Hidden haven of truly authentic Japanese arts of therapeutic retreat
An adventure to Bangkok is exhilarating, as it is exhausting. After days out on your feet, trawling the day markets and exploring the endless streets in the blistering heat, you’ll be needing a serious session of pure R&R.
The hipster cafe district of Ekkamai hides one lesser-known gem that’s perfect for a recharge. Kashikiri Onsen and Spa, Thailand’s first private onsen-spa, offers guests the traditional Japanese hot spring experience in the privacy of their personal bathhouses. Depending on the package you choose, the onsen soak is then followed by a range of relaxing treatments, from massages to full body scrubs.
The best part? A one and a quarter hour-long private onsen-massage Kashikiri Balancing Bath package costs just1,150 baht - that’s under S$50!
Here is what you can expect from an afternoon at Kashikiri Onsen:
Pre Spa
Before stepping into Kashikiri, you have to swap your shoes out for a pair of wooden sandals. After greeting you at the entrance, the staff will direct you to the cosy air-conditioned waiting area, where you’ll be served some warm herbal tea.
The spa grounds are very well-maintained and clean, with thoughtful details and interior decor that imbue the place with a truly authentic Japanese feel. I used to live in Tokyo during my student time, in a Japanese-styled dormitory where we had public bath as daily ritual. The cozy ambience and Japanese traditional dolls ( matsu in Japanese ) reminded me of my memorable student time back then...


And the lucky cats...

The first thing to do is to select the bathwater for your onsen soak. Kashikiri offers two different types of water that they import from different prefectures in Japan, each with their own special benefits. Supposedly, there’s one with antiseptic properties, one for rejuvenating joints and one that aids in preserving the skin’s youthfulness. Myself, I chose the Ryujin bathwater for beautiful skin, and the water color is literally pink. Of course, pink - what else! Ryujin onsen comes from the Ryujin Onsen ( 龍神温泉 ), one of Japan's best onsen region, near the Hidakagawa riverLocationRyūjin, WakayamaRyujin Onsen is a Japanese onsen, hot spring located in Ryūjin village, now the part of Nakahechi town in Wakayama Prefecture. Ryujin Onsen was discovered in the 7th century by Ennogyoja, the founder of Shugendō. Kobo Daishi, founder of the Shingon Buddhism visited the spot in the 9th century.

After choosing bathwater, here come the selection of body scrubs and different fragrance of aroma oil for the next treatments. I've experienced many body scrub before, but the Jasmine Rice body scrub at Kaishikiri is one of the best I've tried! The texture is so creamy with sweet soothing fragrance which left my skin so soft and moisturized.


Next, you’ll be directed to the changing rooms so you can get ready for the spa. The facilities are impeccable, from the spacious wooden lockers to store your belongings to a cloth-partitioned private changing space. The counter-lined dressing area has everything you need post-spa -scented powder, spare hair ties, facial cleansers and even hairdryers.
Both girls and guys are given their own yukata - a light cotton Japanese garment worn mostly during summertime. I’ve always longed for the chance to wear one of these gorgeous summer kimonos - who would have thought that my dream would finally be fulfilled here in Bangkok? I was in love with various floral patterns of these charming yuukata, didn't know what to wear. But finally I ended up with a pink cherry blossom pattern - my favorite!


The Private Onsen (45 Minutes)
All the bathhouses at Kashikiri are private - each room contains shower amenities, wicker baskets for dry items and a rustic wooden tub filled with steaming bathwater that’s just perfect for one.
Standard onsen etiquette applies here. First, cleanse yourself at the shower area, soaping up as you would usually do. After rinsing free any remaining suds, make your way to the hot tub.
Tip: Start by sitting on the wooden plank, dipping your legs first. Then, as your body adjusts to the temperature of the hot onsen water, slowly lower the rest of your body in.
The best part about Kashikiri’s private onsen rooms is being able to fully relax in the privacy of your little tub. No stress about having to soak yourself in front of strangers. Swimsuits are even allowed into the bath, a deviation from the strict no-clothes rule upheld by most onsen baths in Japan.
If you’re here in a pair, you have the option of opening the sliding door that conjoins adjacent rooms, so that you can chat with your partner while soaking off the aches of the afternoon.
The Total Treatment (2.5 hrs)
Once you’ve had your time in the hot steamy onsen, an attendant will usher you to a darkened, scent-filled room for the total treatment. I had 30 minute body scrub with Jasmine Rice, then 30 minute body masking with Green tea and almond wrapping, finished with 60 minute aroma oil massage in Lavender oil then 30 minute anti-aging facial treatment.
You can choose to either disrobe or keep your yukata on, after which the masseuse drapes a blanket across you before starting the massage.

One plus is that you can specify which area you’d like your masseuse to focus on. No worries about language barriers - you can indicate all these preferences, including the amount of force used, in the form that you would have filled in the waiting room. The techniques of the therapists, one specialized in body and one in facial treatment were at the top level of skills and sophistication.
This massage was quite unlike any I’ve experienced before; a combination of gliding strokes, circular movements and kneading, which did its job in ridding my body of all remaining tension. I nearly nodded off at several points. They also use a special scented massage oil that doesn’t leave a sticky or greasy residue, so you’re left still feeling clean and fresh afterwards.
All facial massages are performed with Jurlique skincare products. Thanks to theirs natural botanical-based ingredients, my skin felt so much more glowing and healthy after the treatment.
Post-Spa

After a restorative spa experience, you’ll be led back to the cool indoor sitting area, where a tray of complimentary refreshments will be waiting. We were served a trio of brewed green tea, mini swiss roll and fresh cut watermelon.
Some might consider this a minor detail, but I loved how each component balanced and complemented the others. The hot green tea soothes you and makes a lovely pairing with the fluffy, cloud-like white chocolate cream cake, with the crisp, sweet watermelon slices serving as the perfect ending refreshment.
The Verdict
While it does not mimic a 100% authentic onsen adventure, Kashikiri is instead a unique hybrid - combining traditional onsen, private spa and Thai massage all in one package.
Compared to my experiences at the rustic hot springs in Japan, Kashikiri provides a more luxurious and comfortable experience, due to its private spa facilities. Service was incredibly warm, with the spa attendants always alert and ready to assist in a second. Even though they don’t speak much English, they try their best to communicate and meet your needs.
Kashikiri excellent for onsen beginners who would like enjoy a Japanese hot spring experience but can’t make a trip all the way to Japan, or who aren’t fully comfortable with taking on the full-on communal onsen experience. It’s daunting. I’ve been there.
All in all, Kashikiri Onsen is a hidden R&R gem to suss out in BKK, if you’re looking to switch things up from the orthodox Thai massages parlours. I left feeling fully revived and recharged, ready to take on the rest my itinerary.
