Raven here.
I have been studying Japanese for three years at my High School.
We use a web-based program called Quia for submitting in work, so we often get helpful sites. One of them is
The Handy Japanese Verb Conjugator. It helps you by giving you verbs, definitions, and conjugations. There is also the Free Japanese Word Processor, known as
JWPCe. This lets you type in Hiragana and Katakana, as well as inserting Kanji. It also contains a dictionary.
