Master Joe Alvarado
Student of Grand Master Koyasu was one who brought Soryu Karate to Texas.
In 1930 Kanken Toyama left Taiwan, and moved to mainland Japan and on March 20th, 1930 established his home and dojo in the Shimo Meguro district of Tokyo.Toyama’s home was in an “L” shape. The short part of the “L” was his family’s two story residence. The long part of the “L” was the single story dojo with a high ceiling. Sensei Toyama named the dojo portion of his home the Shudokan. “Shu” means “to study”. “Do” means “the Way”, in this case, Karatedo. “Kan” simply means hall or building. In 1933 Toyama formed an organization called “Zen Nippon Karatedo Renmei” AJKF (All Japan Karatedo Federation). Therefore, his dojo was also known throughout Japan as “Zen Nippon Karatedo Renmei Sohombu” (All Japan Karatedo Federation General Headquarters) and his style know as “Okinawa Seito Karatedo”, which means “Classical Okinawan Karatedo”. . In 1895 the Dai Nippon Butokukai (Greater Japan Martial Virtue Society) was established by the Japanese government (Japanese Ministry of Education) to regulate all forms of Japanese Budo. The Butokukai recognized Sensei Toyama’s unique training and mastership of all forms of Okinawan Karatedo, and in 1937 gave him an exclusive license to promote to any rank (Dan) or teacher’s title (Shogo), regardless of the type of Karatedo the promoted individual practiced. He was the only Karatedo teacher in Japan or Okinawa to ever be given this kind of license. Some of the foremost Okinawan and Japanese Karatedo masters, who formed their own styles, received their 8th 9th or 10th Dan degrees or their teacher’s titles of Shihan or Hanshi from Kanken Toyama. Toyama passed away on November 24th 1966 at the age of 79. He actively taught until the last year of his life. His home continued to be occupied by his family, who allowed the dojo to be used by his students, but as per Toyama Sensei’s wishes, the name Shudokan was discontinued, and the dojo name was thereafter changed to the Kanken Toyama Memorial. Between 1930 and 1966, Sensei Toyama raised nearly 100 students to the Shihan level, and a few to the Hanshi level 10th Dan.
