On a sauna trip, the sauna is the star of the show — shopping and splurging in the entertainment district come second. I'm walking through Shinsaibashi, one of Japan's finest entertainment districts, but my destination is neither a restaurant nor a shopping mall nor a soapland. It's a sauna.
I walked through Shinsaibashi shopping arcade and arrived in front of the building housing Osaka Sauna DISSE. On my way to the elevator, I ended up alongside a pair of blonde guys who looked like hosts. They wore the exhausted expressions of men who had spent the whole night charming women. I found myself thinking that once they got into the sauna, they'd be refreshed and ready to start a new day — and while I was busy thinking about other people's business, we arrived at the 4th floor.
The moment I stepped off the elevator, I knew this was going to be good. First, the scent was incredible. A woody aroma drifted throughout the entire facility. I was already looking forward to how the sauna room itself must smell. The staff were full of energy too, greeting me with a cheerful warmth that made me think: let's do this.
Before heading to the main bath area, I checked the facility information. Osaka Sauna DISSE has six different saunas: River Sauna, Forest Sauna, Water Surface Sauna, Hanare Sauna, Tea Room Sauna, and Garden Sauna — each with its own distinct concept. There are four cold plunge baths, set at 16°C, 15°C, 12°C, and 8°C respectively. The relaxation spaces are equally well-equipped. This is truly a facility built for sauna lovers. My excitement was at maximum as I headed to the changing room for what promised to be an extraordinary sauna experience.
As always, I stripped off my clothes at lightning speed and entered the bathing area. In an instant, I had the sensation of being warped into another world. A dark, modern space filled with the scent of aromatherapy — it exuded a sense of luxury. First, I rushed to get the lay of the land: where were the six saunas, and was the flow from sauna to cold plunge bath smooth? Perfect. Then I drew up my plan for the sets — I needed to understand each sauna's character and map out the sequence that would bring my body to its peak condition.
After careful deliberation, I decided to start with the River Sauna. It's the largest of the six saunas at Osaka Sauna DISSE, and also the most distinctive — but I'll explain that in a moment. The River Sauna has two sauna stoves, and the pleasant scent of wood fills the room. The BGM from the drama Sa-do playing in the background was a perfect touch. There's no TV in the sauna room, so I slowly closed my eyes and stilled my mind. A stretch of pure emptiness followed, and I worked up a serious sweat. Time for the cold plunge.
I mentioned earlier that the River Sauna is the most distinctive of the lot. Here's why: there's a cold plunge bath inside the sauna room itself, and it connects to the cold plunge bath outside — you can dive under and swim through to exit the sauna room without ever opening a door. It's a cold plunge bath built inside the sauna. In all my years visiting sauna facilities, this was the first time I'd ever been able to leave a sauna room without opening a door.
For my second set, I headed to the Forest Sauna. This is Osaka Sauna DISSE's hottest offering — a high-temperature steam sauna. Steam saunas are typically set around 60–70°C. But the Forest Sauna here was 93°C. I had never been in a 93°C steam sauna before. The moment I stepped inside, I was assaulted by a ferocious blast of steam. The room has three tiers, but there was absolutely no way I was making it to the top. The first tier was all I could manage. Even a dry sauna at 93°C would be considered hot, but with steam added, the humidity skyrockets and the heat feels overwhelming. I hit my limit in five minutes and plunged into the drum-can cold plunge bath. The contrast of plunging from 93°C scorching steam into 12°C ice-cold water delivered a sensation of pure bliss. And this was only my second set — yet I blanked out on a chair for about ten minutes.
For my third set, I headed to the Water Surface Sauna. This is a steam sauna where you can recline in a semi-lying position on gently curved benches. As I lay back gazing at the ceiling, soothed by the pleasant scent of herbs, the surface of the cold plunge bath beside the sauna room reflected light upward, creating a shimmering effect on the ceiling above me. A comfortable temperature, the scent of herbs, a dancing shimmer on the ceiling — a sauna that stimulates all five senses. I pressed my hands together and offered a prayer: may this wonderful sauna journey continue for a long time to come.
For my fourth set, I headed to the Hanare Sauna. Hanare means detached room, and true to its name, this small sauna room — where you can do self-service löyly, lie down, and where whisking sessions are also held — sits quietly tucked away at the far end of the bathing area, perfectly fitting its concept. The interior is dim, making it ideal for meditation. Since no one else was using it, I stretched out on the upper bench. Lying down in the sauna allows the heat to warm your body evenly. The gentle heat stimulated my body, and even as I sweated heavily in the intense warmth, the pleasure easily outweighed the discomfort. I think it's the perfect balance of temperature, humidity, and scent that makes it feel that way.
After the cold plunge, I lost consciousness again in the relaxation area. Time for the last set.
For my fifth set, I headed to the Tea Room Sauna. True to its name, it's a sauna themed around a traditional Japanese tea room, with tatami flooring. There are no benches like in a typical sauna — you sit cross-legged on the tatami and focus your mind. The most unique feature of the Tea Room Sauna was the enormous teapot sitting on top of the sauna stove. It's filled with tea, designed to drip slowly onto the sauna stones, generating a constant stream of tea-scented steam that is deeply soothing. Sitting naked in a beautiful tea room and sweating profusely — this act of near-sacrilege becomes oddly addictive. I enjoyed the Tea Room Sauna to my absolute limit before diving into the cold plunge.
After finishing five sets, I was a complete empty shell. I lay down in the rest room next to the changing area and couldn't get up for quite a while. I'm not sure how long I was out. I came back to consciousness when hunger hit — the most human of physiological signals.
After reaching the perfect state of totonou in the sauna, it's time for a good meal. You could even say that this is the moment I go to the sauna for. I moved to the dining area inside the facility and ordered house-made chashu rice bowl, Finnish-style vegetable soup, and ginger pork. Eating whatever I want, as much as I want — on a trip, I live true to my own desires.
After a short wait, the food arrived. I started with the Finnish-style vegetable soup. It soaked deep into my body, hollowed out by the sauna. Delicious. Then I alternated between the house-made chashu rice bowl and the ginger pork. A perfect loop had formed: Finnish-style vegetable soup → house-made chashu rice bowl → Finnish-style vegetable soup → ginger pork. Just like sauna → cold plunge → rest. Osaka Sauna DISSE hadn't just taken over my body — it had taken over my stomach too. I love this place.
On my way out, I ended up in the same elevator as the two host-looking guys I'd arrived with. When they'd walked in, they'd looked completely drained — but now they looked like different people entirely, bright-faced and refreshed. One of them said, that was incredible, and the other replied, seriously the best — that'll keep me going for a while. I believe the sauna has the power to turn your life around.
Leaving Osaka Sauna DISSE behind, I drove out to Higashiosaka to head to my next destination. There are several great onsen and sauna facilities in Higashiosaka too, but tonight I've decided to visit Naniwa Kenkoland Yu-topia. The Osaka sauna journey continues.
