Japanese football fans are famous. After World Cup games, they clean the stadium. They pick up trash in blue bags.
People around the world like this very much. But now, there is a big debate in Japan. Many women are angry about this.
They see a big problem at home. On social media, people share photos. One photo shows a man cleaning at a stadium.
He looks very helpful and kind. Another photo shows the same man at home. He sits on the sofa with his phone.
His wife does the dishes. She also does all the laundry. Data shows that Japanese men do very little housework.
They spend only 47 minutes a day on chores. But Japanese women work many hours at home. In families with small children, mothers work seven hours.
Fathers work less than two hours. Some people say the fans are not honest. They say it is easy to clean for cameras.
It is harder to help at home every day. Some people say big events in Japan are still messy. This means the fans only clean for people abroad.
Other people defend the fans. They think cleaning is a good part of Japan's culture. Fans from other countries now copy the Japanese fans.
People want help in the stadium. But women also want help in the kitchen.
