2 days late: but what a lot of the responses did not mention regarding specifically Japanese tourists:

Most people in Japan get very little Paid time off compared to the rest of the world. And the work culture is so toxic that people get shamed for actually taking their time off. Now, taking that into account, can you imagine that a Japanese person, actually fighting against that, and doing that big trip to a foreign city on the other side of the world, at great expense. They chose Paris for it's reputation. Now imagine their disappointment when Paris is significantly worse than Tokyo.[0] After all the money, time, and precious time off spent to get there, I too would have a mental breakdown under those conditions.

[0] Can confirm. I have been to both. Paris is nice as long as you don't look at the floor. (It is the only major city I've been to that had human shit on the side-walk in the middle of a major tourist area) Tokyo is better in all regards. It's cheaper, cleaner, has more things to do, is better run, etc.
