Shōshin Nagamine (長嶺 将真 Nagamine Shōshin?, 15 July, 1907 – 2 November, 1997) was a Japanese author, soldier, police officer and karatemaster. Early Life and Karate-do
Nagamine was born in Tomari, in Naha City, Okinawa. He was a small and sickly child, and he contracted a gastroenteric disorder in 1926, his second year of high school. He began a self-imposed diet and took up karate under the watchful eye of his next-door neighbour, Chojin Kuba. Nagamine soon became a picture of good health, crediting his recovery to "hard work both at school and training of Karate. His health improved to such an extent that he became a leader of the school's karate club, and his friends dubbed him Chaippaii Matsu, a nickname meaning "tenaciouspine tree".
After graduation in March 1928, he began to study martial arts full time, moving to Shuri and training under Taro Shimabuku (島袋善良)and Ankichi Arakaki. Later that year, he was conscripted into the Japanese army in the 47th Infantry Division, and fought in China before receiving an honourable discharge in 1931. Leaving the army, Nagamine sought an area in which his martial arts abilities would be useful, eventually settling on the police force.
During his time as a police officer, Nagamine received further instruction in karate from Chotoku Kyan and Motobu Choki, and achieved the title of Renshi in 1940. By 1951, Nagamine was aPolice Superintendent, of Motobu, and was training his own officers in karate. Nagamine retired as a policeman in 1952, and in 1953 he returned to Naha City and set up his own dojo, which he named "Matsubayashi-Ryu Kododan Karate and Ancient Martial Arts Studies". From the dojo he taught Matsubayashi-ryu, a karate school he had invented in 1947, and named in honour of Sokon Matsumura and Kosaku Matsumora. He continued to teach the discipline until his death in 1997. He was succeeded by his son, Takayoshi Nagamine, who is now the current sōke of Matsubayashi-ryu.
