Spa World Osaka

Got food poisoning here from one of the restaurants. Ruined my stay in Osaka. Came here to relax and recover from two busy weeks in Japan. The opposite happened. Ended up throwing up all night and being in bed the next two days. Whichever restaurant we went to, it was obvious they didn't like foreigners. That was my first time experiencing this in Japan as normally everyone was very polite when you are polite to them and use some basic Japanese phrases. Really unfortunate. Otherwise the spa rooms were fine, even though a lot was closed off due to construction.

Posting this for my best friend who had a VERY BAD EXPERIENCE at Spa World Osaka. Japan is known to be a safe country—me and my friends come here every year. But for the first time during our trips to Japan, someone from Spa World has stolen from my best friend. He was in the male bath area and placed his belongings, including cash (amounting to over 120,000 yen and 1,000 USD), inside the coin locker. He made sure it was locked, checking it twice. When he came back from his bath, the locker was still locked. However, when he went to pay, to his shock, his pouch was left with only coins—all of his cash was gone. Coin lockers are supposed to secure your belongings while you enjoy the baths. So how could this happen? Even if the coin locker was locked, how did someone manage to open it? Unless, perhaps, someone from inside Spa World was involved since you need a master key to open those lockers. He reported the incident to the police early this morning, September 10, 2025, around 4–5 AM. The police told him that a case like this could take 1–2 years. The management of Spa World also told him they would have to investigate. I am dumbfounded that this happened in Spa World. My friends and I always go there whenever we visit Osaka. I was even planning to go tomorrow, but because of what happened to my best friend, I NO LONGER FEEL SAFE at Spa World. Even if I left my cash in the hotel, what if my phone gets stolen from the locker? Since it seems like someone who works there may have access, how can I bathe in peace? I just hope the management will take immediate action. My best friend keeps crying and has been traumatized by this incident. If anyone has plans to go to Spa World, please think twice. Even the paid coin lockers aren’t safe.

Went to the hot spring last night and left disappointed. I’ve been to spa world before l and had a great experience but yesterday was absolutely terrible. Even though there’s staff cleaning the shower area it was still a mess with people’s used body towels and buckets left on the floor. Also an empty can of sprite was left near one of the baths, why does it not get cleaned straight away? Overall just felt a bit dirty and the construction work killed the vibe. Be aware of the extra late night fee after 12am. It feels like a rip off. As someone who is also half Japanese I felt uncomfortable by the other customers in the hot spring looking at me and showing clear dislike towards me being there too. I wouldn’t recommend coming here.

We were in the hotel annex and it was new and clean. The waterpark was underwhelming with only 2 big slides. The day slide pass was affordable but felt a bit over priced for a hotel guest and only two slides. It was run down and in need or refurbishment. The onsen area I had access to was the European area. Men and women alternate the Asian and European onsen areas each month. There are current renovations in the European area which took out a huge area. Also some of the baths were drained and we couldn’t access them.

The onsen is really nice! But the swimming pool is a rip off. The waterpool slides are pay per use. Up to 1000 yen / ride. Inflatable toys are to rent as well. The only thing you get for admission is the lazy river.
