Palo Alto Goshukan is a traditional Gojuryu school operated by Des Tuck Sensei, a California attorney who is a Japan-graded 7th degree black belt (6th degree JKF Gojukai) and who has trained in the Gojuryu style since 1970. He has been awarded the honor of Kyoshi.
Goshukan follows the 'brand' originated by the late Shuji Tasaki Sensei, who was, for many years, chief instructor in the Tokyo dojo of the late Gogen Yamaguchi (The Cat) until he formed his own group, Seiwakai in 1972.
Tuck Sensei is the longest-training active student of the late Leo Lipinski Sensei (1946-2018) and travels annually to Japan for advanced training. Lipinski Sensei was the only non-Japanese ever awarded 8th Dan by the JKF Gojukai.
In early 2019, Tuck Sensei resigned from Seiwakai and joined Gojuryu Karatedo Kenwakai, whose chief instructor is Akio Takahashi, 10th Dan. Takahashi Hanshi was the top fighter in Seiwakai until he left to form Kenwakai approximately 30 years ago. He is revered internationally as one of the best fighters ever produced by the Gogen Yamaguchi line of karateka.
This recent development has given new impetus to Tuck Sensei and his growing group of students, located in the US, Mexico and UK, and in other countries soon to be announced.
