How are Japanese primary kids like in Class?

Hey everyone, I’m planning to become an English teacher at a Japanese school. The school is not located in Japan, but all the students are Japanese.
The school is primarily looking for a primary school English teacher, and they’ve asked me to give a demo lesson in the near future. While I’m somewhat familiar with Japanese culture and the language, I don’t know much about Japan’s study culture.

I’d like to hear about your experiences teaching Japanese students, like how do Japanese students typically interact with their teachers? Are they active in answering questions, or do they tend to stay quiet? What teaching methods would be most effective in keeping them engaged and attentive in class?

I’d really appreciate any insights you can share!
