Imanari left catch wrestling-based team Team Roken in 2008 and founded Nippon Top Team with Shinya Aoki and Satoru Kitaoka. However, Aoki left for Evolve MMA of Singapore, whereas Kitaoka joined Lotus Paraestra, Setagaya branch of Paraestra. Consequently, Imanari founded his own team, Imanari Jiu JItsu. Imanari is an A-level shoot wrestler (better known as catch wrestling in the west) under Yuki Nakai. He was later also presented a Brazilian jiu-jitsu black belt by Marco Barbosa. ==Fighting style==

Imanari is primarily a grappler, and is universally known for his skill and preference for leglocks, which gained him the nickname of "Ashikan Judan" ("The Great Master of Leg Submissions"). Though his striking game is considered inferior, or by way of ashi garami. He stands out for his dexterity in toehold and heel hook variations, and is an avid user of the 50/50 guard in order to transition between submission attempts. The "Imanari Roll" (rolling from a stand up position into a leglock) and the "leggy neck choke" (a combination of an omoplata and a rear naked choke) are grappling moves named after him due to his usage of them. ==Championships and accomplishments==
