White mineral sand and natural sea salt
gently dissolve the fatigue
sleeping deep within your body.
Step into your own private sanctuary,
away from the noise of everyday life.
Nine floors above the streets of Sasazuka, Shibuya — beyond the city noise — a quiet door awaits you.
Pasir Putih means "white sand" in Indonesian. Our sand salt bath blends Australian natural sand, Mexican rock salt, and pure essential oils to create a deeply warming, far-infrared heat experience that detoxifies from the inside out.
Completely reservation-based and women-only — so you can truly let go, at your own pace, in total privacy.

A blend of Australian natural sand and Mexican rock salt generates far-infrared heat — a type of thermal spa that warms your body from its very core is extremely rare. Promotes circulation to ease stiff shoulders, cold sensitivity, and swelling, while the mineral-rich salt also benefits your skin.

Every guest's time is carefully reserved so you can be yourself and relax at your own pace. You wear a gown throughout your visit, so there's no need to worry about being undressed. All staff are women, of course.

Warming the body from within is widely believed to support immune function and overall circulation. As your metabolism rises, your body feels lighter and it becomes easier to maintain good condition, while your immunity also improves. Many guests visit regularly with their health and wellbeing in mind. Take the first step toward raising your core temperature.

An optional aroma massage is available (separate fee / advance reservation required). Our experienced therapists gently release tense muscles and skin, and refine your body lines. Don't miss the golden window right after the sand bath.

After your bath, enjoy our curated herbal tea blend alongside natural sea salt, Kishu Nanko plum, and Okinawan black sesame sweets. These help effectively replenish salt and minerals while promoting secondary perspiration.

Throughout the salon, you'll find ornaments personally sourced by the owner from Bali. With calming Asian resort-inspired interiors and lighting, essential oil aromas and healing music, let go of everyday stress and experience true relaxation.

All mobile phones and electronic devices are prohibited throughout the facility. In our modern world overflowing with information, take a moment to step away and indulge in the luxury of doing absolutely nothing.

Why not quietly focus on your pulse and immerse yourself in meditation with deep breaths? If you maintain your fast and rest at home afterward, it becomes an excellent intermittent fasting session. Tip: Notice how your sweat gradually changes from sticky and salty to smooth and clear.

Yoga on warm, unstable sand — can you imagine it? We hold monthly sessions on different themes. Our certified and experienced instructor leads with care, so beginners can join with confidence.
Book by phone or online. Take the elevator to the 9th floor — a whole new world awaits beyond the door. Please arrive at least 20 minutes before your appointment.
For first-time guests, we begin with a thorough consultation. Enjoy your welcome tea, choose your course, and complete payment — then our staff will guide you.
Change into your dedicated gown. Valuables can be safely stored in your personal locker. Please keep the locker key on you at all times.
Into the warm, prepared salt sand you go! Your whole body gradually heats from within. Staff will check on you every 5 minutes. Enjoy up to 15 minutes of sand bathing.
Rinse off the sand and salt in the shower. To preserve the mineral benefits, shampoo and body soap are not provided. Bringing your own is also not permitted.
Take the spiral staircase down to the lower floor. Rest on a reclining chair wrapped in towels and a blanket to promote further perspiration. Feel free to drink all the bottled herbal tea.
With your muscles relaxed and tension released, the effect of aromatic oils is maximized. Feel the power of aroma through your body, nose, and skin — an unforgettable moment.
Return to your locker and cool down as you prepare to leave. That's 2 hours — gone in a flash! Please stay well hydrated for the rest of the day, and if possible, we recommend resting quietly at home.
My first time trying a sand salt bath! The atmosphere was wonderfully calming and I felt so relaxed. I was amazed at how much I sweated. I definitely want to come back.
I sweated more than I expected and started to feel lightheaded, but the staff responded immediately with such care and warmth. Everyone was so kind and attentive from start to finish. I'll be back.
The only sand salt bath in Tokyo — I'd always wanted to try it. Opening the spa door, I couldn't help but say "Wow, it really is a sandy beach!" Soothed by the aromas and healing music, I was astonished by the incredible perspiration. My skin felt noticeably smoother — I'm definitely coming back.
Cold sensitivity had been a long-standing concern of mine, but after visiting for 3 months, my hands and feet feel so much warmer. The staff are incredibly kind, and I love that they always offer advice tailored to how I'm feeling that day. The herbal tea and Nanko plum are both delicious.
This is apparently the only place in Japan where you can experience a salt sand bath. It warms your whole body, improves cold hands and feet, and I sleep so much better afterward.
Finding this extraordinary space in central Tokyo — accessible after work or shopping — is such a treat. The atmosphere is wonderful, and I left thoroughly sweated and deeply relaxed. The herbal tea and Nanko plum afterward are the best.
Within just 5 minutes of being buried in the sand, sweat was pouring out — I was genuinely surprised! Completely women-only, so I can relax without worry, and the staff are just so attentive. Now it's the highlight of my week.
