A documentary that is closely tied to "Kodomonosato," a playground that has served Kamagasaki, Nishinari-ku, Osaka, known as the "city of day labourers," as a place for kids to unwind for 38 years. No matter their disabilities or countries, "Kodomonosato" admits kids from 0 to 20 years old for free. It serves as a bustling gathering spot where parents and children who are temporarily away from home can unwind. It shows the trials of young people who overcome obstacles to become strong adults, the staff members who help them, and city dwellers.
