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.

Good but needs frequencies

This gives a lot of readings for names, but it doesn’t do a good job of telling you which names/readings are common and which ones are rare.

A great icebreaker

This app really fills a gap! I have English-Japanese dictionary apps and Japanese-Japanese dictionary apps, but they don't contain names. This app quickly finds peoples' names and has been a great conversational ice-breaker for me dozens of times, since when someone tells me their name I can type in the reading and then show them the phone so they can pick out the kanji combination for their name. Over and over again, Japanese people are amazed by this app. I love it.
