What is a good free and reliable website for translating English to Japanese Kanji, and back?

I am looking to get a tattoo, but I don't know anybody that speaks or reads Japanese. I don't trust most of the translation sites I've found, cause when I translate the phrase back to English, it is something completely different...Any help would be appreciated.|||Babel Fish is a good site. Most of the time there is not a direct translation from one language to another. You may have to have someone that speaks it tell you.|||the best way would be to ask a japanese native to do that, but if is a simple phrase, you could study some and make it yourself, but if you only need to look for kanjis, I highly recommend you www.jisho.org|||Best thing would be to post what you want tattooed on here. I'm sure between myself and the other knowledgeable Japanese scholars on here will be able to help you.
