Thinking of visiting Spa World in Osaka, or perhaps you’ve just heard about it and want to know more?
I first visited Spa World many, many years ago with a group of friends who were living in Osaka. At the time, I thought it was such a fun and unusual place. I had only been living in Japan for about a year or so at the time, and there was no social media (I’m showing my age), so the idea of a huge onsen open nearly 24 hours a day with baths inspired by different countries, along with a waterpark, felt completely novel to me.
Fast-forward many years, and I was curious to find out what Spa World would be like now, especially since it recently underwent renovations. Would it still be as fun as I remembered, or had I built it up in my head because I’d first visited when I was younger?
In this article, I’ll share my honest thoughts about whether Spa World is actually worth your time and money to visit when you’re in Osaka, all based on my experience.
If you’re visiting as a family, I have a separate Spa World Osaka with Kids article where I go into the kids’ pools and play areas, height restrictions, and what my daughter thought of everything.
What Is Spa World Osaka?
Spa World is a huge onsen and leisure complex in Shinsekai, within walking distance of Tsutenkaku Tower and Tennoji Zoo.
The main attraction is the onsen, which is split between two themed areas: Spa Europe and Spa Asia. They’re on different floors, with one assigned to men and the other to women. These switch every month. For example, in June women might be assigned Spa Europe while men get to experience Spa Asia. In July, it’s the opposite.
There’s also a waterpark called SpaPoo, a stone sauna area, massages, restaurants, relaxation spaces, as well as a recreation space with karaoke, billiards, darts, and ping-pong, so there’s no shortage of things to do. This is also why some people choose to stay here overnight instead of a hotel (although Spa World does have a hotel as well).
The onsen at Spa World is open from 10 AM until 8:45 AM the following morning, while the main pool area is open from 10 AM to 10 PM.
Keep in mind, though, that costs can go up quite quickly. For instance, you need to pay extra to use the waterpark, and extra for the recreation space. And if you stay past midnight or arrive between midnight and 5 AM, you will have to pay a 1300 yen surcharge as well.
What It’s Like Visiting Spa World
Although I live in Osaka, I had hesitated to go back to Spa World for years because I had heard it was dated and overcrowded. However, a friend told me that it had undergone renovations and was quite nice, so I decided to take her word for it.
The entrance to the building was undergoing more renovations when we visited, and I was pleased to see that the inside of the building looked clean and fairly new. To me, it didn’t look tired and run-down at all, although the locker to place your shoes looked a bit old.
Bring 100 yen coins for the lockers here and for the changing room (you can exchange bills for coins as well).
You don’t need to carry a wallet or credit cards around after putting your things in the onsen changing room locker, as everything you purchase will be charged to your wristband, which you get when you enter Spa World.
My Thoughts on SpaPoo
I first went to the pool, which is called SpaPoo (I know, I know…), and then to the onsen, which is what people typically do when visiting both. Before going to the pool, you need to change into your swimsuit in the onsen changing room and then take an elevator from the changing room to the pool area. (So no, you’re not naked in the pool area, only in the onsen!)
You don’t need to go to the pool, but for me that was the highlight. I originally went because I thought my kid would enjoy it, and I ended up falling in love with the infinity pool at the outdoor Roof Terrace area, which overlooks Tsutenkaku Tower. It is absolutely stunning! Kids under 130 cm cannot use this pool either (although the staff can be a little lax about this rule), and preschoolers and younger children cannot even enter this outdoor pool area. So if you want somewhere quiet, this is it.
I imagine this view would look even more amazing at night when Tsutenkaku Tower lights up!
Note that you may need to pay 500 extra to enter this area depending on the season. There are also tables and loungers that you can rent per hour.
There’s a pool bar here as well, although the drink I got was too watery for my liking. It’s quite pricey too! Despite that, I would absolutely go out to the Roof Terrace again for the view, and perhaps try another drink.
In terms of the indoor pool area, I thought it was way more oriented for kids.
There are two waterslides here that cost 1500 yen for all-you-can-ride or 500 yen per ride: Panic Tornado and ZokuZoku Burn. These water slides use rafts, and you need at least two people for Panic Tornado, so although I bought a pass (which you get from the staff managing the slides), I could only ride ZokuZoku Burn. The slide isn’t extreme or anything, but it was still pretty fun, though, especially since there was no line from the morning up until around noon. Apart from that and the lazy river, though, there isn’t much else for adults to do in this area.
There is also an area called Green Oasis that has a round, onsen-like pool. It’s fairly deep, and the temperature is around 37 to 39°C, so if you want to relax and warm up, this is the place to be. I found there were fewer people here, so it was fairly quiet.
If you don’t care about swimming or water slides, however, I don’t think you need to pay extra for the pool area.
What I Thought of the Onsen at Spa World
During my visit, women were assigned to Spa Europe, which is located on the 4th floor. The men were on the 6th floor, Spa Asia.
Spa Europe has baths inspired by different parts of Europe, including Ancient Rome, Greece, and Capri, along with an Atlantis-themed area and European-style sauna facilities. Each bath has a unique point, such as different minerals or micro-bubbles, that help with restoring your body both inside and out.
It’s cheesy, but I found it fun to go from one area to another and see the differences. For instance, the Atlantis area has actual fish swimming in an aquarium in front of the bath (although the tank was a little cloudy). I did not like lying down in this bath, though, because the water was quite shallow and made me feel uncomfortable having my lady parts exposed.
My favorite baths were the Blue Grotto, Finland, Spain, and Greece. Blue Grotto felt like a little hideaway. Apparently, this bath is meant to help improve your skin texture and your digestion. Finland had amazing bubbles that were so relaxing. Spain had several open-air baths, including one with waterfalls, which I absolutely loved. And lastly, Greece was an herbal bath that smelled so good. Unfortunately, the baths in Greece were a little small so it could get crowded.
My husband went to Spa Asia, and he said he really enjoyed how spacious and relaxing the bathing area was. Spa Asia also has a Japanese-style open-air bath, which gives serious ryokan vibes.
The baths here also come in various temperatures, so if you find one too hot, there is bound to be another that’s just right.
Another thing I liked was that there are standing showers you can use to bathe before (and after) your spa experience, so you don’t need to sit down on a shower chair if you don’t like those.
Towels are provided, and each shower station has body soap, shampoo, and conditioner.
You can borrow (for free) room wear as well, which you can wear while relaxing in the lounge space in the changing room. They come in different sizes and are located in the changing room near the doors leading to the onsen.
What Else Is There to Do at Spa World?
There is a lot to do at Spa World beyond the onsen and waterpark.
World Stone Spa
Located on the 3rd floor, the World Stone Spa is Spa World’s stone sauna area and costs extra. I remember enjoying it when I visited several years ago, but I didn’t use it on my most recent visit because I was with my family. Just like the onsen, the stone spa has themed rooms based on countries around the world. These rooms have different scents and appearances, and best of all, it’s mixed gender, so if you’re a couple, you can visit together. And don’t worry, you’ll be given special roomwear for World Stone Sauna, so no one is naked.
There is also a manga area here, so you can easily spend an hour or more in this area.
Massages and Relaxation Areas
There are massage and body treatment facilities as well, which are on the 3rd floor. Interestingly, the massage shop pictured above offers massages for people who have a stiff neck from being on their smartphones too much!
Karaoke, Billiards, Darts and Ping-Pong
There’s also a Play Spot with activities such as karaoke, billiards, darts, and ping-pong. This is on the 4th floor and is charged by the hour.
Resting Room for Men Only
This is an area where men can relax from 10 PM to 8 AM. I know some people who just sleep here overnight instead of a hotel when they’re in Osaka for a night. Remember that there’s a 1300 yen surcharge after midnight, though! Women can use the relaxation space in the onsen changing room.
Some Common Questions About Spa World
Is Spa World a Good Place for Your First Onsen Experience?
Spa World isn’t a traditional Japanese onsen, but I think it’s pretty low-barrier, and it’s fun to experience all the different kinds.
The bathing rules are the same, of course, but the atmosphere is very different from soaking in an outdoor bath at a ryokan or visiting a smaller local onsen.
Since Spa World is used to international clientele, I think it’s a good place to try an onsen if you’ve never been. Just remember that you have to strip down and be naked in the onsen. No bathing suits allowed, only at the pool area!
What Is the Food Like at Spa World?
The food in the pool area is not good, so I don’t recommend it (although it is convenient).
There are restaurants on the 3rd floor that serve various kinds of Japanese food, but considering Spa World is in Shinsekai, where there are restaurants everywhere, I would rather have a proper meal outside unless I was planning to stay at Spa World for most of the day.
We ended up eating kushikatsu at Kushikatsu-Oji after leaving, which everyone enjoyed considerably more.
How Much Does Spa World Cost?
Basic admission, which includes the onsen, costs 1500 yen on weekdays, while using the pool is an extra 500 yen on weekdays and a whopping 1200 yen extra on weekends and holidays.
There are then various optional extras inside, including the large water slides, stone sauna, massages, some recreational activities, and certain seating areas.
This means the final cost can be quite a bit higher than the basic admission price if you want to do everything.
We went on a weekday, and for me alone it cost 3500 yen, which I thought was pretty decent for the pool, all-you-can-ride waterslide, and the onsen, especially since we were there for six hours. This doesn’t include food or drinks, though.
I think next time I will try to go to the World Stone Spa.
How Long Should I Expect to Spend at Spa World?
We were at Spa World for around six hours during this visit, but keep in mind we were with a kid, and with kids, everything takes a little more time than expected.
We spent roughly three hours at SpaPoo and around an hour in the onsen, with the remaining time spent eating, changing, and using other parts of the facility. I would have gladly spent perhaps another 30 minutes to an hour in the onsen, but my kid was getting antsy, so we left.
I think if you don’t have kids, three hours might be enough if you go to the pool. If you decide to go to World Stone Spa, I would add another hour to your visit.
When Is the Best Time to Visit?
We arrived at around 10:30 AM on a weekday, and I’m glad we went early because although there were several families there, the pool was still fairly quiet, especially compared with around noon when noticeably more people started arriving, and the lines for the waterslides started to get long.
By the time we made it to Spa Europe in the afternoon, it was fairly crowded. So if you want an onsen experience with hardly anyone there, the earlier in the day, the better.
Do I Need a Bathing Suit for Spa World?
If you’re using the pool, you need a swimsuit for Spa World. You can rent a swimsuit for 650 yen. Men’s sizes range from M to 4L, women’s from size 7 to 17, and children’s swimsuits are available from 90 to 150 cm. A refundable deposit is also required.
You can also purchase a swimsuit from the store in Spa World.
Is Spa World Good for Kids?
I think Spa World is great for kids! My daughter had an absolute blast there, and she didn’t want to leave. For more details, including kid-friendly areas not covered in this piece, read my article on visiting Spa World with Kids.
So, Is Spa World Osaka Worth Visiting?
I think it’s definitely worth checking out Spa World when you’re in Osaka, but of course only if you’re okay with being in your birthday suit around strangers.
Before going back, I genuinely wondered whether Spa World was something I’d enjoyed mainly because I was in my twenties and everything about Japan still felt new to me. But I still had fun all these years later, although perhaps it’s because I didn’t go with huge expectations.
I don’t think of Spa World as a beautiful traditional onsen in Japan; it’s gimmicky, not particularly massive, and I certainly wouldn’t go for the food. I’ve also heard it can be crowded on evenings, weekends, and holidays, so you might want to avoid those periods.
But if you want an enormous, slightly over-the-top place where bathing, swimming, and entertainment are all mixed together, then Spa World is absolutely worth checking out.
According to my Japanese husband, “I think it’s a good place to relax. I don’t know if I would recommend the pool other than the infinity pool. For me, the onsen was the best part. It’s a good place to kill time or if you need somewhere to stay at night since it’s open almost 24 hours, especially if you’re drinking in Shinsekai, miss the last train, and need a place to crash.” (Spoken like a true salaryman.)
I think Spa World is definitely unique for someone visiting from outside Japan, and I certainly felt relaxed afterwards. And as someone who lives in Osaka, the view of Tsutenkaku from the rooftop infinity pool alone makes me want to go back ASAP!
