In January 1999, Shiori Ino, a 21-year-old university student, began dating , a 26-year-old who operated a series of
brothels with his brother Takeshi, a firefighter; Kazuhito lied to Ino that the brothels were "
massage parlors". The two had met at an
amusement arcade near
Ōmiya Station in
Ōmiya Ward,
Saitama. Komatsu claimed to be a 23-year-old entrepreneur who dealt in cars, real estate, and precious metals. After four or five dates, Komatsu began presenting Ino with expensive gifts such as
Louis Vuitton handbags and
Gucci suits in public places and screamed abuse at her when she refused them. Komatsu also began calling Ino at home, despite the fact that she had only given him her cell phone number. Around this time, Ino found a credit card featuring Komatsu's real name inside his car. When Ino attempted to break off contact, Komatsu threatened her until she agreed to keep seeing him. On 24 March, Ino confided in a friend that she feared for her life. On 30 March, Ino wrote a will and attempted again to break off the relationship with Komatsu, but relented after he threatened her family, including insinuations about physically harming her younger brother, an elementary school student. On 14 June, Ino met Komatsu at a cafe and unequivocally stated her intention not to see him again. The same day, Komatsu, Takeshi and their friend went to the Ino family home, and threatened both Ino and her mother, presenting them with a series of lies about Ino being liable for fictional
embezzlements that Komatsu had committed. They threatened Ino's father when he returned from work, who, unmoved, ordered them out of the house after telling them to take the gifts Komatsu had forced on Ino. The three retreated, stating they did not want the gifts back. Unbeknownst to them, Ino had made an audio recording of the entire ordeal, which she presented to the
Saitama Prefecture police station in
Ageo the next day. Despite the outrage of one younger officer, the officers who met Ino told her that she had no case. That day, the Ino family received a call from someone calling himself "Tanaka" demanding the return of the gifts, following a series of about twenty silent calls. This daily barrage of silent calls continued until 26 October. On 16 June, Ino again went to the Saitama police with her parents. The police again refused to take action, and suggested that she was at fault for breaking up with a smitten suitor after accepting expensive gifts. They also went to a free legal clinic run by the Chamber of Commerce, as the police suggested. After a fifteen-minute consultation, the lawyer dismissed their concerns, stating, "But she had a lot of things bought for her, right?" The following day, Ino received a call from Komatsu demanding they get back together. She refused, and stated that she had been to the police. He reacted angrily before hanging up abruptly. On 21 June, Ino sent everything Komatsu had forced on her to his address by courier service. The following day, 22 June, He approached 33-year-old Yoshifumi Kubota, a former manager of one of their massage parlors, with a
¥20 million
murder-for-hire scheme at Komatsu's behest. Kubota agreed, and in turn recruited two acquaintances, Akira Kawakami and Yoshitaka Ito. On 5 July, Komatsu departed Saitama Prefecture for
Naha,
Okinawa Prefecture, to build an alibi for the planned assassination of Ino. Over the next four months, Ino's family endured an escalating series of harassments and threats, including hundreds of posters and letters slandering Ino and her father distributed throughout the neighborhood and to the father's workplace. The family repeatedly went to the police armed with the letters, photos of license plates and other evidence, without any action being taken. They pressed
libel charges, only to be actively obstructed by senior precinct police officers who were worried that having unresolved open cases would hurt their standing. In the meantime, Kubota, Kawakami and Ito, possessing a photograph of Ino, watched her residence and the local train station to plan her murder. == Murder ==
