I would like to introduce an invention closely related to today, August 10. The invention is the “Takuma-style boiler” invented by Tsunekichi Takuma (1872.2.8~1953.12.22), a Meiji-era born industrialist, inventor, and founder of Takuma Corporation.

It is said that Tsunekichi Takuma applied for a patent for the Takuma boiler, Japan’s first domestically produced boiler, to the Patent Office, a foreign bureau of the Ministry of Agriculture and Commerce at the time, 107 years ago (1915) today. Some sources say that he invented the boiler in 1912 and patented it the following year.
Tsunekichi Takuma was a successful lumber merchant in his thirties, but after investing in a boiler manufacturing business, he failed and incurred a large amount of debt. However, he later went on to develop boilers on his own and completed the Takuma-style boiler. This was so successful that it put a stop to the import of foreign-made boilers.

In 1936, Tsunekichi Takuma established the Takuma Tsunekichi Research Institute at his home (now Takuma Co., Ltd.). Takuma Corporation is now a research and development company that applies for 10~30 patents every year.
