YesJapan.com – George Trombley is a great guy, who really cares about his students. He got me moving with my studies and I cannot thank him enough (even though I don’t call him hardly at all, sorry George). He even came to visit me when I went out to Vegas. This is hands down the best Japanese reference online. The fees are not much, and I guarantee you will have all the study and new information you can stand. You need help, and there are people to help. I was with George a year and change, with mild study daily. I didn’t know I could do ok with my skills until my Japanese family came to visit, and some could not speak English. We had a great time, thanks George!
Denshi Jisho Dictionary – This dictionary may seem limited, but the hot links to each kanji, with example sentences are awesome. This is one of my favorite references.
