The 100 most common Japanese surnames
Kanji, reading, what each kanji means and how many people carry the name.

Kanji, reading, what each kanji means and how many people carry the name.
This list comes from a national surname survey by Meiji Yasuda Life Insurance Company, published on 24 September 2008. The company counted the surnames of about 6.1 million of its policyholders and used the share of each surname to estimate how many of Japan's 127.06 million people carry it. The rank is the one Meiji Yasuda published.
The 10 most common surnames make up 10.39% of the policyholders counted, and the 100 on this page add up to an estimated 42.75 million people, about one in three people in Japan. A sample of policyholders is not the whole population, so the populations shown are estimates.
The romanization is the one in the English Wikipedia list. The kana is the JMnedict surname reading that matches it. Where the list gives two romanizations for one surname, both are shown. The kanji meanings come from KANJIDIC2 and describe each character on its own, so they are not a translation of the surname.
