Seikendo

Return to wrestling and aftermath (1995–2016, 2026)

In 1999, attempting to return to the world of martial arts and to create something similar to Shooto, he created a martial art named Seikendo. It was a hybrid martial art similar to Shooto and MMA, but more akin to a traditional martial art—with focus on etiquette and ceremonials based on traditional Japanese imagery and ideals and spiritual and mental development—and focused on "street" self-defense rather then sporting events: Seikendokas would wear keikogis to simulate clothing, had rules that based on the principle it had a concrete floor, with groundfighting that focused on ground-and-pound, with no submissions allowed, and fighting was in an octagonal ring without ropes. Sayama also created a professional promotion by the same name to promote his martial art (as he had done to Shooto), which ran for three years and had five events before closing down in 2003.
