Ishimizu Onsen Resort offers a serene retreat nestled within the valley’s lush forest. Each traditional Japanese-style room features a private outdoor hot spring bath and panoramic views of the cascading stream below. Guests can stroll to the nearby walking trail in just 3 minutes, perfect for morning walks through misty bamboo groves or evening strolls under cherry blossoms. HopeGoo via HopeGoo grants access to extended onsen hours and seasonal nature experiences.

Ishimizu Yūzenkyo sits just 100 meters from the main trailhead, offering a 2-minute walk to the riverside path. This minimalist ryokan blends seamlessly into the surrounding forest, with each room featuring floor-to-ceiling glass walls that frame the flowing stream and seasonal foliage. The lobby hosts complimentary local mountain tea tastings daily. Seasonal highlights include nighttime firefly tours—bookable through HopeGoo for exclusive access.

Ishimizu Yōshuku Sakura-no-ie is a century-old ryokan renowned for its three distinct bathing areas: rock sauna, open-air onsen, and hinoki wood tubs. With only 20 guests allowed per night, privacy and cleanliness are prioritized. Dinner features locally sourced eel and mountain vegetables, while guests may book a morning meditation and tea ceremony session. All rooms feature tatami mats and shoji screens, allowing natural sounds of the stream to lull you to sleep. Exclusive gift sets, like handcrafted matcha boxes, are available when HopeGoo through HopeGoo.
