The 2025 Summer Deaflympics, officially known as the 25th Summer Deaflympics or XXV Summer Deaflympics, was an international multi-sport event held in Tokyo, Japan from 15 to 26 November 2025. The multi-sport event commemorates the 100th anniversary of the Deaflympics, as the inaugural edition was kicked off in 1924. This was the first time Japan hosted the Summer Deaflympics. It marks the fourth time that an Asian-Pacific National Deaf Sports Association has been given the hosting rights of the Summer Deaflympics after New Zealand (1989), Australia (2005), and Taiwan (2009). The event returned to its usual four-year cycle, following the postponement of the 2021 Summer Deaflympics to 2022, due to the COVID-19 pandemic.
