Mailing Used Contraceptives to Workplace… Former Post Office Employee Drives Victim to PTSD: “Unprecedented Sex Crime”

Damage occurred in approximately 20 locations nationwide

On April 10 of this year, Yasuhiro Nakajima, 43, a former postal worker, was arrested by the Osaka Prefectural Police (later indicted at home) on suspicion of obstructing business by force for sending an envelope containing used contraceptives to a female employee at a post office in Osaka Prefecture. A subsequent police investigation revealed Nakajima’s horrific additional crimes. He used his position as a postal worker to send similar envelopes to female postal workers throughout Japan.

In mid-December last year, brown envelopes addressed to female post office workers arrived at more than a dozen post offices in the prefecture. When we opened it, we found contraceptives and tissues with bodily fluids inside. The envelope seemed to contain a message saying “I love you” and “Please contact me” and a note with the sender’s e-mail address.

The addresses were written in ballpoint pen, and the handwriting was identical. Most of the postmarks were from Kyoto, where Nakajima’s home is located. In order to avoid having his employment at the Neyagawa Post Office exposed, Nakajima mailed the letters from a mailbox he passed on his way to work,” said a reporter from the society department of a national newspaper.

Nakajima also took advantage of his position as a postal worker to select his targets.

Nakajima was searching for women of his choice in the official newspaper of the labor union of the Japan Post Group. The newspaper contains the names and portraits of the members and the post offices where they work. After his arrest, investigations revealed that similar cases had occurred at about 20 post offices in nine prefectures in Japan, mainly in the Kansai region, but also in Hokkaido, Gifu, Nara, Kumamoto, and other prefectures.

DNA analysis of bodily fluids on the envelopes and handwriting revealed Nakajima’s involvement. Two envelopes containing used contraceptives were seized from Nakajima’s home.

He ransacked women near his home.

Nakajima is believed to have been a habitual offender. A source close to the investigation revealed, “It was not only Japan Post employees who were targeted.

A female employee of the city hall near her home and a female employee of a general company were also victims. When the defendant Nakajima happened to find a woman of her type at the counter of a government office or company she was visiting on business, she would check the nameplate with her full name on it and send her a used contraceptive.

Defendant Nakajima was an assistant section chief at the Neyagawa Post Office, but was dismissed on disciplinary grounds following the incident. In his personal life, it seems that he was kicked out of his house by his wife, who had grown attached to him. Some of the victimized women have developed PTSD (post-traumatic stress disorder).

In response to police investigations, Nakajima denied some of the charges , saying that he sent them to satisfy his sexual desires but did not intend to interfere with business, but in July he was indicted at home by the Sakai branch of the Osaka District Public Prosecutors Office for obstruction of business.

Nakajima injured numerous women to satisfy his sexual desires. Now that he has lost his job as an assistant section chief and has been forced to flee his home by his family, we wonder if he has come to terms with his crimes.
