The event will be held on May 4, 2026.

The Oborozukiyo Music Festival is an open-air music festival hosted by the Iiyama Nanohana Festival Executive Committee, held at Nanohana Park in Iiyama City, Nagano Prefecture, where the scenery from the song “Oborozukiyo” remains just as it is. In its 25th edition this year, participating groups, including city music organizations, will perform the song “Oborozukiyo” and a free-choice piece on an outdoor stage surrounded by blooming canola flowers and fresh spring greenery. Aiming to nurture mental well-being by immersing oneself in the hometown landscape and enjoying the richness of nature, the festival will be held in May 2026.
