Gyoza no Ohsho Acquittal: Court Clears Man in 2013 Shooting

The Gyoza no Ohsho acquittal came on Friday, October 16, 2026, when the Kyoto District Court found Yukio Tanaka, 59, not guilty of murdering Takayuki Ohigashi, the president of dumpling chain operator Ohsho Food Service. The verdict closes the courtroom chapter of one of Japan’s most famous unsolved crimes, while leaving the question of who killed Ohigashi unanswered.

What the Gyoza no Ohsho acquittal means for the case

Tanaka, a senior member of a gang affiliated with the Kudo-kai organized crime group, had faced a possible life sentence over the gangland-style killing. Prosecutors argued he shot Ohigashi dead in the early hours of December 19, 2013. The defence maintained throughout that Tanaka was not the culprit, and the court has now agreed that the evidence was not strong enough to convict.

The 2013 killing of Takayuki Ohigashi

Ohigashi, then 72, was gunned down in the parking lot in front of Ohsho’s headquarters in Kyoto’s Yamashina Ward before dawn on December 19, 2013. The brazen shooting of the head of a nationwide restaurant chain shocked Japan, and as months turned into years without an arrest, the case grew into one of the country’s most captivating unsolved crimes, mentioned alongside the 1980s Glico-Morinaga corporate blackmail case and the 2000 Setagaya family murders.

A breakthrough appeared to come in October 2022, nearly nine years after the killing, when Tanaka, who was already in prison over an unrelated case, was arrested in connection with the shooting. He was charged with murder and violating Japan’s firearms and swords control law.

The verdict and the reaction in court

According to Sankei News, when the presiding judge read out the not-guilty verdict, Tanaka nodded several times and bowed his head toward his defence team. The Kyoto District Court’s ruling rejected the prosecution’s demand for a life sentence. Yahoo! News and the Asahi Shimbun both confirmed the acquittal within hours of the ruling.

How the trial reached the Gyoza no Ohsho acquittal

The trial, which began in late 2025, was defined by unprecedented security and a prosecution case built entirely on circumstantial evidence. There was no direct evidence tying Tanaka to the shooting, and no confirmed motive, with no known link between Tanaka and the victim.

A case built on circumstantial evidence

Prosecutors leaned heavily on a cigarette butt found near the crime scene, arguing that DNA on it matched Tanaka and showed little deterioration, which they said indicated it had been discarded shortly before the shooting. They also presented video footage of a person of similar height, build and gait near Ohigashi’s house the day before the murder.

The defence countered that the cigarette butt was unlikely to have been smoked on the day of the killing and suggested it had been left at the scene by the real culprit. It also raised the possibility of an alibi, arguing Tanaka may have been in Fukuoka Prefecture, in southwestern Japan, on the day of the shooting. The court found this accumulated circumstantial picture insufficient to prove murder beyond a reasonable doubt.

Why the trial had no lay judges

In a highly unusual move, the case was tried solely by professional judges after the Supreme Court rejected the defence’s request for a lay judge trial. Prosecutors had argued that lay judges could face intimidation or threats, given that the Kudo-kai is a legally designated dangerous yakuza syndicate based in Kitakyushu with a reputation for targeting civilians. Spectators at the Kyoto District Court passed through metal detectors, and bulletproof glass separated the gallery from the proceedings.

What happens after the Gyoza no Ohsho acquittal

The acquittal does not necessarily end the legal story: prosecutors may appeal, and if they do, the fight over the circumstantial evidence will move to a higher court. Either way, the mystery of who shot Takayuki Ohigashi remains, and the case returns to the ranks of Japan’s great unsolved crimes.
