An emerging crime trend in Japan, dubbed "Tokuryu-type crime," is causing alarm due to its increasing severity. The nature of these criminal acts is unusual and brutal, taking societal issues to a new level. Although it remains unspecified when and where these crimes have occurred, experts have begun investigating the root causes behind such brutalization. The primary question under investigation is what societal or psychological triggers drive individuals to engage in these kinds of criminal acts.

Japan's low crime rate has been a point of pride for the nation, but this emerging crime trend raises concern. The unusual brutal nature of these cases has resulted in societal shock and fear which necessitates the intensification of current law enforcement efforts. Given Japan's emphasis on its peaceful society and strict laws, such criminal behavior does not align with the social and legal values held within the nation.

While brutal crimes also occur in the US or EU, crime trends are typically dealt with differently. Most American or European nations have high crime rates compared to Japan, and such unique crimes would likely be categorized and investigated based on their individual characteristics rather than being grouped into a trend. Also, the social impact might be less shocking because of a higher public desensitization to crime.
