About this event
'Ichi-Ni-no-Sanmu Sports Day' is a participatory sports day where four areas—Sanmu City, Sanmu District (Shibayama Town, Kujukuri Town, Yokoshibahikari Town), Togane City, and Oamishirasato City—form teams to compete in inter-regional competitions. It will be held on Monday (public holiday), October 12, 2026, at the grounds of the former Hasunuma Junior High School. Both participating in events and spectating are free, and a wide variety of competitions are scheduled, from serious competitions centered on adults to parent-child events and unique novelty games. On the day, a professional MC will host the event, building excitement across the venue with live commentary and announcements to create a lively sports day experience. A total of 12 food trucks and stalls are scheduled to open at the venue, offering great food. In addition, attractions such as yo-yo fishing and coin drops will be available. Event participants will receive a 500 yen Amazon Gift Card as a gift (some exceptions apply). On the preceding day, Sunday, October 11, the 'Ichi-Ni-no-Sanmu Sports Day Eve Festival' will also be held at the same venue, featuring stage performances and more.
