Alright, let's go to Kumamoto. That thought struck me on December 26th, right in the middle of what would be my last day of work for the year.
I finished work at 3:30 PM. With the year-end holiday season in full swing, I was worried about bullet train availability and hotel vacancies. I checked the Shinkansen reservation status on my computer and found that there were a few seats left. But I live in Tokushima Prefecture. Given the train schedules, boarding at Shin-Osaka Station would be the smarter move. It takes anywhere from two to two and a half hours to get from home to Shin-Osaka. If I left home at 4:00 PM and arrived at Shin-Osaka around 6:30, that would still be another three hours to Kumamoto...
There was no point overthinking it, so I just got in the car. I headed toward the Kansai area and started putting a plan together along the way. If I pushed through to Kumamoto today, even by the most optimistic estimate I wouldn't arrive until around 10:00 PM. What could I even do at that hour? I make it a point to be in bed by 10 or 11 PM every night, so arriving that late would almost certainly mean sleep deprivation. And you simply cannot enjoy a sauna to its fullest when you're running on empty. If all I'd be doing is arriving and crashing for the night, there was no real point in going to Kumamoto today. The better call was to spend tonight at a leisurely pace in Osaka, then head to Kumamoto early the next morning and have a proper sauna session. And so, I decided to stay in Osaka for the night.
Around 6:00 PM, I parked near JR Nishinomiya Station and pulled up my phone to book a hotel. I already knew exactly where I wanted to stay. There was a sauna facility at one particular hotel that I had been wanting to visit for quite some time — the Hanshin Sauna at Hotel Hanshin Osaka. There was a vacancy, so I booked it on the spot and headed straight there. It's a 15-minute walk from JR Osaka Station. The hotel's large building came into view, and I passed through the elegant lobby to check in. My room was on the 17th floor. The moment I stepped inside, a sweeping night view of Osaka spread out before me through the large windows. Despite the last-minute booking, landing such a nice room felt like a stroke of luck.
Now, on to the long-awaited Hanshin Sauna. I took the elevator down to the dedicated floor and found the entrance. Hotel guests can use it for 800 yen. I paid and headed to the locker room. The lockers themselves felt upscale, and the place was pleasantly quiet. The luxurious atmosphere made the whole experience feel that much more special. I hydrated at the water dispenser near the entrance, then stepped into the main bathing area. Right away, I spotted the sauna room with its beautiful floor-to-ceiling glass windows. The high-ceilinged, open space featured an indoor bath with natural hot spring water, a bubble bath, and a cold plunge bath. Outside in the open-air section, there was a rock bath and two chairs for cool-down relaxation. It wasn't a large facility by any means, but the compact, well-thought-out layout made moving between areas feel wonderfully smooth.
After rinsing off, I eased myself into the natural hot spring known as Tokujiro no Yu. The gentle, silky feel of the water seemed to wash away an entire year's worth of fatigue. Once I'd warmed up sufficiently, I made my way into the sauna room. The air felt slightly on the dry side, but I settled in and let the heat slowly work its way through my body. The pleasant scent of wood and the enveloping warmth coaxed sweat from every single pore. There was a TV inside the sauna, though the volume was kept low — a setup that works just as well for someone who wants to catch a show as for someone who wants to sit in quiet meditation.
After the sauna, I moved to the cold plunge bath. I submerged myself in the deep tub, which fits about three people. The water temperature was a perfect 15°C. With so few people around, I could stretch out fully and just relax. After the cold plunge, I headed outside for some cool-down time in the open air. Breathing in the Osaka night, I found myself reflecting on the year. I had managed to visit so many different facilities this year. Around August, I started seriously touring saunas across the country, pouring whatever time and money I had into sauna travel. I visited places I'd never been to before, week after week, and I feel like those experiences genuinely added depth to my life. Throwing yourself completely into something you love — that's the most important thing for building a happy life. I felt that truth more clearly than ever. In the end, the one who makes the most memories wins. In that sense, 2025 was a perfect year.
I lingered in that self-satisfied afterglow, cycling between the open-air relaxation, the natural hot spring, and the sauna. Five rounds in total. Sauna, cold plunge, cool-down. This loop saved me again this year. Thank you. I wrapped up tonight's session in a state of perfect totonou and returned to my hotel room. All that was left was to sleep soundly and catch the 7:00 AM Shinkansen to Kumamoto in the morning. The time had finally come to visit Yurakusu — the sacred sauna of the west.
