is the premier annual badminton tournament in Japan. Organized by the Badminton Association of Japan (BAJ), it is held in December and serves as the primary selection event for the Japanese national team for the upcoming season. The tournament is open to Japan's top-ranked professionals, university students, and high school athletes who qualify through regional or category-specific preliminaries.

History The All Japan Badminton Championships was established shortly after the creation of the Nippon Badminton Association (NBA) in 1946. The inaugural All Japan Championship was held on 8–9 May 1948, at the Second Normal School Women's Department Gymnasium in Tokyo. The first champions were Junichi Oka (Kanagawa) in men's singles and Taki Nakamura (Kanagawa) in women's singles. Mixed doubles was included as a discipline from the very first tournament, with the pair of Hiroko Oka and Isamu Mori (Kanagawa) taking the title.

The tournament is traditionally held annually. However, the official edition numbering contains an anomaly dating back to 1962. To adjust the tournament schedule to align with the fiscal year, the association held two championships in a single calendar year: the 15th edition (for the 1961 fiscal year) and the 16th edition (for the 1962 fiscal year).

In May 2026, the BAJ changed the tournament's scoring format to a "3 games of 15 points" system. Following the Badminton World Federation's (BWF) decision to adopt this new system for international competitions beginning in January 2027, the BAJ implemented the rule a year early across its domestic Category 1 tournaments, which includes the All Japan Championships. The association stated that the accelerated timeline was intended to prepare players for the upcoming 2028 Los Angeles Olympics qualification race, as well as to mitigate nationwide issues regarding lengthy match times.

Under the official criteria set by the Badminton Association of Japan (BAJ), first-place winners in all five disciplines automatically qualify as National Team candidates for the upcoming year.
