I was just there earlier this year and I saw no foreigners, no graffiti, and no crime. However it is true that a lot of touristy areas are being completely overwhelmed and tourists are leaving trash everywhere. It was absolutely disgusting in Osaka at one of the big street markets
Japan's relationship with trash is a strange one. The country does not have public trash cans anywhere on the streets. You are not supposed to have public places to put trash there. Japanese people pack their trash up and take it home and dispose of it at home if they have been outside and generate trash. It's extremely fucking weird and I'm not surprised tourists have no fucking idea what they are supposed to do with their trash. Most tourists just leave it somewhere discreet, which is why bathrooms in touristy areas of Tokyo have random trash left in them. Tourists are baffled by the lack of trash cans in the country and Japan needs to address it by having public trash cans, at least in tourist areas
Comparing Tokyo to any Western capital is hilarious though. Tokyo's streets are clean, there is no crime, and there are no homeless anywhere I could see and I went all over the city riding the trains which were perfectly clean and perfectly safe. During Japan's commute hours, you really are elbow to elbow with the other people on those trains and not one single person got pickpocketed, robbed, stabbed, or shot. Japan has a lot of problems, almost all of which are caused by their inexorable population decline, but comparing Japan to the West is the epitome of retard Youtuber nonsense
