Types of conjugation
Japanese has two kind of regular verbs; godan and ichidan:

Group I, consonant stem (godan katsuyō)
The type 1 verb (五段活用) is by far the most common, and it follows a basic conjugation pattern, though it contains a few exceptions (e.g., いらっしゃる).

Ending in う (u): To conjugate the godan verb 会う (あう, au) meaning "to meet" the template must be used as such:

Ending in く (ku): To conjugate the godan verb 描く (かく, kaku) meaning "to draw" the template must be used as such:

Ending in ぐ (gu): To conjugate the godan verb 泳ぐ (およぐ, oyogu) meaning "to swim" the template must be used as such:

Ending in す (su): To conjugate the godan verb 殺す (ころす, korosu) meaning "to kill" the template must be used as such:

Ending in つ (tsu): To conjugate the godan verb 待つ (まつ, matsu) meaning "to wait" the template must be used as such:

Ending in ぬ (nu): To conjugate the godan verb 死ぬ (しぬ, shinu) meaning "to die" the template must be used as such:

Ending in ぶ (bu): To conjugate the godan verb 呼ぶ (よぶ, yobu) meaning "to call" the template must be used as such:

Ending in む (mu): To conjugate the godan verb 読む (よむ, yomu) meaning "to read" the template must be used as such:

Ending in る (ru): To conjugate the godan verb 走る (はしる, hashiru) meaning "to run" the template must be used as such:

Group II, vowel stem (ichidan katsuyō)
The type 2 verb (上一型 + 下一型) is less common. All type 2 verbs end in る in plain (dictionary) form, and thus the category is often referred to as る-verbs, but nota bene that this does not mean that every verb ending in る (ru) is a group II verb. They frequently drop the final る rather than transforming it when conjugating.

To conjugate the ichidan verb 見る (みる, miru) meaning "to see" the template must be used as such:

To conjugate the ichidan verb 食べる (たべる, taberu) meaning "to eat" the template must be used as such:

and so on...

Group III, irregular
The type 3 verb, or irregular verb consists of the two verbs 来る and する, and all the verbs that are constructed by affixing 〜する to a noun.

To conjugate the irregular verb する (suru) meaning "to do" the template must be used as such:

To conjugate the irregular verb 来る (くる, kuru) meaning "to come" the template must be used as such:

There are also irregular forms for many words used in polite language, with a final る becoming い in imperative and polite forms. (e.g. 下さる &rarr; 下さい, 下さいます) In addition, the verb くれる have the irregular imperative くれ, and the verb 行く has the irregular conjunctive form 行って.
