School Life in Japan

This time, We will introduce "School Life in Japan" with two sub-themes.
One is "cleaning." It is a unique culture in Japan where students clean their own classrooms after class. What background and educational purposes lie behind it?
The other is "club activities." Enjoying youth with friends through club activities is fun, right? I believe this is similar in both UK and Japan. But are there subtle differences between the two?
After our introduction above, we would like to discuss the similarities and differences in school life between UK and Japan. Please join us.
