Jirinn 21 Sanseido List Price: ¥5,000 July 1993, First Edition #Sanseido #Book #Language/Japanese I purchased it and barely used it, then left it on a bookshelf for 30 years. I am disposing of it due to organizing my books. The outer box shows signs of age, but the book itself is close to new. Yōrō Takeshi is listed as the supervisor. I believe the content is still sufficiently usable even in this era. Thank you.
