Back in 1990, while taking a stroll along the Tama River, photographer Osamu Konishi came upon a surreal scene: dozens of cats sitting amicably and quietly on the branches of a tree, almost like apples waiting to be picked, as well as on the ground below.

When Konishi went home and told his wife, Michiko, she didn't believe him. So he took her to the spot the next day to see for herself, except this time there was a man feeding the strays.

They decided to help him.
