Rie Isogai
Rie Isogai was a 31-year-old office worker living in Nagoya. In August 2007, three men who had become acquainted through an underground online bulletin board used to seek criminal accomplices selected her as a robbery target while she was on her way home.
The men abducted Isogai, robbed her and killed her. Her body was later found in a wooded area in Gifu Prefecture. One of the three men surrendered to police soon afterward, helping investigators identify the others.
Investigation and prosecution
Police arrested Tsukasa Kanda, Yoshitomo Hori and Kenji Kawagishi. The prosecution treated the case as a planned robbery-murder carried out by men who had met online rather than as a crime committed by a pre-existing gang.
The online connection became a major part of the public discussion around the case. This page uses that fact only to explain how the offenders came into contact; it does not provide directions to criminal forums or reproduce operational details from their planning.
Trial court sentences
In March 2009, the Nagoya District Court convicted all three men. Kanda and Hori received death sentences, while Kawagishi received life imprisonment. The differing sentence reflected the trial court's assessment of individual responsibility and Kawagishi's cooperation with police.
Kanda later withdrew his appeal, making his death sentence final. The other defendants continued through the appellate process.
Appeals
In April 2011, the Nagoya High Court left Kawagishi's life sentence in place and reduced Hori's sentence from death to life imprisonment. The prosecution appealed, but the life sentences ultimately became final.
Hori was later sentenced to death in a separate prosecution for an unrelated 1998 double murder. That later case is not treated here as part of Rie Isogai's murder and does not change the life sentence that became final for this specific offense.
Kanda's execution
Tsukasa Kanda remained under the final death sentence imposed for Isogai's murder. On June 25, 2015, Japan's Justice Ministry executed him at the Nagoya Detention House. The Justice Minister's official press-conference record described the conviction as final following full judicial review.
The victim's family
Rie's mother, Fumiko Isogai, later became a public advocate for stronger financial and psychological support for families of murder victims. Reporting years after the case emphasized that the consequences of a homicide extend long beyond the criminal trial itself.
