There are several books about the Kojo-ryu, and I would like to examine what is written about it. From the old books, we have Karate-do Kyohan, written by Tominakoshi (Funakoshi) Gichin, published on May 25, 1935 (Karate-do Kyohan Reprint, May 26, 1985, published by. Kazusa Co.) The text is in Volume 1, Chapter 3. History of Karate, page 9, last two lines.
The contents are as follows.

Part 4 – Okinawa Karate
Author Mark Bishop

In the above book, he wrote about an interview he conducted with the Kojo family in the 1970s, accompanied by an interpreter. It seems that he came from England to interview him at a time when almost no Japanese had come to talk to him about Karate. The photo of the 12 stances of the 12 signs of the Chinese zodiac were taken by Mr. Tatsumi Kojo. Now they are invaluable photos. The neko-ashi-dachi is very low. Foreign researchers have been enthusiastic since then. The book is still available on the Amazon site today.

A Visit to the Kojo Family

Fujiwara visits the Kojo family.

The first visit was in the summer of 1973 when he visited the Kojo home. He had received a letter of introduction from an alumnus , Mr. Noguchi, of the Waseda University Judo Club.
