October 25th is designated as “Karate Day” in Okinawa.

On this day in 1936, prominent Okinawan masters gathered in Naha and formally adopted the term Kara-Te 唐手 (empty hand). The masters present included Hanashiro Chomo (1869-1945), Kyan Chotoku (1870-1945), Motobu Choki (1871-1944), Miyagi Chojun (1888-1953), Kiyoda Juhatsu (1886-1967, Chibana Chosin (1885-1969), and Shinpan Shiroma (1890-1954).
*The three highlighted in bold text are Shimabuku Tatsuo’s teachers.

Large Karate demonstrations, like the following video, are held in Okinawa on October 25th to commemorate the Meeting Of The Masters and celebrate the Okinawan art of Karate.
