Approximately 135 individuals, whose identities remain confidential, are reportedly being protected in Japan for unspecified reasons. The term "protected individuals" often refers to abuse survivors, crime witnesses, or those who are under potential threats. The circumstances or reasons for these individuals' protection are not shared, to maintain their safety and wellbeing.

In Japan, the concept of anonymity is highly regarded and deeply embedded in numerous societal norms. Identity protection of such sorts can commonly involve diverse groups such as victims of domestic abuse, those under police protection, or even former members of criminal organizations. Privacy and ensuring safety from potential danger is heavily prioritized.

In the US and EU, similar instances of identity protection take place. This generally involves witness protection programs where individuals at risk are provided with new identities and moved to confidential locations. However, the disclosure of such cases often depends on the severity of the situation, unlike Japan where most cases are usually not publicly disclosed.
