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 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!

**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!

Great experience, we went in on a week day and had the whole place to ourselves. Service was solid, and the treatments were thorough and relaxing. Private onsen was nice and relaxing, the perfect amount of time before treatments. Plenty of parking although don't expect to leave at a normal time if you're getting picked up around 4-6, terrible traffic.

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.

Wonderful couples package with upgrade to the VIP Onsen is worth it. Downstairs is a spacious private Onsen and washing area for two while upstairs is the couples massage room. A wonderful relaxing morning

I recently visited Ka Shi Ki Ri Onsen and unfortunately felt unwell afterward. Having lived in Japan for four years, I greatly enjoyed the Onsen experience there. Returning to Thailand, I was eager to share this experience with my partner, but visiting during the summer proved to be a mistake. Despite this, the Onsen's location was excellent, and the facility was very nice and clean, evoking fond memories of Japan. The service was also exceptional. 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. However, I wasn't particularly impressed with the shampoo and soap products. Following our time in the Onsen, we enjoyed a very good massage. If you need some relaxation after a tiring day at work, Ka Shi Ki Ri Onsen is worth a visit.
