The Yamaguchi District Court sentenced a 31-year-old man on 30 October 2026 to three years in prison and a fine of 500,000 yen for confining two men in Shimonoseki and for possessing cannabis for profit, among other offences.[1] Prosecutors had sought five years in prison and the same 500,000-yen fine, and the court imposed a prison term it did not suspend.[1] He was convicted of arrest and confinement and of violating the Narcotics and Psychotropics Control Law.[1] In December 2024 he conspired with another man to seat two men, then 19, in chairs in a flat in Shimonoseki and tie them with rope so they could not escape.[1] Police arrested three men over that confinement on 2 March 2026, and the two victims had freed themselves on 29 December 2024 and reported it to police two days later.[2] Police said the episode began on 28-29 December 2024 in Hiroshima City, where the victims were put in a car, one was punched in the face repeatedly and both were blindfolded before being tied up at the Shimonoseki flat.[2]

In October 2025 he held about 172 grams of cannabis for profit in a flat in Shimonoseki, and late that month he used cannabis in the city.[1] Presiding judge Yasuyuki Mizota called the confinement malicious, saying the victims were blindfolded, bound to chairs with cable ties and touched with a stun gun, and said the cannabis carried a high risk of spreading the harm of illegal drugs through society.[1]
