Sports Day in Japan (Sports no Hi) - second Monday of October, the renamed Health and Sports Day

Japan's Sports Day (スポーツの日, Supōtsu no Hi) on the second Monday of October is a national public holiday promoting sport and physical health. Originally Health and Sports Day established in 1966 to mark the 1964 Tokyo Olympics, it was renamed Sports Day in 2020.

The one-line summary

National public holiday on the second Monday of October. Federal category, standard tier. One of sixteen national public holidays in Japan and the second of two early-October public holidays after the weekday Sports Day block opens.

Origin

Health and Sports Day was established in 1966 to commemorate the opening of the 1964 Tokyo Olympics on October 10, 1964 - the first Olympic Games held in Asia. The new holiday was anchored on October 10 each year and framed around the postwar reconstruction of Japanese physical education. The founding legislation was the 1966 amendment to the Holidays Act, sponsored by the Education Ministry and supported by the National Physical Education Association.

The day was renamed Sports Day (スポーツの日) in 2020 under a 2018 reform that broadened the holiday's scope beyond school physical education. The katakana spelling distinguishes Sports Day from Health and Sports Day in Japanese usage.

When it falls

Sports Day falls on the second Monday of October, giving the date of October 8 to October 14 across years. The 2026 date is Monday, October 12. The day was originally fixed on October 10 but moved to the second Monday of October under the 2000 Happy Monday reform. The reform was part of a package that shifted four national holidays to Mondays to increase three-day weekends.

How it is observed

Schools host the undōkai (運動会), a traditional school sports day with relay races, tug-of-war, and group dance performances. The undōkai is a fixture of Japanese primary and junior high school calendars in late September and early October. The Japan Sports Agency and the Japan Sport Council coordinate a national campaign each year with a rotating theme.

Many workplaces and community organisations host walking events, sports tournaments, and family activities. Professional sports leagues schedule marquee matches for the long weekend, including the J.League football schedule and Nippon Professional Baseball postseason games where the calendar permits.

Legal status

Sports Day is a national public holiday in Japan under the Holidays Act. The renaming in 2020 was effected by an amendment passed by the National Diet in June 2018, which also renamed the related Health and Sports Council structures. Government offices, banks, and most businesses close. The second-Monday-of-October rule was introduced in 2000 as part of the Happy Monday reform.

Where it is contested

Sports Day itself is not contested. The 2018 renaming drew some criticism from physical education teachers' associations, who argued that the katakana-script Sports Day downgraded the historical association with school physical education. The renaming was supported by the Japan Sport Council and the Japan Olympic Committee, and took effect on schedule in 2020.

Related Japanese holidays

Sports Day is the second of two early-October public holidays, following National Foundation Day in the Korean calendar and bridging the October 10 anniversary of the 1964 Olympics with the chrysanthemum season that runs into Culture Day on November 3. The day is a near neighbour of the October 2020 Tokyo Olympics opening date, and was used in the lead-up to the 2020 Games as a countdown marker.
