Green Jail

by HUANG Yin-yu

Grandma Hashima is the final person still alive and can tell the stories of “Green Jail, the notorious coal mine in which 3,000 colonial miners were imprisoned before World War II in Okinawa, Japan.

What has happened in the coal mine? Her adoptive father Yang Tien-fu was the head of Taiwanese miners who recruited hundreds of miners to this “Green Jail”, making them unable to get back to Taiwan and leave the jail… Is he an assaulter or a victim under Japanese Imperialism?

Grandma is 93-year-old now, alone keeping those secrets. It is the final years of her life, a survivor with the memory of crime, pain, anger and the miserable history throughout 80 years.
