In June 2025, the first-ever KAGA SPATrail Endurance 100 by UTMB® was held in Kaga City, Ishikawa Prefecture. As the only UTMB® World Series race in Japan, it welcomed runners from across the country and around the world, sharing with the world the irreplaceable beauty of Kaga—where expansive nature and deep-rooted hot-spring culture come together.

The 2026 edition marked a significant step forward. We welcomed a remarkable field of international runners from all seven regions of the world and from 55 countries, creating a truly global gathering in Kaga. Building on the lessons of the first year, we improved course design, event operations, and athlete services one by one. These efforts led to a substantial rise in participant satisfaction, and runners, local residents, and tourism partners came together in a shared spirit that broadened the possibilities of sports tourism in Kaga City.

In 2027, the KAGA SPA Trail Endurance 100 by UTMB® will continue its evolution as we host the third edition of the event, striving to deepen its international significance. We are preparing so that runners from around the world may find new challenges, new discoveries, and moments of profound emotion here in Kaga.

We look forward to welcoming trail runners from across the world once again in 2027—inviting them to experience the rugged beauty and quiet grace of Kaga’s natural environment, and the heartfelt warmth of the people who cherish this land.

Matsuo, Basho, who visited on the way to “Oku no Hosomichi,” also really liked it, and wrote the poem “Yamanaka and chrysanthemums smell like hand-folded hot water” (you can live a long time just by soaking in this bath).

Hot springs are smooth, and local people use them, so you can also experience unadorned humanity.

Soyu is called Kikunoyu, and the men's bath and women's bath are separate buildings and are built next to each other.
