Japan Dict

JapanDict.com is my favorite online Japanese dictionary. It has a simple no nonsense design. Definitions can be found for both words and independent kanji. And the best part about the site, is that each kanji is broken down into its radical elements which may be investigated for further clarification. This feature compliments the Heisig method greatly. In fact, I used it to understand kanji before I even discovered the Heisig method, and this prior knowledge weighed greatly in my decision to pursue the Heisig method.

Denshi Jisho is another useful online Japanese dictionary. However, its lack of simplicity is at times troubling. As a beginner with the the language, the simplest definition for a given kanji is often the best. This site often lists as many corresponding uses for any given kanji it can produce. This may be helpful for someone adept with the language, but to me, its overkill.
