Hi. If you don't mind English websites...the below are great for explaining grammar. The last site is an online English-Japanese dictionary. http://www.timwerx.net/language/particles.htm http://www.timwerx.net/language/jpverbs/index.htm http://www.guidetojapanese.org/ http://jisho.org/ As for learning kanji...I'm not sure of the best way. The more I see and use them, the more I remember and know.
