A study conducted by Tohoku University (northern Japan) predicts that by 2500 All Japanese people will have the last name Sato.currently the most common surname in the Asian country due to demographic decline trends and current civil laws.

“Sato” occupies first place among the most common surnames among the Japanese, and last year 2023 he wore it 1.5 percent of Japan’s population According to estimates from a study conducted by Professor Hiroshi Yoshida from the Center for Social and Economic Research on Aging at the aforementioned university.

This academician estimates that the number of people with the surname Sato was multiplied by 1.0083 in recent years and has conducted research into how this figure will change given demographic trends of accelerated aging and decrease in the number of birthsresulting in a continuing net loss of population.

Their study also takes into account Japanese rules, which stipulate that when entering into a marriage husband and wife must take the same surname, either his or hers. In Japan, only the surname and first name are used.

Based on these factors, Yoshida estimated that in 2446, half of the Japanese population would bear the surname “Sato”. 2531 all Japanese will have the same surname.

The study was released amid ongoing debate in Japan over the aforementioned civil surname rules. Numerous voices, including representatives of the ruling party, demand that husband and wife can keep their last names after marriage or even having two surnames, as happens in countries such as Spain.

The report’s authors sought to “illustrate with figures the problem of selective separation of surnames in marriages,” Yoshida said at the presentation of his report.

“If everyone had the surname “Sato san” (“Don or Mrs. Sato”), there would be no choice but to use only name to identify yourself. This would not be an ideal scenario,” the professor said in a statement published by local media.
