Everyone in Japan will have the same cognomen by 2531 , agree to a simulation run at the Tohoku University research essence .
Japan , where same - sex marriage is still illegal , presently call for couples to take between their surnames when they get married . Ninety - six percentchoose to go with the valet de chambre ’s name . grant to Professor Hiroshi Yoshida at Tohoku University ’s Research Center for Aging Economy and Society , if the practice of law is not changed this will head to a situation where every Japanese citizen will have the house name " Sato " in a little over 500 years .
As of 2023 , Sato was themost popularsurname in Japan , shared by 1.529 percent of the population . That seems low considering that the title is that shout out " Sato " in 2531 Tokyo will result in just about every local citizen looking in your direction . However , the cognomen Sato grow by 1.0083 times from 2022 to 2023 .
Continuing this increase rate ( a huge presumption ) , everyone becomes Sato by 2531 .
" From a cosmopolitan probability perspective , there are many cases of people marrying into a grouping with a major surname , " thepaper explains , " and if this summons is repeated over a longsighted period of time , there is a possibility that they will be absorbed into the Sato surname and converge . "
If , however , Japan changes the jurisprudence to allow for separate surnames , by that yr only 7.96 percent of Japan ’s citizens will be named Sato ( feign that 39.3 percentage pick out to continue to select one cognomen , the proportion of people who read they would do so in a 2022 survey ) . Under this scenario , we would still reach the Sato totality by 3310 .
" However , according to ' Japan ’s Future Population Projections ' 2023.4 , the Japanese universe in 2120 is estimated to be 41,229,000 . If this stride continues , the Nipponese universe is estimated to be 281,866 in 2,531 and 22 in 3310 , " the paper adds . " In other parole , even if 100 per centum adoption of the Sato surname is postponed for 800 years , there is a high possibility that the Nipponese people themselves will become extinct before that due to the declining fertility rate . "
Of course , it ’s probably not start to play out like that . The research was put together at the request of the Think Name Project , which aims to blackmail the government into allowing matrimonial couples to have separate names , and was mean to highlight an idiotic scenario if the law is not changed . Which is a pity for anybody who wants to know the cognomen of everybody in Japan , but only wants to find out one name .
