This question may sound weird since I'm not Japanese, but I'm posting it anyway.
The school is starting again soon, and I want to greet my teacher like they do in Japan. What should I say and do?
If its the morning, use the traditional ??(Aisatsu- a greeting) by bowing and saying ???????? (Ohayou Gozaimasu).
You could also say "??????” (Onegai-shimasu) which translates to "Please". It translates to a greeting in that context.
