Seriously though, Japan has the best toilet infrastructure in the world as far as I can tell, in terms of maintenance and quantity. Tourists don’t shit in people’s gardens in other countries as much, or at least it doesn’t get scandalized. I assume it doesn’t happen all that often here either, probably those were 1-2 cases that get hyped up. But toilet infrastructure is really the last thing you have to worry about.

Also, it’s not like all of a sudden 1000 people spawn in the same spot and all have to take a shit within the next 2 minutes. I expect tourists, especially adults, to be able to plan their dumping schedule at least 10 minutes ahead in regular times. If there are a few emergencies, the Japanese toilet infrastructure can accomodate for them. There are not 1000 emergencies at the same time. Just walk for 2 minutes or across the street to the next convenience store and take a shit there.

Other than that, the star architect toilet tour through tokyo is one of my recommendations for friends coming to visit. It’s really an experience!
