2026 Asian Games

The 2026 Asian Games (2026年アジア競技大会), also known as 20th Asian Games (第20回アジア競技大会) and Aichi-Nagoya 2026, will be a multi-sport event celebrated around the Aichi Prefecture in Japan from 19 September to 4 October 2026. The prefecture capital Nagoya will be the epicenter of the events. Nagoya will be the third Japanese city to host the Asian Games, after Tokyo in 1958 and Hiroshima in 1994. The event is set to return to its traditional 4-year cycle, after the 2022 Asian Games in Hangzhou, China were postponed to 2023 due to the COVID-19 pandemic.

Bidding process
The Olympic Council of Asia (OCA) selected Nagoya to host the Games at their annual general assembly session in Danang, Vietnam, on September 25, 2016. The bid was initially in threat of falling apart after a budget dispute between Aichi Prefecture and its capital Nagoya, but was resolved, allowing the bid to be accepted. The OCA originally planned to choose the 2026 host city in 2018, but brought the planning date forward due to the intensity of the region's sporting calendar, including the next three Olympic Games between 2018 and 2022 (held in Pyeongchang, Tokyo and Beijing).

Costs
The city of Nagoya received an estimate of roughly ¥85 billion in costs from the Aichi Prefecture government for the event, 30% of which is expected to be covered by sponsorships and other revenue, while the remainder is planned to be split on a 70–30 basis between Nagoya and Aichi Prefecture.
