SOZU Onsen & bambina365: A Local Gem in Iwakuni, Yamaguchi

Introduction: A Hidden Gem in Yamaguchi
Looking for an authentic Japanese experience away from the crowds? We are thrilled to announce a special partnership with SOZU Onsen, a hidden “secret” hot spring nestled in the mountains of Iwakuni, Yamaguchi Prefecture.
The Charm of SOZU Onsen: 53 Years of Heritage
SOZU Onsen is a place where time slows down. With 53 years of history, it is famous for its natural radon-rich spring water, flowing directly from the source (Gensen-kakenagashi). It is a favorite among locals for its healing properties and the breathtaking natural scenery that surrounds it.
A Connection Born from Local Passion
The collaboration between SOZU Onsen and bambina365 started with a chance meeting at a local women entrepreneurs’ networking event. While our backgrounds are different, we shared a common heart: “To cherish and revitalize our local resources.” At bambina365, we upcycle local bamboo into skincare, while SOZU Onsen preserves the rich natural environment of Iwakuni.

Experience “Take Ururi” after Your Bath
Now, you can find our signature bamboo-based lotion, “Take Ururi,” at SOZU Onsen. The mineral-rich bamboo charcoal water is the perfect match for skin that has been warmed and softened by the hot spring. Special Offer: Visitors can receive a sample of “Take Ururi” at the reception. Please enjoy the gentle touch of Yamaguchi’s nature on your skin.
