Mr. Isamu Sasayama, a former resident of Hashima Island

You got to be kidding! I shudder at the thought of these sorts of things even being a possibility.

"Born December 25th, 1925, in Nagasaki City; moved to Hashima Island when he was at the age of six and has lived in Building No. 30, No. 17, and No. 65.
After graduating from Hashima Elementary School in 1941, he joined the machine tool division of the former Mitsubishi Materials Corporation (三菱礦業機械工作課). He worked at Hashima Coal Mine and Takashima Coal Mine until their closure. Mr. Sasayama was a devoted Catholic and often held mass at his house in Hashima Island. Such episodes were also interviewed by NHK TV station."
