This program conjugates Japanese verbs to 17 different forms. Except for the
2 irregular verbs and many irregularities of honorific verb form, there are
no other irregular verbs and are very easy to conjugate.
Some of the more vaguely named forms to the non-Japanese speaker are:

-te, negative -te form  Used in conjunction with other words to create other
                        verb tenses
Volitional              Indicates volition, or wanting to do something. Example: "ikou"
                        "Let's go", in English
Potential               Indicates ability
Causative               Indicates the speaker was forced to do something
Causative-passive       Indicates the speaker was forced to do something and was
                        adversely affected by it
Conditional             Like our "if", but conveys the meaning of it being a
                        hypothetical condition
-tai form               Stronger than volitional. Example: "ikitai"
                        "I want to go" in English
