Nagaoka Zen Training Center

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 taken part in Zen teachings at the center. As a member of the Saishokai Group, the corporate group of Iwai & Co., Ltd., Sojitz will continue to support the center and carry on the spirit in which it was founded.

Saishokai Youth Committee Members Create Zen-Themed Picture Book

The Youth Committee, a subcommittee of the Saishokai, is made up of young and mid-career employees selected from Saishokai member companies who come together every year from May to the following February to conduct research activities on a set theme for close to an entire year. In FY2019, 12 participants from 9 member companies—including Sojitz—took part in the Saishokai Youth Committee, creating a picture book called Sai no Katsujiro (“Katsujiro the Rhino”). The theme of the book focused on Zen-related concepts in honor of the Zen spirit that Katsujiro Iwai emphasized in his business and management practices. The Youth Committee participants then visited a preschool to read the book aloud to children.

  • Members read books to classes of children aged 2 to 5
  • After the readings, the members donated books and kamishibai boards (picture boards used to tell stories) that they created
