No they’re there, however there aren’t trash bins once you leave the food vendor. So people just finish eating and dispose the trash there. Even if it’s a food truck, you can hand your trash back to the staff.

If it’s for carry-out, people will pack their trash for disposal at home (you’ll see a ton of people walking around with backpacks and totebags).

Yeah for this reason, you don’t see this culture of eating/drinking while on-the-go in Japan lol. It’s too inconvenient.
