Satō (Japanese: さとう; 佐藤, pronounced [saꜜtoː], English: /ˈsɑːt/ SAH-toh) is the most common Japanese surname with 2 million people having the surname, representing about 1.5% of Japan's population in March 2023.[1][2] It is often romanized as Sato, Satou or Satoh.

A 2024 study by Hiroshi Yoshida at Tohoku University estimated that if a law requiring spouses to have the same surname is not repealed and the Japanese people do not go extinct due to population decline, then every person in Japan will have the surname Satō by c. 2531 — legalizing separate surnames for married couples would delay this to c. 3310.[3][1]

Origin

The origin of the name Satō dates back to Fujiwara clan. It is believed that the surname originated in Sano, Tochigi where Fujiwara no Hidesato (藤原秀郷), a military commander from the Heian period, and was the governor of Sano Province, whose descendants combined the kanji character for "Sa" () from Sano (佐野) and the "tō" () from Fujiwara (藤原), which means "Fujiwara of Sano".[4][2]

Satō Day

Satō Day (佐藤の日, Satō no Hi) is an annual event held in Sano, Tochigi, every March 10. Where the city offers discounts and calls itself the "Holy land of Satō". The city also created the Satō Association (佐藤の会). And in 2025, in partnership with Kainan, Wakayama, the birthplace of the name Suzuki (the second most common surname in Japan[4]), a baseball match was held between people with the surname Suzuki and Satō in Ajec Sano Baseball Stadium.[5]
