Since our founding in 1981, Joyakukenkyujyo Co., Ltd. have been doing business exclusively with reishi mushrooms for more than 35 years.we were founded as an affiliated company of Tanaka Shoji Co., Ltd., a gas trading company. The first generation was called Shozo Tanaka.At that time, I heard that the reishi mushroom, which was called "monkey's koshikake" at the time, was said to be good for health.If Reishi is that good, let more people know about it. In 1981, the fourth son, Toshio, established a reishi health food business as an affiliated company that was completely different from the gas business, and started the business. At that time, health foods were flooded with sloppy products.At the time of the founding of an affiliated company in the health food business, the second son, Minoru, who became the third president of Tanaka Shoji, and the fourth son, Toshio, made a vow.That is, "If we are going to do it, let's make the best Reishi mushroom products in Japan."After that, after the health food business was integrated into Tanaka Shoji, in 1998, the current president, Shinichiro Tanaka, who is the eldest son of the third president of Tanaka Shoji, spun off as an independent company to broaden and deepen the health food business of Reishi. deployment.
