanese government instructed gas companies across Japan to equip their facilities with gas shutoff equipment that would automatically stop gas supply with shutoff valves activated by seismometers. Yamatake worked with Tokyo Gas to develop the intelligent SES60 seismometer in order to prevent secondary disasters due to gas leakage after an earthquake. Tokyo Gas and other gas companies began incorporating the device into disaster prevention systems at their facilities.
In the 1990s, the compact CV3000 Alpha Plus series of control valves, designed for work in densely piped industrial areas, such as fine chemical manufacturing, were developed and marketed, followed by the development of SVP3000 smart valve positioners, with a built-in microprocessor. These products had functions, such as online control of actuator range, and transmission of analytical data and valve position, which began the era of advanced functionality.

'00s Networked open systems—optimal production control—contributions to society

HGC303 Heat Value Gas Chromatograph


In response to natural gas trading based on calorific value, which began in the EU, the company announced the world’s smallest gas chromatograph, the HGC303, which was increasingly purchased by power plants and LNG carriers as its convenience was recognized.

STEAMcube steam flowmeter

AIRcube air flowmeter


Low-temperature valves and AIRcube air flowmeters, which incorporated a multifunctional semiconductor differential pressure/pressure/temperature sensor, were introduced. In the following year, 2004, many devices, such as STEAMcube steam flowmeters, were introduced for energy management.
In the 2000s, the Industrial-DEO production control system was developed using an open architecture approach, which enabled the system to communicate with devices of different types and also with peripheral devices, whose technologies continually change.
System innovation continued to progress in the field, including improvement and optimum control of production, quality control, and energy and environmental management, and automation began contributing to society as a whole, including industry.


A building management system for 24-hour year-round operation
1960s - 2000s
Building automation

Around 1964, with the spread of computers and increased load from lighting, more and more buildings
began to need an air conditioning system even in the winter, and ...


'60s Early years of building automation


With the spread of computers and increased load from lighting, more and more buildings began to need an air conditioning system even in the winter, and they also began operating 24/7/365. Against this background, control devices and building management systems began playing an increasingly important role in meeting the complex and diverse needs for building air conditioning systems.
For example, the NHK Broadcast Center had to operate continuously in order to manage around-the-clock broadcasting, and the Sony Building needed to air-condition the building in order to provide both its lighting equipment and visitors with cool air.


After the construction of Japan’s first skyscraper, the Kasumigaseki Building, there was a flurry of construction of super-high buildings, and urban areas were increasingly filled with high buildings. During the construction of high-rise-buildings in areas surrounding Shinjuku-ku, Tokyo, which is a symbol of the age of skyscrapers, many Yamatake products were used.

System 6J


The System 6J central monitoring system was developed with a standardized central monitoring panel. Previously, central monitoring panels had been designed separately for each building. Since building facilities differ from building to building, it was believed to be impossible to standardize the central monitoring system. However, by standardizing the process of determining the specifications, trial runs, and service after delivery, Yamatake succeeded in spreading the product across Japan.

'70s A 2nd-generation building automation solution: DELTA

Room thermostat

In the 1970s, air conditioners were no longer a luxury in Japan; not only office buildings and department stores, but also small cafés in towns and recreational arcades were fully equipped with air conditioning systems. The room thermostat on the right played a role in popularizing air conditioners in Japan.

DELTA 2000


A new DELTA 2000 imported from Honeywell went on the market. Large and very high buildings were constructed on spacious grounds, and therefore their facilities became ever more complex. This led to a strong demand for centralized control of the facilities. To meet this need the DELTA 2000 was introduced as a central monitoring system that could provide integrated management of multiple buildings scattered around a region as well as large buildings like high-rises, and also could comprehensively manage the building’s air conditioning, electricity, sanitation, fire and burglar alarm, etc., facilities. The system had the extraordinary ability to control more than 20,000 items.

DELTA 2000, 500 Series (front)
and 1000 Series (back)


Since the DELTA 2000 proved to be too expensive to sell in Japan, Yamatake considered domestic production of the system for small-sized and middle-sized buildings. It began developing the 500 series of DELTA 2000 (the DELTA 500), and announced the product’s availability in the same year.
As a result of oil crises in Japan in 1973 and 1979, the Japanese economy became sluggish, and public sentiment increased for energy efficiency in building air conditioning. The DELTA 500 was able to take advantage of this trend, since its recently developed microcomputers were capable of energy-saving control.

'80s A 3rd-generation BA solution: the SAVIC energy-saving management system


Yamatake on its own developed the SAVIC 200/500/800 building management system. The DELTA 2000 series, introduced from Honeywell, did not work well in Japan not only because of its price, but also because its specifications did not meet Japanese customers’ needs. Its greatest disadvantage was that it could not display text in the Japanese language. Consequently Yamatake developed the SAVIC 200/500/800, which could display lists in Japanese kana characters on CRT monitors.


The SAVIC-EC system for small-sized building management, which could control 100 items, was developed. The system communicated with control points at sites that were directly connected to the main EC unit. It had basic BA functions and energy-saving applications as well.

The SAVIC series and air conditioning control devices

SAVIC 1000

SAVIC 2000


The SAVIC 1000 and 2000 systems for large-scale building management, which could control 1000 and 2000 items respectively, were developed with basic BA functions and energy-saving applications. The systems’ human-machine interface was capable of displaying text in Japanese kanji characters on CRT monitors.

The PARAMATRIX- II, developed in 1984, is
on display in Yamatake Memorial


The PARAMATRIX-II was developed. First-generation PARAMATRIX heat source controllers were developed in the 1970s. In Japan, which has four distinct seasons, replacing heat-source devices and changing the number of heat-source devices according to the changing seasons were important duties of building facility managers. Yamatake developed the unique PARAMATRIX-II, which could control heat sources flexibly.
The PARAMATRIX-II became a byword for heat source controller in the air-conditioning industry. After the PARAMATRIX-II, Yamatake continued developing successors, including the PARAMATRIX-III in 1998 and PARAMATRIX 4 in 2011.

BOSS Center


In October, the BOSS* Center, a remote monitoring building management service, was established in Tokyo. Demand for its services gradually increased, and in the following year, 1985, another BOSS Center started operations in Osaka.
*BOSS: building operation support service

savic-net 50

savic-net 20


The savic-net 50 and 20 series were developed. Previous models had mainly operated air-conditioning facilities, but the system was now capable of integrated management of security, disaster prevention, lighting, etc., facilities in addition to air conditioning. Furthermore, it could work with information and telecommunication networks, and therefore could provide audio warning to system managers via a company’s PBX telephone system.

'90s A 4th-generation building automation solution: the integrated BMS

In the 1990s, the concept of an ecologically friendly city that is viable for future generations, called an “eco-city,” became increasingly popular. Instead of constructing many buildings with no plan, governments and people began discussing better urban development, including landscape conservation in cities and traffic planning.
The 1990s saw a transition from the mindset of constructing buildings haphazardly to urban planning, the typical examples in Japan being Roppongi Hills, Yokohama MM21, and Chiba Makuhari New City, all of which were specific areas redeveloped as a city within a city.

BESTMAN maintenance service


A maintenance service called BESTMAN went on the market, the name being an acronym for “building environment system technical management.” The system was based on the idea of preventive maintenance, in which devices are maintained based on anticipation of problems instead of being repaired after problems were found. It is a functionally systematized group of services including maintenance, guarantees, and parts management.


In October, Yamatake began providing energy service company (ESCO) services. In order to strategically address customers’ challenges, such as cost reduction, environmental preservation, and stable operation of facilities, Yamatake began offering temsTM (a total energy management service) to provide best solutions tailored to customers’ needs, including operational support for optimal management of building facilities, assessment, suggestion of plans for improvement, energy-saving renovations, and even procurement of various types of energy.

Critical environment control system


Yamatake began business in the area of critical environments, where high-quality treatment of air is vital and ventilation is the main concern of customers, such as chemical research facilities, animal rearing facilities, bioscience labs, and hospitals facing the risk of infections.

'00s Networked system for building automation


In 2002, Honeywell sold all its shares to Yamatake, and Yamatake began business development on its own. By way of business development measures, Yamatake decided to reduce costs with production sites in China, while developing and marketing high value-added products.
A compact and lightweight device with valve and actuator functions was developed and sold beginning in the mid-1980s in Japan, and production was launched in China in the 2000s by Dalian Yamatake Control Instruments Co., Ltd.

savic-net™ FX


The next-generation savic-net™ FX building management system was placed on the market. Yamatake offered customers a superior system based on its key capabilities of monitoring buildings regardless of place and time, selecting any monitor station type, and selecting functions regardless of building size.

Intelligent Component Series


Yamatake developed the Intelligent Component Series of control devices, which could handle an increased amount of data with more sophisticated basic measurement and control functions. The origin of the name was the ability of these components to retain device data and control data and to adapt their behavior according to the environment.
