Verb Conjugation Chart in Japanese for Beginners

Japanese Verb Conjugation Chart for Present, Past, Negative, and Polite Forms

Japanese verbs can look a little intimidating at first. Then you learn the pattern, and suddenly the language stops behaving like a mystery and starts behaving like a system. Annoying for the chaos lovers, helpful for everyone else.

If you are building a foundation, this chart will help you handle the four forms beginners meet all the time: present, past, negative, and polite. For a bigger study path, you can also pair this lesson with the main Japanese learning hub and the useful starter list at 100 Japanese Words and Phrases to Start Learning.

One small secret: Japanese verbs do not change for the subject. So “I eat,” “you eat,” and “they eat” all use the same verb form. Less drama, fewer moving parts, more sanity.

The Four Forms You Need First

Form	What It Means	Example Verb	Rōmaji	English
食べる	Present / Dictionary form	食べる	taberu	to eat
食べた	Past	食べた	tabeta	ate / ate it
食べない	Negative	食べない	tabenai	do not eat / does not eat
食べます	Polite present	食べます	tabemasu	eat / will eat (polite)
食べました	Polite past	食べました	tabemashita	ate (polite)
食べません	Polite negative	食べません	tabemasen	do not eat (polite)

Yes, that is already the heart of the chart. Not glamorous, but it works. Japanese loves patterns once you stop staring at the verb like it owes you money.

How The Basic Pattern Works

Most beginner verbs can be grouped into three common types:

る-verbs — usually end in る, like 食べる (taberu, to eat)
う-verbs — often end in sounds like う, く, す, む, like 書く (kaku, to write)
Irregular verbs — the famous troublemakers, mainly する (suru, to do) and 来る (kuru, to come)

We will keep the rules simple. You do not need to memorize every tiny detail today. You need a working chart first, because confidence is built from usable forms, not from suffering.

Useful Verb Forms With Examples

Kanji	Rōmaji	Meaning	Example Sentence	Rōmaji Sentence	English Translation
食べる	taberu	to eat	私はパンを食べる。	Watashi wa pan o taberu.	I eat bread.
食べた	tabeta	ate	昨日、寿司を食べた。	Kinō, sushi o tabeta.	I ate sushi yesterday.
食べない	tabenai	do not eat	私は肉を食べない。	Watashi wa niku o tabenai.	I do not eat meat.
食べます	tabemasu	eat / will eat (polite)	毎朝、パンを食べます。	Maiasa, pan o tabemasu.	I eat bread every morning.
食べました	tabemashita	ate (polite)	もう昼ごはんを食べました。	Mō hirugohan o tabemashita.	I already ate lunch.
食べません	tabemasen	do not eat (polite)	私は甘いものを食べません。	Watashi wa amai mono o tabemasen.	I do not eat sweets.

Present Form: The Dictionary Form

The present form is the form you look up in a dictionary. It is also called the dictionary form. For beginners, this is the base form you should recognize first.

Pattern	Meaning	Example	Rōmaji	English
食べる	to eat	朝ごはんを食べる。	Asagohan o taberu.	I eat breakfast.
書く	to write	手紙を書く。	Tegami o kaku.	I write a letter.
する	to do	勉強をする。	Benkyō o suru.	I study.
来る	to come	友達が来る。	Tomodachi ga kuru.	A friend comes.

Notice something useful: the present form often covers both “I eat” and “I will eat,” depending on context. Japanese likes context to do some of the heavy lifting. Efficient, if slightly smug.

Past Form: Talking About What Already Happened

The past form is used for completed actions and finished events.

Kanji	Rōmaji	Meaning	Example Sentence	Rōmaji Sentence	English Translation
食べた	tabeta	ate	昼ごはんを食べた。	Hirugohan o tabeta.	I ate lunch.
書いた	kaita	wrote	ノートを書いた。	Nōto o kaita.	I wrote notes.
した	shita	did	宿題をした。	Shukudai o shita.	I did homework.
来た	kita	came	先生が来た。	Sensei ga kita.	The teacher came.

For many beginners, past tense is the first place where the verb starts to feel alive. You are no longer naming an action. You are reporting it like a responsible adult. Or at least like a person trying.

Negative Form: Saying No Without Panic

The negative form is used to say something does not happen, does not exist, or is not true.

Kanji	Rōmaji	Meaning	Example Sentence	Rōmaji Sentence	English Translation
食べない	tabenai	do not eat	私は肉を食べない。	Watashi wa niku o tabenai.	I do not eat meat.
書かない	kakanai	do not write	彼は手紙を書かない。	Kare wa tegami o kakanai.	He does not write letters.
しない	shinai	do not do	今日は勉強しない。	Kyō wa benkyō shinai.	I do not study today.
来ない	konai	do not come	友達は来ない。	Tomodachi wa konai.	The friend does not come.

A handy note: negative forms are also very common in casual conversation. If you hear 行かない (ikanai, do not go), it may sound less harsh than English “no” sometimes does. Context saves the day again.

Polite Form: The Safe, Friendly Choice

The polite form is used in neutral, respectful, and everyday situations. If you are unsure what to use, polite is usually a smart default.

Kanji	Rōmaji	Meaning	Example Sentence	Rōmaji Sentence	English Translation
食べます	tabemasu	eat (polite)	毎日、野菜を食べます。	Mainichi, yasai o tabemasu.	I eat vegetables every day.
食べました	tabemashita	ate (polite)	もう食べました。	Mō tabemashita.	I already ate.
食べません	tabemasen	do not eat (polite)	私は朝にパンを食べません。	Watashi wa asa ni pan o tabemasen.	I do not eat bread in the morning.
行きます	ikimasu	go (polite)	学校に行きます。	Gakkō ni ikimasu.	I go to school.
見ました	mimashita	saw / watched (polite)	映画を見ました。	Eiga o mimashita.	I watched a movie.

Polite form is your default good manners setting. It is not fancy. It is not stiff. It is simply safe, clear, and useful.

For a more detailed breakdown of verb groups and grammar terms, a basic reference like Japanese verb conjugation can be a useful companion. Boring source, yes. Very useful, also yes.

Practice: Swap The Verb Form

Try changing each sentence into the requested form. Then check the sample answer.

1. 私は水を飲む。 → Past
2. 彼は本を読む。 → Negative
3. 先生が来る。 → Polite
4. 友達と話す。 → Past
5. 映画を見る。 → Negative

Sample answers:

1. 私は水を飲んだ。 — Watashi wa mizu o nonda. — I drank water.
2. 彼は本を読まない。 — Kare wa hon o yomanai. — He does not read books.
3. 先生が来ます。 — Sensei ga kimasu. — The teacher comes.
4. 友達と話した。 — Tomodachi to hanashita. — I talked with a friend.
5. 映画を見ない。 — Eiga o minai. — I do not watch movies.

Common Mistakes And Fixes

Mistake: Using the same English tense logic too early. Fix: Focus on the Japanese form, not the English label.
Mistake: Forgetting that ます is polite, not a separate meaning. Fix: Think of it as a style change.
Mistake: Mixing up する and します. Fix: する is plain form; します is polite.
Mistake: Assuming every verb follows the same pattern. Fix: Learn the common groups first, then spot the irregular ones.
Mistake: Forgetting to keep the Rōmaji close to the Japanese. Fix: Read them together every time, so your brain stops treating them like separate planets.

Quick Reference Summary

Form	Pattern	Use	Example
Present	dictionary form	current action, general fact	食べる — taberu
Past	past form	completed action	食べた — tabeta
Negative	negative form	not doing something	食べない — tabenai
Polite	ます-form	friendly, respectful speech	食べます — tabemasu

If you can recognize these four forms, you are already doing real Japanese study, not just collecting vocabulary like a squirrel with a notebook.

Yak Takeaway

Japanese verb conjugation becomes much easier when you stop trying to memorize everything at once. Start with the present, past, negative, and polite forms. Learn them with real verbs, real sentences, and lots of repetition. Once these forms feel familiar, the rest of Japanese grammar starts to look less scary and a lot more logical.
