ONE FES -imizu music festival-May 3 (Sun) – 4 (Mon), Toyama Prefecture

This open-air music festival from Toyama was named by combining the “wan” of Toyama Bay with the desire to create “the place in the prefecture that gathers the most smiles and love.” Set in Imizu City’s Kaiwomaru Park—one of the prefecture’s premier locations with views of the Shinminato Bridge, the sailing ship Kaiwomaru, and the towering Tateyama Mountain Range—local volunteers continue to hold the event to contribute to the community through music and food. A hallmark of the festival is its family-friendly focus, with nursing rooms, diaper-changing stations, and play areas for children. It will be held over two days during Golden Week in 2026.

ONE FES 2025 will be held in Toyama in May!
