There are some difference between foreign club team and Japanese sports club team such as baseball or basketball for kids.
A big difference is that Japanese club teams do practice a lot comparing with other country’s teams.
For example, baseball team, Japanese club teams have practice on Sunday from 9am to 5pm with one hour break. They keep practicing for about seven hours.
On the other hand, foreign teams tend to consider playing game is more important.
Spending at field for seven hours is not easy for kids but it is not easy for parents who are attendants.
