Masanori Momiyama, 50, runs a tiny bar on the edge of the slum. He has seen its residents age since he moved here 16 years ago.
“They are the ones who helped to construct many buildings and roads in the 1960s. I think we should thank them,” he said.
He dismisses a common view that the area is dangerous and to be avoided.
“Even though people in this area are quite unique, we are all harmless, friendly people,” Momiyama said.
