Tennen Onsen Naniwanoyu

I visited Tennen Onsen Naniwanoyu on a weekday night, and it ended up being one of the most relaxing experiences of my trip. If you’re in Osaka and craving a soothing soak after a long day, this onsen is absolutely worth a visit, especially on a chilly evening. The highlight for me was definitely the outdoor onsen. The combination of cold night air and warm natural spring water was perfect, creating that cozy contrast you only get from a good open-air bath. I especially loved the carbonated outdoor “beauty bath”, which felt incredibly gentle on the skin and made the whole experience even more rejuvenating. They also offer a sauna and a cold plunge, so you can enjoy the full warm-cold cycle if that’s your thing. One small regret: I didn’t get to try their body scrub service because all the slots were fully booked. So if you’re interested in add-on treatments, definitely book early or ask as soon as you arrive. A few practical tips for first-timers: • Bring your own towels. They don’t provide them, and rental costs about 150 yen for a small towel. • They have lockers available to keep your belongings secure. • Basic shampoo, conditioner, and body wash are provided, so you don’t need to pack your own unless you prefer specific brands. Overall, Tennen Onsen Naniwanoyu offers an affordable, relaxing, and authentic Japanese bathhouse experience right in the city. Perfect for winding down and treating your body after a long day out. I’d happily return for another soak—especially that outdoor beauty bath! ♨️✨

For westerners - U.S, Canada, Europe, and Australia/New Zealand This place makes you pay for towels and other amenities. They only provide body soap, not even a scrub. I would not recommend this place. It ruined the experience for me. I will never come back here again. Everything about this place sucked. It's not a vibe at all. They don't even have a women's lounge, don't provide clothing to walk around in. One of the worst onsens I've been to so far. Charging for towels is insane to me! There are far better onsens that provide all amenities for an affordable price.

Located in a commercial building on the top floor (do not enter the first floor like us and land up in a gaming/gambling parlor) This place is a great Onsen with 5 indoor pools, 2 saunas , 2 outdoor pools, 3 individual bucket pools and a bunch of resting areas. Had a very relaxing experience. The outdoor area opens up to the sky with a pleasant natural breeze and views of airplanes flying over. Entry fee was 1000 yen that you need to pay at kiosks when you enter. Photography indoors is not allowed for obvious reasons. The locker rooms are clean and well maintained

Located at 8th floor, premises is clean and well organised, separate locker for umbrella, shoes and personal belongings. I came at around 11.30 am and there was no crowd in onsen, the weather was little cloudy and it was really amazing to enjoy sauna and hot bath on top floor under the view of open sky. Other facilities like massage and scrub is also available. The price of onsen for adult is JPY 1000 only with additional charge for towel and other things which is very nominal. There is a restaurant as well where i tried octopus wasabi which was good.

Great onsen on the 8th floor of the building. Shoes taken off on entry to a large common space with restaurants and vending machines. Vending machine is straightforward and locker system is simple. Indoor and outdoor baths at differing temperatures and jet pumps. Dry and wet sauna inside with showers for rinsing and a cold plunge bath too. Outdoors there are a few individual tubs and regular baths as well as places to lay with and without water. Enjoyable experience and returned twice however note that tattoos are not permitted.
