How Do You Say “genealogy” In Japanese?


March 30, 2011 by Valerie Elkins

The short answer is keizu. The longer answer is not so easy. There several reasons why it is difficult for those of Japanese ancestry living outside of Japan to trace their lineage. One of the main reasons is a lack of understanding of the language. I am not going to sugar coat it, learning Japanese is hard, BUT learning how to pronounce it is not.

There are 5 basic vowel sounds in Japanese. They are always pronounced the same unlike in English! Vowel lengths are all uniformly short:

a as in ‘father’
e as in ‘bet’
i as in ‘beet’
u as in ‘boot’
o as in ‘boat’

You do not need to know everything in Japanese but learning some genealogical terms is helpful.
