About Dictionary of Japanese Names
CJKI's Japanese Names Dictionary is a based on the CJK Dictionary Institute's comprehensive collections of millions of Japanese names and their variants -- the largest such repository in existence.
Japanese names have been called the "Eighth Wonder of the World". Indeed, even native speakers often have difficulties in determining the correct pronunciation for a name written in kanji, or guessing the kanji for a name written in Latin characters. In extreme cases, one kanji name can be pronounced 36 ways, whereas one romanized name can be written in more than 100 ways.
Q: Do you know how to read the name 一二三 and 海?
A: Kirara and Marin.
Q: Do you know to write in kanji the surname Hashizume?
A: Here some possibilities: 橋詰, 橋爪, 橋都 and 橋誥.
Q: Do you know how many different ways there are of writing Akiko?
A: At least 168! Here are just a few: 明子, 晶子, 昭子, 彰子, 亜喜子, 亜希子, 安貴子 and many more.
