Founded in 1989, the event is the first robot-sumo event ever, introducing the Mega Sumo class. Since the introduction of overseas participants in 2008, it is considered the "World Robot-Sumo Championship" <ref name=":7" /> for Mega Sumo, both Auto and RC. Since 2023, it has also been officially hosting Mini-Sumo competitions (Auto and RC).<ref name=":1" />  

Currenlty, the competition is divided into a "Regional Stage" (Japanese: 地区大会 chiku taikai, [[Literal translation|lit]]: regional tournament) and the "Grand Final"  (Japanese: 全国大会 zenkoku taikai,  [[Literal translation|lit]]: all country tournament), also called "Final Round". The Regional Stage consists of regional tournaments held in Japan between August and October for participants based in Japan, with the top performers from each tournament qualifying for the Grand Final. The Regional Stage tournaments have usually been the [[Kantō region|Kantō]], [[Chūgoku region|Chūgoku]]-[[Shikoku]], [[:ja:北信越地方|Hokushin'etsu]]-[[Tōkai region|Tōkai]], [[Tōhoku region|Tōhoku]], [[Hokkaido|Hokkaidō]], [[Kansai region|Kinki]] and [[Kyushu|Kyūshū]] tournaments, though not all of them may be held every edition. The Regional Stage tournaments currently adopt a single-elimination format and are held in a single day.<ref name=":18">{{Cite web |title=ロボット相撲大会｜全日本ロボット相撲大会 - ALL JAPAN ROBOT-SUMO TOURNAMENT |url=https://www.fsi.co.jp/sumo/tournament/index.html#page1 |access-date=2025-01-19 |website=www.fsi.co.jp}}</ref> The FUJISOFT's "High Schooler's Tournament" and the "High School Championship" Regional Stage tournaments are also part of regional qualifiers for the All Japan Grand Final.<ref name=":23">{{Cite web |date=2024-12-02 |title=12月7日（土）、8日（日）、全日本ロボット相撲大会2024 決勝大会 “世界一のロボット横綱”を目指して、ロボット力士が両国国技館に集結！ |url=https://prtimes.jp/main/html/rd/p/000000127.000061382.html |access-date=2025-01-22 |website=プレスリリース・ニュースリリース配信シェアNo.1｜PR TIMES |language=ja-JP}}</ref>  

International representatives may qualify for the Grand Final through international qualifiers tournaments approved by FUJISOFT, in overseas countries such as [[Mexico]], [[Mongolia]] and [[Brazil]], among others. These tournaments form the "Overseas Tournaments" qualifiers (Japanese: 海外大会枠 kaigai taikai-waku, [[Literal translation|lit]]: overseas tournaments slots).<ref name=":21">{{Cite web |title=ロボット相撲大会｜全日本ロボット相撲大会 - ALL JAPAN ROBOT-SUMO TOURNAMENT |url=https://www.fsi.co.jp/sumo/tournament/index.html |access-date=2024-12-31 |website=www.fsi.co.jp}}</ref> The Overseas Tournaments are run by different organizations, so the tournament format varies. In some specific cases, qualification certificates are also issued to some teams as "National Representative" or "Country Representative", for countries with no teams yet qualified or without any official qualifier tournament.<ref name=":31" />

Between 2013 and 2017, FUJISOFT split the All Japan Grand Final in the "International Robot-Sumo Tournament", a tournament which functioned as the current Grand Final and a proper world championship in name {{NoteTag|Originally the "International Robot-Sumo Tournament 2013" was considered a test event, and was originally called the "International Robot-Sumo Pre-Tournament 2013". Currently, It is listed as part of the International Robot-Sumo Tournament without the status of a "test event".|name=Status of the International Robot-Sumo Tournament 2013}}, and the All Japan Tournament properly, which was reserved for japanese competitors and functioned as the japanese qualifier for the International (similar as other overseas tournaments).<ref name=":16" /><ref name=":25" /> In 2018, FUJISOFT reunified the competition under the name All Japan Grand Final, which once again functioned as the de facto world championship tournament (even with the "All Japan" in name).<ref name=":30" />  

As of 2024, FUJISOFT initially reserved for the All Japan Grand Final, for each of Mega Sumo categories, Auto and RC, a total of 57 slots for the Regional Stage (including the "High Schooler's Tournament" and the "High School Championship" Regional Stage tournaments) and 40 slots for Overseas Tournaments.<ref name=":21" /> While all japanese slots were filled, only 26 and 23 slots were filled by overseas representatives for Auto and RC, respectively. That edition had robots from 17 overseas countries qualified.<ref name=":23" />
