You cannot dance in Japan after midnight. This rule is sixty years old. This rule tried to stop crime.
Now the situation is changing. Now you can dance in clubs until morning. However, there are some rules. There must be light in the club. If there is light, people do not do bad things.
Difficult words: midnight (12:00 AM, the beginning of the new day), rule (rules tell you what you can or cannot do), crime (something you are not allowed to do).
