There are no public trashcans in Tokyo and mostly throughout Japan as well. This is a result of the Tokyo bombings in the mid-90s, which resulted in a ban on public trash bins. This obviously forces you to have to carry your trash with you to the next available trash bin, which you likely will find at your destination, be it work or a store.
Places in the UK got rid of garbage cans because of IRA bombings or whatever. So it became normalized to just drop the trash everywhere. In the nice places they have people constantly walking around picking it up. And in other places, they don't.
What I really want to know the revolutionary solution to is laundry. We can't all have our own washing machine but communal facilities are soooooo annoying. I tried handwashing by some methods I found online but they did not work at all.
Once I thought my landlord shit in my home but it turned out to be a racoon.
