Popular Japanese actress Mariye recently made public her decision to leave her family registry - a significant move in the deeply traditional Japanese society. It's a bold step that questions the necessity of the koseki system, existing since the 19th century. It is unclear when exactly she decided to take this unconventional route, and the reasons behind her decision are drawing widespread public and media attention.

In Japan, the family registry, or koseki, is a civil document that records information on births, deaths, marriages, and other important family matters. It's deeply rooted in the culture and often viewed as a symbol of familial loyalty and societal conformity. Mariye’s decision is rare and groundbreaking, and as such, is sparking debates on personal freedoms versus traditional norms.

A similar action in the U.S or EU may not resonate the same, as there is no equivalent to the koseki. However, it could loosely be compared to someone legally changing their name or deciding not to marry, both decisions that can also challenge societal norms, and similarly, provoke public discourse on freedom of personal decision-making.
