I was pretty confused about what to do at one point. I bought a water from a 7/11 while walking around in Tokyo and didn’t know what to do until an old lady it a subway market (also kind of wild) took it, washed it, and put it in her backpack when I gestured for the trash.
I was amazed there weren’t public trash receptacles when I was there (I was only there for a couple days though, maybe I just missed it).
You didn’t. Japan doesn’t have public trash cans.
