It says that the average number of hours of sleep among Tokyo workers is just six hours.  東京の労働者（会社員など）の平均睡眠時間は6時間だそうです。

In small groups, it might be interesting to talk about how much you sleep now, how much you slept when you were younger, how much you would like to sleep, and how much sleep you think is ideal.  少人数のグループで今とのぐらい寝ることができているか、高校時代やその前にどのぐらい寝ていたか、できればどのぐらい寝たいか、また、どのぐらいの睡眠が理想だと思うかについて話し合うといいかもしれません。
