The company will organize a trip to Japan next month. Is there anything to pay attention to?

Maybe I'll tell you everything if I join the group, okay? Japanese garbage classification, there are no trash cans on the street, I collect garbage myself, and walk on the left. Smoking is forbidden in almost all public places, so smokers should pay attention. Smoking is allowed only in designated places, but not in other places. Prepare a pocket coin with small change. Everything else is convenient. There is nothing to pay attention to.
