Master Japanese Verb Forms with Our Comprehensive Japanese Verb Forms Chart

Japanese verb conjugation can be challenging, but with our Japanese verb forms chart, you'll gain a clear understanding of Godan, Ichidan, and Irregular verbs. This guide focuses on practical application, making it easier to learn and use in real-life situations.

Understanding the Three Main Verb Groups: Godan vs. Ichidan

Japanese verbs are primarily categorized into three groups: Godan, Ichidan, and Irregular. Understanding these groups is crucial for mastering verb conjugation.

Godan Verbs (五段動詞)

Godan verbs are the most common and have five different endings in their dictionary form. These endings are -u, -ku, -gu, -su, -tsu, -nu, -bu, -mu, and -ru. For example:

• 書く (kaku) - to write
• 食べる (taberu) - to eat
• 見る (miru) - to see

Ichidan Verbs (一段動詞)

Ichidan verbs have a consistent -ru ending in their dictionary form. Examples include:

• 来る (kuru) - to come
• 走る (hashiru) - to run
• 開く (hiraku) - to open

Key Differences

• Godan verbs change their stem vowels when conjugated, while Ichidan verbs maintain a consistent stem.
• Godan verbs have more complex conjugation patterns compared to Ichidan verbs.

Mastering Irregular Verbs: When Verbs Don't Follow the Rules

Irregular verbs, also known as 変格動詞 (henkatsu dōshi), do not follow the standard conjugation patterns. The most common irregular verbs are する (suru) - to do and 来る (kuru) - to come. These verbs have unique conjugation patterns that you need to memorize.

Identifying Irregular Verbs

To identify irregular verbs, look for verbs that do not end in -u, -ku, -gu, -su, -tsu, -nu, -bu, -mu, or -ru. These verbs often have unique conjugation patterns that you need to learn separately.
