Koyama Masashi sensei has been a well-known figure in Gōjū-ryū research in Japan for many years.
Internationally, he became particularly known through the book Karate – Its History and Practice, which he co-authored with Kadekaru Tōru and Wada Kōji.
Starting as early as 1980, Koyama published a 15-part series about Miyagi Chōjun (plus an additional article about his trip to Shanghai). In addition, many other contributions appeared, including an article about Higaonna Kanryō and an interview with the famous researcher of Chinese martial arts, Matsuda Ryūchi.
Incidentally, he demonstrated the kata Saifā in the famous series Nihon Budō Taikei.
But next to his excellent research, he was also a world champion in kata, and was de-throned by Sakumoto Tsuguo (Ryū‘ei-ryū).
My wife and I are fortunate that Koyama sensei has given us permission to translate his earlier series into English. At first, however, it will be a limited edition. If anyone is interested, please feel free to contact me. The text has been fully typed up and is waiting to be translated—may the translation begin !!!
After much consideration, I would like to publish the book in perfect quality, as a hardcover edition with a ribbon marker and other fine details.
