Kashikiri Onsen and Spa Sukhumvit 49

I’ve been here 3x and I have to say that it is definitely the closest and most authentic you’d get to a real onsen in Japan, and by far the best onsen in BKK It’s also the most centrally located and accessible by public transport or if you drive. Inside the Onsen room, there was a large tub, and we could choose the fragrance for our bath. The room included a bucket of cold water with ice and a small area for towels and clothes i really enjoyed the experience and would definitely visit again when i have free time.

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.

I couldn’t have ask for a better experience. This was my first time trying an onsen and after experiencing it here, i definitely will be coming back again. Everything was perfect, beautifully decorated, and gave off such a cozy feel. It’s not cheap, but it’s well worth the price for what you get. Plus the yukatas were so cute! 😍👘

I truly enjoyed my time here. The onsen has a calm Japanese atmosphere that makes you feel peaceful right away. The hot spring was clean and relaxing, and the staff were very kind. I’ll definitely come back again!

I tried this onsen for the first time and honestly loved it! The vibe is so peaceful, and the staff made me feel really welcome. The onsen itself is beautiful and clean, and they even offer tea afterward such a nice touch! If I had to point out something, the parking space is quite limited, and it can get busy on weekends. But overall, it was such a relaxing experience. I’d totally recommend coming here for a weekend treat.

**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!

This has been one of the most wonderful and unique experiences I’ve had. The 2 best hours of my life. I have been spoiled by life! I will never enjoy the same just a regular massage, I always want to have the full experience with the bath. But thank you, I highly recommend it to any one who wants to relax and enjoy of a unique experience.

The onsen here has such a calm and relaxing atmosphere. The place is clean, cozy, and very private. The Japanese-style ambiance makes you feel like you’re actually in Japan! 💭 The staff are friendly and the service is great. Perfect spot to unwind and recharge on your day off.
