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.

       Nagamine wrote two books in Japanese, The Essence of Okinawan Karate-Do        and Tales of Okinawa's Great Masters.

       The Essence of Okinawan Karate-Do, which has been reprinted many times,
       was first published in the English language in 1976. Tales of Okinawa's Great
       Masters received its first English translation in 2000.
