Introduction of Kashima Plant


Kashima Plant is located in Hasaki Industrial Park in Kamisu-shi, Ibaraki Prefecture.
There is a company specializing in utility supply, meaning electricity, stream and demineralized water are available without having any dedicated facilities. Also, industrial plankton net with high supply ability is available which is ideal for chemical plants. As for the wastewater treatment, there is a public wastewater treatment plant which can handle all the wastewater from this industrial area.

Introduction of P&D Center

Site Area:

About 7,400㎡

Total Floor Area:

About 4,000㎡


In 1961, we have secured plant site in Fujimimura (currently Fujimi-shi), Iruma-gun, Saitama-Prefecture through the good offices of Tokyo Bureau of Economy, Trade and Industry and Industrial Development Promotion Headquarter of Saitama-Prefecture. In the following year of 1962 construction of Shiki Plant was completed, and production started immediately. In those days this area was typical rural area with only few houses around. Chorus of frogs frequently annoyed people in summer, and people enjoyed fishing by the river at the back of the plant

Nowadays, the surrounding environment has changed dramatically as a bed-town for people working in Tokyo. Since the plant is surrounded by many houses and also because of the new regulations set, it was getting difficult to run the plant as a chemical plant.
Accordingly we have changed the plant to a compact plant for small-scale and variety production for new products, prototypes, sample products etc - and it was renamed as P&D Center in December 2010.

Features of P&D Center:

It is a pilot plant handling small amount production and variety production focusing on new products, prototypes and sample products.
It is located in south of Saitama-Prefecture, with a good access to central Tokyo. It serves as a center of delivery within Kanto Area, and it has worked as an alternate production plant at the time of disaster.
