2023 World Aquatics Championships
20th World Aquatics Championships

The 2023 World Aquatics Championships, the 20th edition of the World Aquatics Championships, were held in Fukuoka, Japan, from 14 to 30 July 2023. Originally scheduled to be held in 2021 as the 19th championships, the championships were postponed until May 2022 in response to the rescheduling of the 2020 Summer Olympics in Tokyo to 2021 due to the COVID-19 pandemic. The event was pushed back a second time to 2023 due to ongoing travel restrictions and safety measures in place in Japan. In its place, Budapest hosted the 19th Championships from 18 June to 3 July 2022, while the originally scheduled 2023 championships in Doha, Qatar, were moved to 2024.
It was the second time Fukuoka hosted the event having previously held the 9th World Aquatics Championships in 2001, with South Africa's Roland Schoeman (swimming) and Brazil-Spain's Felipe Perrone (water polo) the only two athletes to compete in both the 2001 and 2023 championships.
The championships included 2,392 athletes competing from 192 member federations. While originally listed as 195 nations competing, due to the status of their member federation with World Aquatics, athletes from both the Philippines and Kenya were required to compete under the banner 'Suspended Member Federation', while two athletes of Syria competed under the banner 'World Aquatics Refugee Team'. World Aquatics ban on athletes from Russia and Belarus remained in effect for these championships.
These championships were the first edition of the championships to be held under the new World Aquatics branding following the renaming of FINA (French: Fédération Internationale de Natation) in December 2022.

This brief starts where responsible research should: with the source description of “2023 World Aquatics Championships” as 20th World Aquatics Championships. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as 20th World Aquatics Championships. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 3, 2026. The linked authority identifier is Q14127363. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2023, 2021, 2022 and 2020.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
