Imperative Form in Japanese

In Brief

The Japanese imperative (命令形, めいれいけい) gives a direct, forceful command: 行け “Go!” or 食べろ “Eat!” Godan verbs change their final u-row kana to the matching e-row kana; ichidan verbs replace る with ろ (or the more literary よ). A strong negative command uses the dictionary form plus な: 触るな “Don’t touch.”

Overview

The imperative is a verb form used to tell someone to act. In English, a bare verb such as “Go!” can sound neutral, urgent, encouraging, or rude depending on context. The Japanese imperative has a narrower range: it normally sounds forceful, abrupt, and socially marked. You will hear it in emergencies, sports, military-style instructions, angry speech, dramatic dialogue, slogans, and commands from someone with clear authority.

This B1 topic builds on the plain or dictionary form, the basic unpolished verb form found in dictionaries. You need to know whether a verb is godan (a verb whose final kana changes across five vowel rows) or ichidan (a verb that usually drops final る before an ending). That classification determines the affirmative imperative. The negative pattern is simpler because it starts from the dictionary form.

Learning the form does not mean using it in every situation where English uses an imperative. In ordinary Japanese conversation, requests with 〜てください, softer 〜て, or prohibitions with 〜ないでください are usually safer. The direct imperative is nevertheless essential for understanding warnings, fiction, public messages, and emotionally intense speech.

How It Works

Godan verbs: move the final kana to the e-row

For a godan verb, change the last kana from its u-row sound to the corresponding e-row sound. Nothing is added after it.

Dictionary ending	Imperative ending	Dictionary form	Imperative	Meaning
う	え	買う（かう）	買え（かえ）	Buy!
く	け	書く（かく）	書け（かけ）	Write!
ぐ	げ	急ぐ（いそぐ）	急げ（いそげ）	Hurry!
す	せ	話す（はなす）	話せ（はなせ）	Speak!
つ	て	待つ（まつ）	待て（まて）	Wait!
ぬ	ね	死ぬ（しぬ）	死ね（しね）	Die! — extremely hostile outside quoted or fictional contexts
ぶ	べ	遊ぶ（あそぶ）	遊べ（あそべ）	Play!
む	め	読む（よむ）	読め（よめ）	Read!
る	れ	走る（はしる）	走れ（はしれ）	Run!

The useful shortcut “change u to e” refers to the final sound row, not to replacing the written character う in every verb. Thus 待つ becomes 待て, and 読む becomes 読め.

Some verbs ending in る are godan, so they take れ, not ろ. Common examples include 入る → 入れ “Enter!”, 走る → 走れ “Run!”, 帰る → 帰れ “Go home!”, and 切る → 切れ “Cut!” Knowing the dictionary form alone does not always reveal the verb class.

Ichidan verbs: replace る with ろ or よ

For an ichidan verb, remove final る and add ろ. This is the usual direct spoken form. The ending よ is also grammatically valid, but it is associated more with formal written instructions, elevated language, set expressions, and literary or dramatic style.

Dictionary form	Common imperative	Alternative	Meaning
食べる（たべる）	食べろ	食べよ	Eat!
見る（みる）	見ろ	見よ	Look!
起きる（おきる）	起きろ	起きよ	Get up!
信じる（しんじる）	信じろ	信じよ	Believe!

Do not mistake final よ here for the sentence-ending particle よ. In 見よ, the よ is part of the imperative form itself.

Irregular verbs

The two main irregular verbs must be learned separately.

Dictionary form	Direct imperative	More formal/literary alternative	Meaning
する	しろ	せよ	Do it!
来る（くる）	来い（こい）	—	Come!

Notice the reading change in 来い: it is pronounced こい, not くい. In compounds with する, the same pattern applies: 勉強する → 勉強しろ／勉強せよ.

One frequent special case is くれる “to give to me/us.” Although it otherwise behaves as an ichidan verb, its command is くれ, as in ちょっと待ってくれ “Wait a moment, please/do me a favor and wait.” This expression can still sound blunt, but 〜てくれ is not identical in force to shouting a bare imperative.

Negative commands: dictionary form + な

To prohibit an action strongly, use the affirmative dictionary form followed by な.

Dictionary form	Negative command	Meaning
触る	触るな	Don’t touch!
入る	入るな	Don’t enter!
動く	動くな	Don’t move!
忘れる	忘れるな	Don’t forget!
する	するな	Don’t do it!
来る	来るな	Don’t come!

This な is a prohibitive particle. It is not the な used after a na-adjective, and it is not built from the ない negative form. The pattern is 食べるな, not 食べないな.

Direct commands versus everyday requests

Japanese offers several ways to influence another person’s action. They are not interchangeable.

Form	Example	Typical effect
Imperative	座れ。	“Sit down.” Forceful and potentially rude
Negative imperative	座るな。	“Don’t sit.” Strong prohibition
〜なさい	座りなさい。	Firm instruction; common from parents or teachers to children
〜て	座って。	Casual “Sit down / Have a seat,” depending on tone
〜てください	座ってください。	Polite request: “Please sit down”
〜ないで	座らないで。	Casual request not to sit
〜ないでください	座らないでください。	Polite “Please don’t sit down”

English often uses “please” to soften an imperative. Japanese usually changes the grammatical construction instead. Adding ください directly to 座れ does not create a normal polite request; use 座ってください.

Examples in Context

Japanese	English	Note
早く行け！	Go quickly!	Urgent godan imperative
黙れ！	Shut up!	Very blunt; angry or dramatic
待て！	Wait!	Abrupt command; also familiar from dramatic scenes
危ない！逃げろ！	Watch out! Run!	Emergency where directness is justified
こっちを見ろ。	Look this way.	Ichidan 〜ろ form
最後まで読め。	Read to the end.	Strong instruction
今すぐ来い！	Come right now!	Irregular 来る → 来い
自分でしろ。	Do it yourself.	Irregular する → しろ; confrontational
絶対に諦めるな。	Never give up.	Negative command used as encouragement or a slogan
ここに入るな。	Do not enter here.	Strong warning or prohibition
動くな！警察だ！	Don’t move! Police!	Authority and urgency
忘れるな、君は一人じゃない。	Don’t forget: you are not alone.	Dramatic but supportive command
よく見よ。	Observe carefully.	Literary or formal 〜よ imperative
各問いに答えよ。	Answer each question.	Formal written instruction, such as an exam
もっと頑張れ！	Keep going! / Try harder!	Can be encouragement, but relationship and tone matter

Common Mistakes

Using the direct imperative as the default for “please”

• Wrong: 水をくれ！ when politely ordering at a café
• Right: お水をください。
• Why: くれ is blunt. English command wording does not map automatically to a socially neutral Japanese request.

Treating every る-verb as ichidan

• Wrong: 帰ろ！ for “Go home!”
• Right: 帰れ！
• Why: 帰る is godan, so final る changes to れ. 帰ろう means “Let’s go home” or “I’ll go home,” while 帰ろ is its casual shortened form—not the imperative.

Building the prohibition from the ない-form

• Wrong: 触らないな！
• Right: 触るな！
• Why: The strong negative command is dictionary form + な. For a softer request, say 触らないで（ください）.

Confusing 来い and 恋

• Wrong reading: 来い as くい
• Right: 来い（こい）
• Why: 来る changes irregularly. The pronunciation こい also matches the noun 恋 “romantic love,” but context and kanji distinguish them.

Mixing an imperative with polite ます

• Wrong: 行けます！ for “Go!”
• Right: 行け！ for a forceful command, or 行ってください。 for a polite request
• Why: 行けます normally means “can go.” The direct imperative does not take ます.

Assuming an anime line is normal daily speech

• Wrong: using 黙れ with a classmate merely to mean “Please be quiet.”
• Right: 静かにして。 or 静かにしてください。
• Why: Fiction uses direct imperatives frequently to show anger, toughness, rank, or urgency. Real-life use can damage the relationship.

Usage Notes

Register and social relationship

A bare imperative presents the speaker’s will with little room for negotiation. It is most natural when immediate action matters more than politeness: 逃げろ！ during a fire, for example. It can also fit an institutional chain of command, a coach’s shouted instructions, or a parent’s forceful warning, but even there the tone can be severe.

Direct imperatives have traditionally been associated with rough or stereotypically masculine speech, especially in fiction. That does not mean every male speaker uses them or that women never do. Age, role, genre, emotion, and the specific verb matter more than a simple gender rule. Learners should recognize the social effect rather than copy a character’s style wholesale.

Signs, slogans, and encouragement

Warnings often permit stronger language than conversation: 立入るな “Keep out” and 手を触れるな “Do not touch.” In actual public signage, however, polite or impersonal wording such as 立入禁止 “No entry” and 触らないでください “Please do not touch” is also very common.

Commands can sound positive in slogans and cheering because they urge someone toward a desired result: 頑張れ！ “Do your best!/Keep going!” and 諦めるな！ “Don’t give up!” Even encouraging forms can feel pressuring in a sensitive situation, so context still matters.

Intonation and punctuation

An exclamation mark is not grammatically required. 行け。 remains an imperative without one. In speech, volume and intonation can make the same form sound like an urgent warning, a cold order, a theatrical line, or enthusiastic support. Written Japanese uses context, punctuation, and surrounding vocabulary to supply those cues.

Beyond the Basics / Advanced Use

Imperatives inside quotations

An imperative can be quoted with と, often after verbs such as 言う “say,” 命じる “order,” or 叫ぶ “shout.” In that structure, the narrator is reporting the wording rather than commanding the reader.

• 先生は「急げ」と言った。 — The teacher said, “Hurry.”
• 隊長は全員に動くなと命じた。 — The captain ordered everyone not to move.

Quotation helps explain why direct forms appear in otherwise neutral or formal prose. A news report may contain 逃げろと叫んだ “shouted for [them] to run” without adopting a rough tone itself.

Literary 〜よ and formal せよ

The 〜よ imperative of ichidan verbs and せよ from する occur in elevated prose, mottos, legal or administrative instructions, examination prompts, and dramatic language. Examples include 次の問いに答えよ “Answer the following question” and 規則を遵守せよ “Observe the rules.” These forms may look more formal than 答えろ or しろ, but they are still commands, not polite requests to an individual.

Set patterns with 〜がいい and 〜たまえ

You may encounter imperatives inside broader patterns whose tone differs from a bare order. 好きにするがいい can mean “Do as you like,” often with a dramatic or dismissive flavor. 〜たまえ, as in 入りたまえ “Come in,” is an old-fashioned or status-marked command associated with a superior addressing an inferior and is now commoner in stylized fiction than neutral conversation. Recognize these patterns before trying to produce them.

Command-like forms without the imperative

Japanese frequently leaves the verb out or uses a noun phrase for concise public instructions: 止まれ is the direct command “Stop!”, while 一時停止 is the standard noun-based wording “Stop” on road signs. Likewise, 禁煙 means “No smoking” without 吸うな. A complete understanding of commands therefore includes recognizing when Japanese avoids a command verb altogether.

Practice Tips

1. Sort verbs before conjugating them. Make three columns—godan, ichidan, irregular—and convert five familiar verbs from each group. Pay special attention to deceptive る verbs such as 帰る, 入る, and 走る.
2. Practice register pairs. Turn each strong command into an everyday request: 待て → 待ってください, 入るな → 入らないでください. This trains both grammar and socially appropriate choice.
3. Listen for setting and relationship. When you hear an imperative in a drama, game, sports broadcast, or announcement, note who speaks, who receives the command, and why directness is acceptable. Do not study the form without its social context.
