Renowned Japanese celebrity, Takamatsu Nana has openly accepted the path of de facto marriage, inviting an array of criticisms. The eminent personality took to social media to share her stance on marital norms, generating an extensive discussion among fans and critics. While the exact date of declaration is unspecified, the news broke out in mainstream Japanese media recently.

In Japan, there is considerable societal importance on traditional family structures and legal marriages. Takamatsu Nana's decision to embrace a non-legal, de facto marriage is seen as a change from traditional norms. This continues to elicit mixed reactions, especially considering the celebrity's massive following.

In contrast to Japan, non-legal marriages or cohabiting relationships are more socially accepted in the US and EU. Celebrities embracing these types of relationships often do not face the high level of scrutiny seen in Japan, reflecting different cultural attitudes towards marital norms.
