A decades-long unsolved case involving the discovery of a young girl's body in a box is being reopened in Japan, stirring public interest and emotional responses. The case dates back to 20 years ago but was never solved, and its resurgence carries with it lessons from the past. The authorities are hoping for a breakthrough with the advent of advanced crime-solving technology.

In Japan, unsolved cases, particularly those involving children, attract a lot of public attention. Many people feel a personal connection to the victims and want justice to prevail. Japanese society highly values the sanctity of life and safety of children, and such an event contradicts these norms, causing public outrage.

Similar to the US or EU, unresolved cases, especially involving the welfare of a child, are a significant concern to the public and the law enforcement authorities. In both regions, advancements in technology and forensics are being used to review and hopefully resolve old unsolved crimes.
