A Sulphur Spring That Changes Colour

• ♨️Milky white, pale green, jade — the source shifts colour several times a day
• 🔬Nobody has fully explained why; the science is still open
• 💧The colour only appears because the water is drained and refilled daily, never recirculated

An Open-Air Bath Facing the Sea

• 🌊Yogo-no-Yu, an open-air bath with a wide sweep of ocean
• 🗻On clear days Mount Fuji rises on the horizon
• 🎣After dark, the lamps of distant fishing boats glitter offshore

Four Parties a Night

• 🛁The maisonette Kichi-no-Ma room has its own open-air bath fed straight from the source
• 🌅The Minamiboso coastline spreads out from the balcony
• 🤫Only four parties a day, so the place is genuinely yours

Kaiseki From the Water Out Front

• 🦞Wild-caught ise-ebi lobster, abalone, kinmedai and more
• 🍱Kaiseki served in your room or in a private dining space
• 🌿The menu changes each time with whatever the day's catch brings
