Someya Chikatoshi was the founder of Meifu Shinkage ryu.
From a young age, Someya sensei had a passion for samurai culture, and traditional Japanese martial arts. Started in 1940 training in Tenshin Shoden Katori Shinto Ryu.
Someya sensei developed a special interest in shurikenjutsu, and other kakushi-buki, hidden/concealed weapons. He researched the weapons, and techniques, of many traditions. He had a great interest in the study of the shuriken and spent years studying and developing his own design of shuriken.
After many years of study he founded a new school based on his studies, calling his school Meifu Shinkage Ryu.
Otsuka-sensei is the current soke of Meifu Shinkage Ryu. As a child Otsuka-sensei studied karate, with his father & also kendo in school.
Sensei had an interest in throwing objects at an earlier age, developing an interest in throwing shuriken on his own. He did not have a teacher, so figured out a way that worked for him.
In 1980, while studying at university, Otsuka-sensei found the book “Shurikenjutsu Nyumon” by Someya-sensei. He was pleased to see that his own approach to throwing shuriken was similar to the method described in the book. Inspired, he continued to practice on his own until he could officially join Meifu Shinkage Ryu (1985).
Training was held every Sunday afternoon at Someya sensei’s house. Otsuka sensei threw himself into the training, and was licensed as shihan ( master instructor) in 1991.
He was one of four people to receive this license. However, by the time Someya sensei passed away in 1999, Otsuka-sensei was the only active teacher.
