I wanted to clear things up, following some comments on the Jim Frederick involvement with the recently published Japanese Charles Jenkins autobiography. I checked with Jim, and KOKUHAKU is indeed the book he wrote with Jenkins. When the publisher asked if he wanted to be mentioned in the Japanese edition, he decided that it wasn’t necessary (he still shares the full copyright with Jenkins though). But if the book comes out in English (there’s still no publisher for an English-language edition) his involvement should be made more clear.
Also, last week’s issue of TIME ASIA featured an excerpt from the book, which you can read here.
