I gained this idea from the internet which show some pictures about Japanese people‘s daily life .They work very hard until they do not have time to prepare their own meal. So, they often have their meal at the restaurant after working. Normally, they have their meal at the restaurant which located near the train station because this is convenient for them to take train back to their home. Besides, they often buy the bendo (ベンド) at the convenient shop before they go to work. So that, they can have bendo (ベンド) during lunch time. By doing so, they can save their time to work.
Japanese people slept less hours every day. They want to spend more time to work rather than sleeping. As a result, they fall in sleep in the train easily. I have seen a picture from internet which show a Japanese man can sleep in the train even standing. So, I believe this is the result of the heavy workload of the day.
Besides, Japanese student are work very hard no matter in academic or in club activities. Once they have involved in club activities, they will work very hard to practice and achieve goal in competition. I gained this idea from the Japanese drama-1 liter of tears. The main character-Aya kito is a secondary student. She is the leader of her school basketball team and the director of the choir team in her school. She worked very hard to do choir practice with her friends. Finally, they performed a great show in the graduate celebration.
