Above is a very early 1950's rare signed photo by Ryuho Okuyama given to my father. Born on February 21, 1902, Ryuho Okuyama studied long and hard in many traditional martial arts of Japan including Daito Ryu Aikijujutsu (under Hosaku Matsuda and Sokaku Takeda), Seigoryu Jujutsu, Hasegawakoryu Kenjutsu, Nito Ryu Kenjutsu, Sojutsu, Jojutsu, Kyujutsu, shurikenjutsu and others.
Okuyama was an instructor of Daito Ryu Aikjujtusu until 1939 when he combined his knowledge and experience of martial arts with healing arts and founded Hakkoryu Ju-jutsu on June 1, 1940. The organization was called Dai Nihon Shido-Kai. In February 1943 they moved to Kanda (Tokyo) and the organization was now called Hakkoryu Kobujuku. In 1945 they moved to the foot of the mountain Haguro. Hakkoryu was so named by Okuyama from the Japanese characters HA which translated means: Eighth and KO which means light. The oriental believes that the sun emits eight bands of light, (similar to the spectrum of red, orange, yellow, green, blue, indigo and violet). They believed that an eighth band of light also existed, which was very weak. In as much as Okuyama purposely taught the casting away of all strength when in combat, it was felt that Hakkoryu covered his style of in fighting quite appropriately as so developed the name and style of Hakkoryu Ju-jutsu. 

The Hakkoryu Symbol

The circular symbol of Hakkoryu and the HMAF was the crest of the Samurai General. The four diamonds are representative of the four eyes looking north, south, east and west. The Samurai was always prepared for attacks from all directions.
