Six years after a deadly explosion ripped through a spa in Tokyo's bustling Shibuya district, the facility's chief designer was found guilty Thursday of professional negligence resulting in death.
Yoshihiko Tsunoda, 55, a designer-in-charge at leading contractor Taisei Corp., was sentenced to three years in prison, suspended for five years.
Three employees, all women, were killed in the blast at women-only Shiespa in June 2007. Three people passing by were severely injured, including one who remains partially paralyzed.
