Nagaoka Zen Training Center

The Nagaoka Zen Training Center (Nagaoka Zen Juku) was established in 1936 by Katsujiro Iwai, the founder of Iwai & Co. Ltd., one of Sojitz's predecessor companies, for the purpose of promoting a Zen-based background to education and providing scholarships. Numerous students and working people active in many fields have partaken of Zen teachings at the center. As a member of the Saishokai Group, which is the corporate group of Iwai & Co., Ltd., Sojitz will continue to support the center and carry on the spirit in which it was founded.
