The 2025 World Athletics Championships (Japanese: 2025å¹´ä¸ÂçÂÂé¸ä¸Â競æÂÂé¸æÂÂ権大ä¼Â) were the twentieth edition of the World Athletics Championships, and were held from 13 to 21 September 2025 in Tokyo, Japan.
The championships used the National Stadium, rebuilt for the Tokyo 2020 Olympic and Paralympic Games. Full capacity attendances were permitted at a major sporting event in Japan for the first time since the COVID-19 pandemic in the early 2020s (the most recent with full capacity had been the 2019 Rugby World Cup).
This was the third time that the championships were held in Japan, following the 1991 event in Tokyo at the former National Stadium, and the 2007 event in Osaka.
K, member of the Japanese boy band &TEAM, was selected as the official supporter for 2025 World Athletics Championships.
A total of 53 nations won medals at the championships, more than in any previous edition. Samoa, Saint Lucia and Uruguay won their first ever medals at the championships, while Tanzania won their first ever gold medal. The United States has won the most medals in the latest edition of World Athletics Championships, with over 450 total medals.
In October 2019, World Athletics president Sebastian Coe stated consideration of a direct choice for Kenya to host this championship.
Kenya confirmed its bid for the championships in October 2021.
In 2022, Japan and Singapore entered bids to host the championships. In July 2022, Tokyo was selected by World Athletics to host the 2025 event, after it scored the highest in the bid evaluation. The National Stadium in Tokyo became the first major spectator event for athletics after the 2020 Summer Olympics were held behind closed doors in response with the then-still ongoing COVID-19 pandemic. Coe welcomed the selection, but stated that his "ambition to see a World Championships in Africa... is undiminished".
World Athletics approved the timetable and qualification system for the 2025 World Athletics Championships on 31 July 2024.
The qualifying window for the marathon and 35 km race walk was 5 November 2023 until 4 May 2025. For the 10,000 m, 20 km race walk, combined events and relays, the window ran from 25 February 2024 to 24 August 2025. For all other events, entry standards could be achieved from 1 August 2024 to 24 August 2025.
The qualification system for the championships was based on a combination of entry standards and world rankings. The entry standards were set with the aim of qualifying about 50% of the athletes.
The top five finishers at Platinum Label marathons and winners of individual events at area championships (except for the marathon), regardless of marks, were considered as having achieved the entry standard.
The top three athletes in the 2024âÂÂ25 World Athletics Cross Country Tour â not qualified through entry standards or other ways â were deemed to be qualified for the 10,000 m.
The 2025 World Athletics Relays in Guangzhou, China were used as a qualifying event for the relays, with the top 14 teams in each event securing their place at the World Championships.
In August 2024, World Athletics released the timetable for the championships. M = morning session, E = evening session
