It's one of the best books, next to Unearthed Arcana, that was published by E. Gary Gygax and the Company (TSR) he once owned. It has been in my collection for nearly 35 years. It greatly details the myths and mythologies of the far east and enables both DM and player to write up Asiatic classes (Kensai, Ninja, Samurai, Sohei, Wu-Jen, etc.) for the 1st edition Dungeons and Dragons game. Regardless of the political climate, this is one book any player needs to own and use.
