A baseball bat with blood residue has been discovered in Shinjuku, a lively commercial area in Tokyo. The finding came during an investigation into an unidentified body found previously, hence deepening the mystery surrounding the case.

Crime rates in Japan are relatively low, and violent crimes such as this are rare. When such incidences occur, they become a significant point of interest and garner widespread media attention. The public generally views these cases from a social safety perspective, with a strong desire for justice. Japan's approach to crime is methodical with a high emphasis on background checks and investigations to conduct a fair trial.

The nature of coverage for such crimes in the US/EU tends to be more concentrated in local news or crime-dedicated sections due to their higher occurrence, unlike in Japan where it becomes a national point of interest. Legal proceedings in the US/EU also place a high value on thorough investigations, but unlike Japan, they have a more public and aggressive prosecution process.
