Aug. 21 (UPI) -- Japan early Friday executed a 58-year-old man convicted of killing five people in a fire he ignited at a pachinko parlor in Osaka 17 years ago, the first death-row inmate to be put to death by the ultra-conservative administration of Prime Minister Sanae Takaichi.

Sunao Takami was hanged to death early Friday, Justice Minister Hiroshi Hiraghuchi told reporters at a press conference, Jiji Tsushinsha news agency reported.

"I ordered the execution after a very careful consideration."

Hiraghuchi signed the execution order Tuesday.
