Amūru Mitsuhiro (阿夢露 光大, born August 25, 1983 as Nikolai Yuryevich Ivanov) is a former professional sumo wrestler from Lesozavodsk, Primorsky Krai, Russia.

He made his debut in May 2002 and, after a serious knee injury in 2012 sent him down the rankings, reached the top makuuchi division in November 2014.

With the help of the professional wrestler Akira Taue he was able to make a contact with former sekiwake Masurao, who was the owner of Onomatsu stable.

He opted against surgery, fearing he would be out for so long that he would fall off the banzuke completely, and instead worked on rehabilitating his knee injury.

[5] He could only manage five wins against ten losses in his makuuchi debut however, and was relegated back to the second division for the January 2015 tournament.

After two more winning records in July and September he reached his highest rank to date of maegashira 5 in the November tournament.

Amūru announced his retirement at a press conference at the beginning of the May 2018 tournament, citing a left shoulder injury that had reduced his power.

[6] As of 2020 he was working in a gym in Chiba Prefecture, and he teaches traditional sumo movements in both Russian and Japanese online.
