TATSUMI RYOKI HISTORY
Our company has a proven track record all over japan as the developer and manufacturer of “dry load banks”. In recent years, we have answered societal needs for environment-friendly technology with “high efficiency solar water heaters” and “small wind power generator,” which we have commercialized, and conduct all steps from manufacturing to installation with in-house capability. Below, we will introduce our past efforts.
|April, 1964||The father of current president Toyoshi Kondo founded the company “Kondo Kogyo” as a family business. He worked on processing of joint iron plates during bridge construction.|
|October, 1969||Expanded business as a partner company of Ishikawajima Shipbuilding Chemical Machines.|
Constructed our company factory at 3 Higashisuna, Koto, Tokyo
In addition to bridge construction, expanded business to installation work for power generation equipment and construction work for electrical equipment.
|March 2nd, 1974||Become a Corporation from a family buisiness, and changed our name to “Tatsumi Ryoki, Co. Ltd.”|
|June 1st, 1974||
The Fire Service Act was amended, and installation of emergency power generation facilities became mandatory for buildings above a certain size, which resulted in booming of power generation equipment installation all over Japan.
Tatsumi Ryoki receives an influx of orders for the installation of power generation facilities (e.g., residential generators on the rooftop of the 10th floor of the Akihabara Electric Building.
Seeing the installation of power generation facilities for disaster preparedness as an opportunity for creating a new market, the company has shifted its focus area from conventional bridge construction business to form a new business model on new power generation facilities installation business.
|June, 1979||With the significant increase in orders for installation work, we moved our headquarters office and main plant to 6 Higashisuna, Koto, Tokyo. Headquarters|

|August, 1992||Constructed our production base at Togane depo(1,200㎡) in 3429-1 Matsunogo, Togane, Chiba. Chiba Office|
|September, 1995||President Toyoshi Kondo comes up with the idea of creating “test inspection equipment (load resistors) which do not use water at all, so that there is no risk of electrical shock or electrical leakage.” Based on this idea, and as a result of trial and error, we developed a “dry load bank”. This uses a fin heater, which is an electrothermal body with heat dissipating fins wrapped around the resistance surface of an electrically conductive resistance body. This was commercialized, and the first unit was delivered to a generator manufacturer.|
|April, 1996||Expanded the Chiba Office.|
|November, 2000||Constructed the Tokyo office (1,204㎡) in7-16-12 Higashisuna, Koto, Tokyo, to handle small rental products. Tokyo Office|

|March 21th, 2011||As the emergency generator at the Hirosegawa River purification plant in Sendai, Miyagi was sunk in a flooded because of Tsunami, and our 6kV/1000kVA is used as a temporary power source.|
|September, 2011||Began Research & Development (R&D) activity on windmills, and installed one at the roof of our office building.|
|June, 2013||Installed, as a CHAdeMO member, instantaneous power charging equipment at the Tokyo office.|
|October, 2013||Entered into the “Agreement on power supply in the event of a disaster” with Koto Ward, Tokyo.|
