A new hot spring inn, Gensen Itto Minami-Izu, opened in Shimogamo, Minami-Izu Town, Shizuoka Prefecture on June 1, 2026. The inn is the first property under the newly launched "Gensen Itto" brand, which focuses on the power of natural hot spring sources. Formerly operating as Hana no Omotenashi Nanraku, the property has been rebranded to offer guests an immersive experience combining the area's abundant natural hot springs with ultra-fresh seafood from an on-site live fish tank.

The Hot Spring Source at Gensen Itto Minami-Izu
The inn draws from two natural hot spring sources, "Kujō" and "Daifuku," located in Shimogamo Onsen in Minami-Izu — an area nourished by the warm Kuroshio Current. These springs reach a maximum temperature of 71.4°C and produce approximately 230 liters per minute, with one of the highest salinity concentrations in Japan. The spring type is sodium-calcium chloride water. The mineral-rich salt layer locks in heat to warm the body from the core, while abundant metasilicic acid leaves the skin feeling silky smooth — earning it the nickname "beauty hot spring."
Private Outdoor Baths and Large Open-Air Bath
Guests can enjoy the hot spring water flowing directly from the source in a variety of private outdoor baths (rotenburo), as well as a large bath with an adjacent open-air section. Multiple bath styles with different atmospheres are available for a relaxing bathing journey.
Note: Some private outdoor baths require an additional fee. Please contact the inn for reservation details.
Dinner: Savoring Freshness Straight from the Live Fish Tank
One of the highlights of a stay here is the fresh seafood lifted directly from the inn's on-site live fish tank (ikesuu). Carefully selected seasonal ingredients are served at their absolute freshest.
A generous platter of "Five-Kind Sashimi Assortment" can be enjoyed as-is, or cooked in new ways such as ishiyaki (stone-grilled) or shabu-shabu to draw out even more depth of flavor. Additionally, freshly made nigiri sushi featuring more than 10 types of fish at any time — including flounder, tuna, and sea bream — is prepared to order. Guests can enjoy as much as they like, savoring the incredible freshness straight from the live tank.
Note: The menu content may be partially changed depending on the day's catch.
Breakfast: The "San-no-Zen" Style Morning Meal
Breakfast showcases locally sourced ingredients in a visually stunning spread. The meal is served in the "San-no-Zen" style, which includes piping-hot simmered kinmedai (splendid alfonsino) from Izu Shimoda, Izu brand beef soboro donburi, a colorful hako-zen box set with nine side dishes, and handmade tofu — a truly flavorful start to the day that reflects the bounty of Minami-Izu.
