He later moved to Antonio Inoki's Universal Fighting-Arts Organization, and then Kingdom Ehrgeiz, where he trained shoot fighting (a fighting style based on catch wrestling) and MMA with Hidetada Irie before doing his amateur debut.

ZST
Imanari gained popularity during his mixed martial arts career in Japanese promotion ZST fighting the likes of top Lightweights including Dokonjonosuke Mishima, Jorge Gurgel and Marcus Aurélio despite being a much smaller Featherweight. He defeated Gurgel, who is a Brazilian jiu-jitsu black belt former UFC fighter via catch wrestling staple submission (heel hook) while being lighter in weight. Imanari also defeated former Cage Warriors Featherweight Champion Danny Batten. In the first round Batten took Imanari down on the ropes but Imanari attempted a triangle choke.

Team allegiances
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, Imanari often engages in stand-up battles in order to bait the opponent to the ground, usually by dropping down after or while seizing control of his leg 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. He describes his signature leglock style as not based in sambo as it is popularly believed, but "purely self-taught", and explained his preference for it as "because it hurts the opponent".

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.
