While there are many movies a child is the lead, this one is outstanding. You can empathize the children recalling your own childhood. The children here are not necessarily cute. But from this movie, you can see real sensitivity of children who feel social contradiction in their bones.
It is set to Osaka 10 years after the end of the WW2. Japan had been tremendously broken down in the war, but had miraculous recovery after it, thanks to the Korean War. Osaka is a metropolitan which has resumed prosperity and growth.
The noodle restaurant owner in this movie looks poor, but at least they can manage daily life. They and their customers had survived the war, and had worked very hard to resume the life. This couple's attitude to other people around is always warm. They accept the children from the "kuruwa-bune" (prostitution boat) without prejudice. They pay a visit to the husband's former wife at the deathbed and show their son. Everybody had such inherent, pure heart, and those who are left from the rapid economic growth kept it.
