Why go, and how to do it well
Tucked into a quiet soi off Sukhumvit 49 in the Watthana district, this spa brings Japanese onsen culture to Bangkok, offering both private and public hot spring bathing alongside massage and spa treatments. Visitors consistently describe the atmosphere as calm and authentically Japanese, making it a genuine departure from the city's energy and a notable alternative to conventional Thai spa experiences. The facilities are well-maintained, and staff are attentive to individual preferences during treatments.
The venue caters to couples and solo travelers alike, with private onsen options available for those seeking a more intimate experience. The hot springs are clean and the interior carries a quietly peaceful aesthetic that guests find transporting — several reviewers describe it as feeling like stepping into Japan rather than Bangkok. Massage services accompany the bathing experience, and staff can be directed on pressure and focus areas during sessions.

**Absolutely Amazing Experience!** Kashikiri Onsen and Spa Sukhumvit 49 is an incredible place that truly feels like stepping into Japan. The vibe and atmosphere are so peaceful, quiet, and relaxing—perfect for unwinding and escaping the busy city. I booked the **Onsen (45 mins) + Scrub (45 mins) + Aroma Oil Massage (60 mins)** in a VIP room for 6,890 Baht (paid in cash), and everything was just perfect. The facilities were spotless and beautifully designed, making the entire experience feel luxurious. The highlight for me was the aroma oil massage—the oil was so thick and rich, providing the perfect texture for a deeply relaxing massage. The therapists were incredibly skilled and attentive, ensuring every moment was enjoyable. If you’re looking for a serene, authentic Japanese-style spa experience in Bangkok, I highly recommend Kashikiri Onsen and Spa. It’s worth every penny, and I can’t wait to visit again!
I love public onsens in Bangkok and I was looking for a private one to try out with my husband. Kashikiri is the first onsen we went together to here and we both loved it a lot! The place is clean and welcoming, very chill and has cute japanese decorations. You get a welcoming tea drink and a locker to store your clothes. After the onsen they take you to a massage room, we had a 60 min thai massage and it was very relaxing 😌
Have make an reservation one week before arrival, They will give you a form to fill up to circle area where you need to have more strength, SO even during the massage I have told her to put more strength but through out the 80-90 mins she just go around rubbing my body and legs... I'm so looking forward end up with a very disappointment for the massage. Onsen spa 45 mins & 90 mins massage 5290 baht. Please don't waste your time and money coming to this place.

Tips for Visiting Wellness & Spas
Communicate Pressure Preferences
Thai massage can be intense. Say 'bao bao' for lighter pressure or 'nak nak' for harder. A good therapist will check in, but don't hesitate to speak up — suffering in silence defeats the purpose.
Book Longer Sessions
A 60-minute massage is fine, but 90 or 120 minutes allows the therapist to work thoroughly. The price difference is often only 200–400 THB for an extra hour — worth it for a deeper, more relaxing experience.
Try a Herbal Compress
Add a herbal compress (luk pra kob) to your massage — steamed bundles of lemongrass, turmeric, and camphor pressed into sore muscles. It's deeply therapeutic and uniquely Thai. Usually just 200–300 THB extra.
