Japanese Grammar: A Practical Beginner’s Guide

---

Japanese grammar becomes much less abstract when you keep one useful sentence in view and change one part at a time.

This guide starts with a simple sentence, shows what each part is doing, and then builds the verb forms, particles and patterns you can reuse in your own conversations.

Getting Started with Japanese Grammar

Here is the anchor sentence for this guide:

私は毎朝コーヒーを飲みます。 (Watashi wa maiasa kōhī o nomimasu.): “I drink coffee every morning.”

• 私は (watashi wa) sets “me” as the topic.
• 毎朝 (maiasa) gives the time: “every morning”.
• コーヒーを (kōhī o) marks coffee as the object.
• 飲みます (nomimasu) is the polite non-past form of “drink”.

Those four chunks already give you a sentence pattern you can adapt. The rest of the guide explains the choices inside it.

Basic Japanese Sentence Structure: The Predicate Usually Comes Last

Japanese is often introduced as subject–object–verb, but that is only a starting point. A more useful rule is that the predicate tends to come at the end of a clause. The predicate may be a verb, an adjective or a noun expression.

In 私は毎朝コーヒーを飲みます, the verb 飲みます comes last. The time phrase can move when the context or emphasis changes: 毎朝、私はコーヒーを飲みます is also possible. That does not mean every word can go anywhere. Particles, familiar word-order patterns and context all help a listener recover each role.

Japanese also leaves out information that is already clear. Once the conversation is about you, 毎朝コーヒーを飲みます (“I drink coffee every morning”) is often enough. Treat omission as a context choice, not a command to delete every subject or topic.

Japanese Verb Tenses and Verb Classes

Japanese verbs contrast non-past and past forms. The non-past form can describe a present habit or a future event, with time words and context doing much of the work:

• 毎朝コーヒーを飲みます。: “I drink coffee every morning.”
• 明日コーヒーを飲みます。: “I’ll drink coffee tomorrow.”
• 昨日コーヒーを飲みました。: “I drank coffee yesterday.”

Verbs do not agree with grammatical person or number. 飲みます can describe the speaker, the listener or somebody else once the sentence supplies that context. The verb still changes for time, affirmation or negation, and style.

Beginner materials usually divide verbs into three groups:

• Ichidan verbs, often called る-verbs, such as 食べる (taberu, “eat”) and 見る (miru, “see”).
• Godan verbs, often called う-verbs, such as 飲む (nomu, “drink”), 書く (kaku, “write”) and 帰る (kaeru, “return”).
• Core irregular verbs: する (suru, “do”) and 来る (kuru, “come”). Compounds and some specialised verbs also have forms you need to learn in context.

The labels describe conjugation groups, not just the final kana. Some verbs ending in る, including 帰る, are godan verbs. Learn a new verb with its group and one diagnostic form instead of guessing from る alone.

Understanding Japanese Polite and Plain Styles

飲みます belongs to the です/ます style, often called polite style. It is useful in many first meetings, service encounters and conversations where some distance is appropriate. It is not a universal guarantee that every sentence will suit every relationship.

飲む is the dictionary form and the plain non-past affirmative form. “Plain” does not mean “unconjugated”: 飲まない is plain non-past negative, and 飲んだ is plain past. Plain style is common with friends and family, in private thought, and in many kinds of writing, but the setting and relationship still matter.

Learn the form and the sentence style as separate choices. 行きます and 行く both mean “go” in the non-past, but they place the sentence in different styles.

Japanese Grammatical Gender and Counters

Japanese nouns do not belong to masculine and feminine grammatical classes. You do not need to memorise a noun’s gender before choosing an article or adjective ending.

Speech choices can still suggest age, region, group identity, stance or persona. Avoid learning a shortened form as simply “for men” or another expression as “for women”; real usage depends on the speaker and situation.

Counting is a different issue. Japanese commonly combines numbers with counters chosen for the type or shape of what you are counting:

• 本が一冊あります。 (Hon ga issatsu arimasu.): “There is one book.”
• コーヒーを二杯飲みます。 (Kōhī o nihai nomimasu.): “I drink two cups of coffee.”

Our guide to Japanese numbers and counters takes that system further.

Japanese Verb Conjugation

Verb group matters when you build the ます-form.

• For a confirmed ichidan verb, remove the final る and add ます: 食べる → 食べます; 見る → 見ます.
• For a godan verb, change the final u-row kana to the matching i-row kana, then add ます: 飲む → 飲みます; 書く → 書きます; 帰る → 帰ります.
• Learn the core irregular forms directly: する → します; 来る → 来ます.

The part before ます is commonly called the ます-stem: 飲み in 飲みます, or 食べ in 食べます. Several useful patterns attach there, but not every Japanese ending does. Check the pattern instead of assuming every ending attaches to this stem.

If you are still getting comfortable with kana, keep our Japanese alphabet charts beside you. For the wider form system, use the Japanese verb conjugation guide.

Forming Questions in Japanese

A polite question often ends in か:

• コーヒーを飲みますか。: “Do you drink coffee?” or “Will you drink coffee?”
• お名前は何ですか。: “What is your name?”

In familiar conversation, context and rising intonation can mark a question: コーヒー飲む？ (“Want coffee?” or “Will you drink coffee?”). The missing particle and exact English meaning depend on the situation, so do not turn that one example into a rule for every casual question.

か is a grammatical marker, not a literal replacement for punctuation. Formal prose may close a question ending in か with 。, while messages and other informal writing often use ？. Follow the style of the medium you are writing in.

Japanese Particles

Particles show grammatical and discourse roles. Three of the first ones beginners meet are は, が and を:

• は, pronounced wa as a particle, marks a topic or contrast: 私は毎朝コーヒーを飲みます sets 私 as the topic.
• が marks a grammatical subject or focus in many constructions: コーヒーがたくさんあります means “There is plenty of coffee.”
• を, usually pronounced o, marks a direct object here: コーヒーを飲みます means “I drink coffee.”

は and が are not two interchangeable labels for “subject”. Which one fits depends on what the sentence presents as its topic, subject, focus or contrast. Our Japanese particles guide gives those choices more room.

Possessive Form in Japanese

の connects one noun to another. Possession is one common relationship:

友達の本 (tomodachi no hon): “a friend’s book”

But の is broader than an English apostrophe-s. 日本語の文法 (nihongo no bunpō) means “Japanese grammar”: 日本語 specifies what kind of grammar. In this pattern, the modifier comes before の and the main noun comes after it.

“Because” in Japanese

から can connect a reason to what follows:

お腹が空いたから、ご飯を食べます。 (Onaka ga suita kara, gohan o tabemasu.): “I’m hungry, so I’ll eat.”

The reason comes before から, and the result follows it. Here, the reason clause uses the plain form 空いた, while the final 食べます sets the overall sentence in polite style.

“There Is” and “There Isn’t” in Japanese

Japanese normally uses いる for the existence of people and animals, and ある for things and plants. That is a grammatical convention rather than a biology lesson.

• 犬がいます。: “There is a dog.”
• 犬がいません。: “There isn’t a dog.”
• 本があります。: “There is a book.”
• 本がありません。: “There isn’t a book.”

The noun that exists is commonly marked with が. The polite negative forms are いません and ありません.

“Let’s”, “Shall We?” and “Would You Like To…?” in Japanese

These three invitations are related, but they do different jobs:

• 一緒に食べましょう。: “Let’s eat together.”
• 一緒に食べましょうか。: “Shall we eat together?”
• 一緒に食べませんか。: “Would you like to eat together?”

ませんか is a common polite invitation. It is not automatically a higher rung than ましょうか in every situation. Choose between a suggestion, a joint decision and an invitation based on what you are doing.

“Want” in Japanese

To express wanting to do an action, add たい to the ます-stem:

• 食べます → 食べたいです。: “I want to eat.”
• 飲みます → 飲みたいです。: “I want to drink.”

A statement with たい normally presents the speaker’s own desire. Questions can ask what the listener wants, while statements about somebody else’s inner desire need more context and often a different construction.

For wanting a thing, が欲しい is a useful beginner pattern: 新しい本が欲しいです (atarashii hon ga hoshii desu) means “I want a new book.”

Using や for “Things Like A and B”

や links representative examples in a noun list rather than claiming the list is complete:

週末は、読書や料理をします。 (Shūmatsu wa, dokusho ya ryōri o shimasu.): “At weekends, I do things such as reading and cooking.”

The sentence leaves room for other weekend activities. When you mean a complete pairing such as “coffee and tea”, と is usually the first particle to learn: コーヒーとお茶.

“Plan To Do” in Japanese

Use a plain non-past verb before つもりです to state an intention:

来年、日本に行くつもりです。 (Rainen, Nihon ni iku tsumori desu.): “I intend to go to Japan next year.”

行く is plain, but the final です makes the whole sentence polite. つもり expresses an intention; it does not promise that circumstances cannot change.

“Maybe,” “Probably” and “Only” in Japanese

多分 (tabun) can mean “probably” or “perhaps”. It often appears early in a sentence, but its position and strength depend on context:

多分、明日は雨でしょう。 (Tabun, ashita wa ame deshō.): “It will probably rain tomorrow.”

In that sentence, でしょう marks a prediction or conjecture. In other contexts and with different intonation, it can also seek confirmation. Neither 多分 nor でしょう encodes a fixed percentage of certainty.

だけ follows the part it limits:

今日は一時間だけ勉強します。 (Kyō wa ichijikan dake benkyō shimasu.): “I’ll study for only one hour today.”

Practise Japanese Grammar as Sentence Changes

You do not need to memorise this guide as a loose inventory. Take the anchor sentence and practise a small set of contrasts:

1. Read 私は毎朝コーヒーを飲みます aloud, then cover it and retrieve it.
2. Change one slot: replace 毎朝 with 昨日, or コーヒー with お茶.
3. Change the verb contrast: 昨日コーヒーを飲みました; 今日はコーヒーを飲みません.
4. Turn it into a question: コーヒーを飲みますか.
5. Use one version in a message or conversation, get one correction, and retrieve the corrected sentence again the next day.

This example → category → rule → practice sequence helps you connect a form to a communicative job. Listening and reading then give you more examples of the same choices in context.

If the JLPT N5 is one of your goals, these patterns are useful foundations, but the test does not publish one fixed official grammar checklist. Combine grammar practice with reading, listening and our JLPT N5 kanji guide.
