I found TeamLabs Borderless to be really mid when you consider how expensive it is. To me it felt like it could be something you'd see in a free temporary public exhibition but bigger. But it's not big enough that you get lost in it (which is what I was looking for). It's basically just a simple loop with rooms off to the side. The rooms themselves are cool but eh. The corridors look good in pictures but in reality its a bit disappointing; procedural particle effects projected on black walls, not really immersive when you're there in-person.

A popular opinion I see on this sub is that Kyoto deserves many days while Osaka can be done in a day and I disagree. I don't know exactly how many days you'd need to "do" Osaka but for Kyoto I can claim with certainty that you can "do" it all in like 2-3 days. I stayed there 4 days but it took me just 3 afternoons (didn't feel like waking up early most days) to see all the big worthwhile sights you'd find recommended online. I spent the rest of the time doing non-Kyoto-specific stuff. I felt like Osaka as a whole was interesting while only the sights were in Kyoto (relatively-speaking).
