This is a really nice topic! I think I'll share it with my student. I saw some tourists from foreign countries wearing rental kimonos and sitting on the street in the photos. They were also eating snacks there! It’s a bit challenging to explain why that’s considered bad manners in Japan. Snacking culture is different, too, right? My parents or caregivers told me to sit when I eat, but not on the road! However, in other countries, it doesn’t seem to matter. And you know what? Every time I eat snacks on the street while standing, I feel guilty... hahaha. Culture is so interesting!
