IFS — International Sumo Federation

What is the IFS?

The International Sumo Federation is the world governing body for amateur sumo. It was formally established on 10 December 1992 and is administered from Tokyo.^[1] [2] A secondary reference describes it as the largest international governing body for the sport and states that it is the only sumo organisation recognised by the International Olympic Committee and the World Anti-Doping Agency.^[3]

It is not the body that runs the sumo most readers have seen. Professional sumo in Japan is the business of the Japan Sumo Association, a public interest incorporated foundation under the jurisdiction of Japan's education and sports ministry, which stages the six annual honbasho.^[8] The IFS governs the amateur, weight-classed, international version of the sport, with men's, women's and junior competition, and it is the IFS rather than the JSA that holds the standing in the Olympic structures.^[1] [3] The two are separate institutions and the distinction runs through everything else on this page.

What does the IFS govern or do?

The federation administers international amateur sumo: sanctioned competition, the weight-class system, continental structures and anti-doping. Amateur tournaments are contested in openweight, heavyweight, middleweight and lightweight categories, with separate divisions for men, women and juniors aged 13 to 18 — a competition format with no counterpart in the professional Japanese sport, which has no weight classes and no women's division.^[3] [7]

Below the world level the federation works through six continental federations, all established in 1995, each of which holds its own championships.^[1] National federations affiliated to the IFS are the entry route for competitors, so selection for the Sumo World Championships runs through them rather than through any professional stable system — the arrangement covered under national team selection.^[1]

The federation states an explicit institutional objective as well: securing recognition for the sport in the Olympic structures, which is what the amateur competition programme is organised to support.^[3] [2] Its relationship to the professional game is covered on this site under professional and amateur.

When was the IFS founded and where is it based?

The federation's own organisation page separates the steps. Japan and Brazil created what it calls the forerunner of the present-day International Sumo Federation in July 1983; the IFS itself was formally established on 10 December 1992; and the six continental federations followed in 1995.^[1] An independent reference gives the same establishment date of 10 December 1992 and notes that it followed the growth of amateur sumo competition from 1980.^[4]

None of those dates should be confused with 1 September 1946, the founding of the Japan Sumo Federation — the Japanese national body for amateur sumo, and the IFS's member in Japan — or with the Japan Sumo Association, incorporated as the All Japan Sumo Association on 28 December 1925, which governs the professional sport.^{[1] [4] [8]}

On the headquarters, sources conflict. The IFS gives a Tokyo address at 1-15-20 Hyakunincho, Shinjuku-ku, and an independent reference also places it in Tokyo; the ARISF member listing gives Lausanne.^{[1] [4] [5]} This page follows the federation's own address and flags the discrepancy.

How is the IFS recognised?

The recognition claim is dated and specific, and comes in the first instance from the federation itself. Its organisation page states that the IFS has been an IOC recognised federation since 2018 and was provisionally recognised from 2001; that it has been a member of ARISF, the Association of IOC Recognised International Sports Federations, since 31 January 1998; that it joined SportAccord on 16 October 1999; and that it joined the International World Games Association on 22 November 2002.^[1]

Three of those are independently checkable. ARISF's member list includes the International Sumo Federation, though the listing does not give a joining date.^[5] The IWGA states that the IFS has been an IWGA member federation since 2002, matching the federation's own date.^[7] An independent reference records the federation as IOC-recognised and an ARISF member, and separately gives 1998 for the ARISF affiliation.^[4] [3]

Recognition is not the same as inclusion. Sumo is not on the Olympic programme, and no sumo event has been contested at the Olympic Games; IOC recognition places the federation within the Olympic Movement and makes the sport eligible to be proposed, nothing more.^[3] [5]

What does the IFS organise?

The federation's principal event is the Sumo World Championships, held each year since 1992 apart from the interruptions noted below, with a women's championship added in 2001 and contested alongside the men's event.^[6] [1] It also runs junior world championships, first held in 1999, and junior women's championships, first held in 2008, and the six continental federations run their own regional titles.^[1] The championships have been disrupted more than once: a 2009 edition was cancelled during the influenza pandemic and the 24th edition, originally scheduled for Russia in 2022, was rescheduled to Tokyo in late 2023.^[6]

The other programme is the World Games. The IWGA records sumo on the World Games schedule from 2001 to 2022 — Akita in 2001 as an invitational sport, then Duisburg 2005, Kaohsiung 2009, Cali 2013, Wroclaw 2017 and Birmingham 2022 — with the sport scheduled to return at Karlsruhe in 2029.^[7] That is the highest multi-sport stage at which international sumo is currently contested, and the site's world champion entry records the world championship titles rather than the professional Japanese yusho.

Who are its members?

Membership is by national federation. The IFS states that it currently has 88 member countries and territories, grouped under six continental federations.^[1] The figures reported differ: the federation's own front page says 84 nations have joined, its organisation page says 88, and the ARISF listing gives 87 member national federations and five continental bodies.^{[2] [1] [5]} This page reports the range rather than choosing between them. A secondary reference gives over 87 member countries, which is consistent with the same range.^[3]

The important structural point about the membership is who occupies the Japanese seat. The IFS's member in Japan is the Japan Sumo Federation, the national amateur body established on 1 September 1946, not the Japan Sumo Association, whose business is the professional sport and which has no governing role in the international amateur structure described here.^{[1] [4] [8]} Readers arriving from Japan or from the grand sumo tournaments are usually looking for that second body.
