He has been awarded one special prize for Fighting Spirit, one for Outstanding Performance and four for Technique, as well as seven gold stars for defeating yokozuna.

He is the owner of the Kitajin toshiyori kabu or elder stock, purchased from the former Kirinji in May 2018, indicating he intends to stay in sumo as a coach upon his retirement.

Upon entering professional sumo, he was allowed to debut as a makushita tsukedashi instead of starting at the bottom of the ranks, to reflect his amateur success.

His previous amateur success, his technique and his seemingly effortless championship fueled speculation that Endō could be the next big Japanese hope in professional sumo in a sport largely dominated by foreigners in the higher ranks.

[5] His success continued into his makuuchi debut in September 2013, where he scored a majority of wins, although he damaged his left ankle and dropped out of the tournament on Day 14.

After making a respectable comeback in November with a score of 6–9 from the rank of maegashira 7, he had his best result in the top division to date in January 2014, winning eleven bouts and the Fighting Spirit Prize.

Endō suffered a serious injury to his left knee after a bout against Shōhōzan on the fifth day of the March 2015 tournament, rupturing anterior cruciate ligaments and damaging the lateral meniscus.

A disappointing 4–11 in November however, was followed by a sprain to his right ankle in the January 2016 tournament (attributed to over-compensating for his previous left knee injury)[8] and Endō was demoted to the second division (jūryō) for March.

He returned to the top division in May 2016 and scored 11–4, although a defeat on the final day meant he missed out on a share of the Fighting Spirit prize.

In November he defeated three ozeki and yokozuna Hakuho but lost four of his last five matches to finish with a make-koshi 7–8 record, which cost him the Outstanding Performance Award.

Back at komusubi in September 2020, he withdrew on Day 11 with only three wins, after a build-up of fluid in his right knee related to his previous injury.

The risk of losing his makuuchi status was further increased when, on Day 10 of the March 2024 tournament, he suffered an eighth defeat at the hands of Kinbōzan.

[28] However, he lost his lead in the title race after suffering defeats from jūryō debutant and co-leader Onokatsu and former Sekiwake Wakatakakage, who won the tournament.

[29] Considered a local hero in his hometown of Anamizu, Endō gave his name to the municipality's stadium and his sanshō trophies are displayed there.

[30] Since his family still lived in Ishikawa Prefecture, Endō was part of a delegation of wrestlers from the prefecture (along with Ōnosato, Kagayaki and the former Tochinonada) sent on 6 February after the 2024 Noto earthquake; charged with symbolically presenting Governor Hiroshi Hase with the sums raised during the January tournament and donations from the Sumo Association.
