I just bought a new book by Kyoko Tachbana. Her book, Nobunaga and the Cross. I have read a little so far and it explains Nobunaga and the Tenka Fubu relationship. What is so great about the book is the reference material. It is a must to any Nobunaga fan. If there is one drawback, it is difficult to read, but a wealth of data. Tachibana Kyoko. Nobunaga to Juujika. Tokyo: Shueisha, 2004.
If anybody has read the book or knows any information about, let me know.
Nobunaga no Tame!
