What is this?
This website is a repository of western names and their translations to Japanese. You can look up how your name is written in katakana and hiragana, and the romaji of that translation.
Because some names are pronounced in multiple ways in English, you might find that your name has more than one translation. Each translation to Japanese is actually just trying to find out the best way to pronounce a word using the rather limited Japanese language.
You can read more about this subject in How to Translate Your Name to Japanese.
The translations in this website aren't dynamic. They were all found in Japanese texts, written in actual Japanese alongside the original western name.
