The Cold Case Murder Map

I'm not a huge fan of crime maps. I think in many cases they oversimplify or distort patterns of criminal activity. However, I find Japan's Unsolved Murder Cases project particularly compelling.

According to the map, there are at least 369 homicides in Japan (since 1995) that remain under investigation - because the murderer has yet to be identified. The map was created by The Asahi Shimbun, one of Japan’s oldest and most influential newspapers, in response to the 2010 Criminal Procedure Law. This law abolished the statute of limitations for crimes carrying the most severe punishment, such as murder. In practice, this means there is no longer a "time limit" on investigations for crimes committed after April 28, 1995.

To create the map the newspaper interviewed Japan's police departments about unsolved cases involving murder and robbery-murder that occurred between April 28, 1995 and December 31, 2023. The map itself presents a choropleth view of the number of reported cold cases in each prefectural police jurisdiction. 

Clicking on a highlighted prefecture reveals details of individual unsolved murders. Each case entry includes information such as the victim's age, gender, and the circumstances of the incident. Obviously these details can be explicitly gruesome (which may be why I feel a little uneasy about finding the map so compelling).
