Choshu Industry was established in 1980 as a water heater manufacturer.
At the time of the establishment, our founder said in his greetings, "We want to enrich the lives of the
Japanese people, who love taking baths, so that they can enjoy ample hot water to their heart’s content."
We strive for better future being considerate of people’s lives with the founder’s words in mind.
The products of Choshu Industry are composed of high-performance and reliable parts and
materials.
In our production lines, we repeatedly conduct thorough inspections with devices and human eyes, thus ensuring
high quality.
Our commitment to quality and production in Japan is the pride and mission of Choshu Industry.
The first mega solar power plant of a major electric company in Chugoku region of Japan adopted Choshu
Industry’s solar cell modules.
For more than 20 years, we have accumulated an extensive track record in solar power generation for both
residential use and industrial use.
We are conducting module tests under various weather conditions to ensure high durability.
We have created rigorous testing criteria independently as part of our commitment to improving durability for long-term use.
We conduct the test with 1.5 times of the design load.
Power storage systems have been attracting attention recently for power utilization
efficiency and disaster preparation.
We are developing advanced power storage systems independently by taking advantage of the expertise that we have
cultivated in solar power generation to date.
We have market shares in a wide range of fields in the industry as one of the few manufacturers with advanced
technologies in both solar power generation and power storage systems.
