Ōnosato earned the nickname 'Sumo god' because of his warm personality and his enthusiastic guidance of young wrestlers, and he became popular with many rikishi.

One day after the January banzuke release, 32 Dewanoumi ichimon (clan) wrestlers gathered at a Chinese restaurant named Shunjuen, located in Tokyo's Oimachi district.

The Association was faced with an unprecedented crisis never before seen in the history of professional sumo and responded quickly to the group's demands, but their responses were considered to be half-hearted and lacking in substance, and eventually, the negotiations collapsed.

[7] The day after the news of Onosato's death, the Dewanoumi ichimon received a final letter from Ōnosato in which he expressed his concern and encouragement for his Kansai disciples who had returned to the stable.

[9] In April 2023, his shikona, or ring name, was given to Nishonoseki stable wrestler and amateur tournament star Daiki Nakamura.

Although the shikona doesn't feature exactly the same kana (大の里/大ノ里), it has been noted that before giving Nakamura his ring name, his master (former yokozuna Kisenosato) consulted a former stablemate, Wakanosato, so that the latter requested permission from Ōnosato Mansuke's family who still reside in Aomori Prefecture.
