3D walkthrough of Japanese bathhouse complex / international bathing culture

I was able to visit an enormous bathing complex in Japan earlier this year and was struck with how different the communal bathing cultures are between there and America. I stumbled on their website's immersive 3D walkthrough recently and thought others would be interested to see the whole process. It starts off in the lobby to purchase tickets, and you can walk thru the social areas, and then the single-sex nude areas like the locker rooms, wet sauna, and even the outdoor area.

This bathhouse was smack dab in the middle of a major shopping mall, and connected to a stadium and amusement park. There were signs everywhere for the bathhouse, and based on the constant stream of people going in and out during my time there, it was probably expected that anyone at the mall, amusement park, or out for a day of shopping would very likely also unwind at the bathhouse before heading home.

If you just look thru the men's side, you can see that there are dozens of rows of lockers that looks like lockers for over 600 men at a time, brightly lit and very open to the locker hallway.

And the bathing area itself is enormous with very large saunas and pools. The outdoor area was also an awesome experience and it was refreshing to alternate between the sauna, the hot baths, and then walk around in the icy cold air to cool off. It's hard to see here, but the outdoor area was also open (with some slats) to the shopping mall below so you could people watch or see a roller coaster flying by every 10 minutes.

I was really struck with how different the bathing culture was. You'd see families, groups of friends, people leaving the concert at the stadium, all heading over the baths. And the men were totally non-self conscious about nudity in a way that was totally alien coming from America. In the lockers, there were no "towel dances", or rushing to get back into clothes. Guys would take their time at the lockers while talking with their friends, and nobody bothered with towels when walking from the lockers to the baths. And in the baths themselves guys would sprawl out on the chairs or even nap on the benches all while a constant stream of others walked by.

This was just totally different than home even at the K-Spas I've been to. Has anyone else been to enormous bathing complexes like this in Japan or Asia? What was your experience?
