Spa World

Spa World, Osaka A huge onsen, water park, and entertainment hotel complex in Osaka. There are two full floors of themed onsen, the European 4th floor and the Asian 6th floor. One floor is assigned to one gender for a whole month, then they switch, in May 2026, men are in “Europe” and women are in “Asia”, then they switch again. Each floor has nearly twenty different baths for every taste and color, and that part about color is pretty literal. There are hot, cool, cold, carbonated, herbal, hydro-massage baths, baths with loungers, pretty much everything. Each hall is styled around a different country, whether it is ancient Rome and Greece, Portugal, Persia, or Singapore. Nice! Each floor has a large rest area, towels are free in unlimited quantities, and there is clothing for walking around the common areas. In the European area, after the renovation, a German zone appeared with a huge amphitheater-style sauna and a rich outdoor bath area, three cold baths (18, 15, and 8 degrees) and three hot ones (39, 42, and 47 degrees), utaseyu, and barrels. In the Finnish hall, the saunas and mizuburo stayed where they were. In the Greek hall, yes, in the Greek hall, there are powerful herbal baths, and their aroma can be felt from the neighboring halls. In the Asian area, there were already good rotenburo in stone, also with a stage where you could listen to rakugo, if you happened to come on a day off, but now a tea area has also opened there, and judging by the ads, with cool lighting. On the 8th floor there is a shared water park area in swimsuits, a circular pool, various slides, a kids' area for little ones, and a large warm bath for chilling out. On the rooftop terrace there is an infinity bath with a view of Tsutenkaku Tower and the city as a whole. The terrace used to be paid, but now it is open for free, only the sauna there is still extra, and drinks at the bar are also extra. On the 3rd floor there is ganban'yo and a food court, and a new kids' play area has just opened there, paid, with separate tables for parents on the side so they can keep an eye on their children while eating and drinking. There is also karaoke and other activities. Spa World still offers probably the most varied onsen experience, at least in Osaka, and is definitely a must-visit if you have a lot of free time and money. I have never managed to come here for less than a full day and spend less than a couple of man for a family, taking tickets, food, ice cream, games, and everything else into account. 2026.05.01
