classes were grueling, and as below, Okazaki taught different courses to different individuals. Around the time of the founding of Kodenkan it took approximately four years to earn a Shodan ranking. During this time students trained 6–7 days a week. Seifukujutsu "Upon completing about a year of study," Okazaki wrote in his Esoteric Principles (contained in the Mokuroku scroll given to his pupils who mastered his system), "I acquired a body of iron" (paraphrased), so he dedicated his life to the study of martial arts and the healing techniques associated with each style he took up. Some among his students carried on his healing traditions. In 1984 third and fourth generation devotees standardized his style of massage from notes by Okazaki's students into the AJJF certification program in Okazaki Restorative Massage (recognized by the AOBTA as ORM, but also known as Okazaki Long Life, Nikko Restorative Massage). World War II and later Shortly after the Japanese attack on Pearl Harbor, on December 7, 1941, Okazaki was allegedly interned for six months. This is alleged, but not substantiated through FOIA requests to the U.S. Government. It is possible that he was only held under arrest and not placed in an internment camp. He was released relatively quickly because of the intervention of Curley Freedman who used his FBI contacts to aid in Okazaki's release. Curley was the first tile contractor in Honolulu, and installed tile in the homes and businesses of many Japanese. Because of his craftsmanship, he was well liked and widely known. The FBI asked Okazaki for his assistance in identifying Japanese fishing boats that may have been contacting Japanese submarines and relaying information about U.S. Navy activity in Pearl Harbor. The FBI would also ask Bud Estes, who worked for Curley in the tile business, to assist in identifying drug dealers on another island during the harvest period. As Bud had knowledge of the island from his Salvation Army missionary days, he agreed and assisted the FBI until his cover was blown. Okazaki was also fortunate in that his dojo was unmolested, as his students protected it from looters who ransacked Japanese homes and businesses. Because of the preservation of his assets, he was able to lend aid to the Asian community, members of which had formerly shunned him. In this way he became accepted by them. During wartime, Okazaki continued teaching and also assisted the US military
