Shinjuku–Kabukicho Love Hotel murders

The first victim, known under the pseudonym of Hostess A, was last seen alive checking into room 401 of the New El Sky hotel with a young man on March 19, 1981.[1] A day later, at about 10 a.m., there was no sign of the victim, who was supposed to have checked out of the hotel by that time. This caused an employee to enter her hotel room, where they found the victim strangled to death. An ID found on her identified her as a local 33-year-old hostess. However, her ID turned out to be fraudulent. She was actually a 45-year-old woman who abandoned her family in 1975 to live in Kabukicho. Authorities speculated that she might have worked as a prostitute prior to her death, and that the murderer may have picked her up from her cabaret job.[2]

The second victim, known as Hostess B, was strangled to death with her pantyhose on the night of April 25, 1981. About an hour before her body was discovered, she was seen checking into room 203 of the Coca Palace hotel with a man. All of her clothes were missing except for her yukata. The murderer left behind a few insignificant items of the victim, such as her earrings, sandals, cigarettes, and a lighter.[3]

The victim was estimated to be about 20-years-old and 157 centimeters (5'1) tall. She was also believed to be Taiwanese. Due to the police being unable to identify her, they released a sketch of the victim to the public. However, this led to no results. The authorities believe that she may have lived in a rural area because she had clean lungs and unhealthy teeth.[4]

On June 14, 1981, the third victim, known under the alias of Shoujo A, was last seen alive checking into a hotel room at the Higashioka hotel with a man. The man later walked out of the hotel alone and passed two employees on his way out of the building. The witnesses said that the man wore a suit. Because of the recent murders, the employees were suspicious of the man, and checked his hotel room. In the room, they found the victim with her hands and feet tied, and pantyhose wrapped around her neck. When she was found, she was still alive, but later died in the hospital.[4]

The victim was later identified as a 17-year-old girl who lived in Kawaguchi city. During her autopsy, coffee was found in her stomach. This led authorities to believe that she met the murderer in a coffee shop.[4]

On June 25, 1981, a 30-year-old hostess in an arcade was invited by a man to a love hotel. After checking in to the hotel at about 11 p.m., the man began to strangle the woman. The woman fought back against her attacker, causing him to steal her wallet and run away.[5]

The suspect was described by witnesses as a young, well-dressed man who is about 160 centimeters (5'2) tall. In the third and fourth incidents, he wore black-rimmed glasses, and had a round-face. Despite being seen by multiple witnesses and the surviving victim, a composite sketch of the murderer was never made.[5]
