If current laws requiring married couples to share a surname remain unchanged, the entire population of Japan could have the same surname \u2013 Sato \u2013 by 2531, a study by Tohoku University suggests.
\nSato is currently the most common surname in Japan, held by roughly 1.5% of the population.
\nThe research led by Professor Yoshida predicts this number to rise to 100% within the next 500 years.
\nYoshida stressed his estimate was \u201cmechanically calculated based on an assumed scenario\u201d, according to Japanese newspaper The Mainichi.
\nBut he added: \u201cIf everyone becomes Sato, we may have to be addressed by our first names or by numbers.
\nThe study, commissioned by the Think Name Project and other advocates for surname choice, highlights the potential downsides of Japan\u2019s current legislation.
\nUnlike most countries, Japan mandates married couples to adopt a single surname, typically the husband\u2019s.
\nProfessor Yoshida\u2019s research indicates a steady rise in the prevalence of the Sato surname. Data suggests a 1.0083% increase from 2022 to 2023. If this trend continues, half the population could be named Sato by 2446, with everyone sharing the name by 2531.
\nYoshida said everyone having the same surname \u201cwill not only be inconvenient but also undermine individual dignity,\u201d according to Japanese newspaper Asahi Shimbun.
\n\u201cThis would also lead to the loss of family and regional heritage associated with surnames.\u201d
\nThe study also explores an alternative scenario where couples have the freedom to choose separate surnames. In this case, Professor Yoshida predicts only 8% of the population would hold the Sato surname by 2531.
\nThis model takes into account a 2022 survey by the Japanese Trade Union Confederation, where 39.3% of respondents expressed a preference for sharing a surname even if individual options were available.Surname. surname, Japan, legislation<\/p>\n","protected":false},"excerpt":{"rendered":"
