TOKYO (TR) — Tokyo Metropolitan Police have arrested the 49-year-old president of an IT firm in Minato Ward on suspicion of dumping the corpse of a missing executive at the firm.
The apprehension took place despite the victim’s body remaining undiscovered, reports TBS News Dig (April 17).
Katsuya Mizuguchi, president of the Akasaka-based IT company Linux Japan, is accused of removing the body of the male board member from the company’s office and disposing of it sometime between October 5 and 6 of last year.
In commenting on allegations of abandoning a corpse, Mizuguchi said, “I didn’t do it.”
Missing since last September
According to police, the victim, aged in his 50s, went missing on September 28, 2025. The investigation was launched after a female acquaintance of his grew concerned and consulted with authorities on October 10.
Although the body has not yet been found, an on-site forensic inspection of the company’s office revealed multiple bloodstains matching the missing executive.
Police have established a special investigation headquarters. Authorities are now probing the case with a view toward a murder charge, suspecting the executive was killed inside the office before his body was discarded.
Linux Japan
According to the company’s website and credit rating agencies, Mizuguchi worked for an IT-related company after graduating from university. He has authored nearly 10 books, including introductory guides for becoming a systems engineer.
In November 2009, he founded Linux Japan and became its president. The company develops systems and network servers, conducts seminars and dispatches its own engineers to clients. According to police, it has approximately 30 to 40 employees.
According to residents near the company’s office in Akasaka, where the incident occurred, investigators, wearing plastic gloves and hats, conducted forensic work earlier this month. Prior to that, they had also collected security camera footage from nearby locations.
A woman living nearby told Jiji Press (Apr. 18), “I didn’t even know the company was there. The Akasaka Imperial Palace is nearby, and patrols are frequent. It’s not the kind of place where something like this would happen.” Another woman, appearing frightened, said, “I didn’t notice the incident. It’s scary that something like this happened so close by.”
