Japanese volitional invitation form

“Let’s eat first!” “I intend to study seriously this year.” These two sentences look simple, but Japanese uses several different patterns for invitations, intentions, and personal decisions.

The invitation form is called 意向形いこうけい (ikou-kei / volitional). You also need to separate patterns that often get mixed up: ~たい, ~つもり, ~ようと思う, ~ようにする, and ~ようになる.

This article will help you:

  1. Form the volitional for every verb group.
  2. Choose the most natural pattern for the context.
  3. Avoid mistakes that are extremely common among learners.

1. When to Use the Volitional Form

In practice, there are four main functions:

FunctionPatternNuance
Invite (casual)~ようRelaxed, close friends
Invite (polite)~ましょうNeutral-polite; common in class/work
State intention~ようと思う / ~つもりだPersonal plan
Build habit / show change~ようにする / ~ようになるConscious effort vs resulting change

Short version: for “let’s,” use the volitional. For “I want,” that is usually not volitional but ~たい.


2. Full Volitional Formation

2a. Casual form: ~よう / ~おう

Ichidan (る-verb)

Drop る and add よう.

DictionaryVolitional
食たべる食たべよう
見みる見みよう
起おきる起おきよう

Godan (u-verb)

Change the final syllable to the お row and add う.

DictionaryChangeVolitional
行いくく → こ行いこう
読よむむ → も読よもう
話はなすす → そ話はなそう
待まつつ → と待まとう
帰かえるる → ろ帰かえろう

Irregular

DictionaryVolitional
するしよう
来くるこよう

2b. Polite form: ~ましょう

Quick formula: ます-stem + ましょう

Dictionaryますましょう
食たべる食たべます食たべましょう
行いく行いきます行いきましょう
するしますしましょう
来くるきますきましょう

2c. Extra note: the “I will not” form (~まい)

Pattern ~まい marks a negative intention such as “I will not…,” with a somewhat formal or literary feel.

Example:

二度にどと遅刻ちこくするまい。
(Nido to chikoku suru mai.)
I am determined not to be late again.

For beginners, recognize this pattern first; you do not need to use it actively yet.


3. Main Uses + Contextual Examples

3a. Direct invitation: ~よう / ~ましょう

Example 1
一緒いっしょに昼ひるご飯はんを食たべよう。
(Issho ni hirugohan o tabeyou.)
Let’s have lunch together.

Example 2
そろそろ帰かえりましょう。
(Sorosoro kaerimashou.)
Let’s head home soon.

Example 3
この問題もんだいをもう一回いっかい確認かくにんしましょう。
(Kono mondai o mou ikkai kakunin shimashou.)
Let’s check this problem one more time.

3b. Softer invitation: ~ませんか

~ましょう sounds like “let’s do it.” ~ませんか is softer, like “would you like to…?”

Example 4
週末しゅうまつ、映画えいがを見みませんか。
(Shuumatsu, eiga o mimasen ka.)
This weekend, would you like to watch a movie?

Example 5
時間じかんがあれば、あとで話はなしませんか。
(Jikan ga areba, ato de hanashimasen ka.)
If you have time, would you like to talk later?

3c. Personal intention: ~ようと思う vs ~つもりだ

~ようと思う is often used for decisions that just came up or are still forming.
~つもりだ is firmer: the intention is already clear.

Example 6
今年ことしは毎日まいにち日本語にほんごを勉強べんきょうしようと思おもいます。
(Kotoshi wa mainichi Nihongo o benkyou shiyou to omoimasu.)
This year I intend to study Japanese every day.

Example 7
来月らいげつから日本にほんで働はたらくつもりです。
(Raigetsu kara Nihon de hataraku tsumori desu.)
Starting next month I plan to work in Japan.

3d. Conscious effort: ~ようにする

Used when you deliberately build a habit.

Example 8
夜よるは甘あまいものを食たべないようにしています。
(Yoru wa amai mono o tabenai you ni shite imasu.)
I try not to eat sweet things at night.

Example 9
分わからない単語たんごはすぐ辞書じしょで調しらべるようにしています。
(Wakaranai tango wa sugu jisho de shiraberu you ni shite imasu.)
I make a habit of checking the dictionary right away when I don’t know a word.

3e. Resulting change: ~ようになる

Used when a condition changes, often from “cannot” to “can.”

Example 10
半年はんとし勉強べんきょうして、ひらがながすらすら読よめるようになりました。
(Hantoshi benkyou shite, hiragana ga surasura yomeru you ni narimashita.)
After studying for half a year, I became able to read hiragana smoothly.

Example 11
このアプリを使つかってから、復習ふくしゅうする習慣しゅうかんができるようになった。
(Kono apuri o tsukatte kara, fukushuu suru shuukan ga dekiru you ni natta.)
Since I started using this app, I developed a habit of reviewing material.

3f. The “about to” pattern: ~ようとする

~ようとする means trying to start an action or almost doing an action.

Example 12
家いえを出でようとしたとき、電話でんわが鳴なった。
(Ie o deyou to shita toki, denwa ga natta.)
Just as I was about to leave the house, the phone rang.


4. Comparisons That Often Confuse Learners

PatternFocusShort exampleWhen to use
~ようInvitation行いこうCasual invite with friends
~ましょうPolite invitation行いきましょうClass, meetings, service
~たいOwn desire行いきたい“I want to go”
~ようと思うIntention (still forming)勉強べんきょうしようと思うFresh or gradual decision
~つもりだStrong intention留学りゅうがくするつもりFirmer plan
~ませんかSoft invitation行いきませんかInvite without pressure

Quick contrast

A) 映画えいがを見みよう。
(Eiga o miyou.)
Let’s watch a movie.

B) 映画えいがを見みたい。
(Eiga o mitai.)
I want to watch a movie.

Sentence A = invitation. Sentence B = personal desire.

明日あした勉強べんきょうするよう明日あした勉強べんきょうしようと思うBare ~よう is not a full intention marker

日本にほんに行いこうです日本にほんに行いくつもりですVolitional does not combine directly with です as a formal intention pattern

8. Case Studies in Choosing Patterns

This section helps you pick patterns quickly in real situations. Read the context, choose the most natural pattern, and check the reason.

Case 1: Inviting a close friend

Context: You and a friend are close and chatting casually.

Most natural sentence:

今日きょう、新あたらしいカフェに行いこう。
(Kyou, atarashii kafe ni ikou.)
Today, let’s go to the new café.

Why: ~よう sounds light and friendly with close relationships.

Case 2: Inviting a more senior coworker

Context: You want to invite a senior to lunch without sounding pushy.

Safe sentence:

よろしければ、昼ひるごはんをご一緒いっしょしませんか。
(Yoroshikereba, hirugohan o goissho shimasen ka.)
If it’s all right, would you like to have lunch together?

Why: ~ませんか is softer than ~ましょう, especially when inviting someone of higher status.

Case 3: Intention still taking shape

Context: You are not 100% fixed yet, but you already have a direction.

今年ことしは毎日まいにち日記にっきを書かこうと思おもっています。
(Kotoshi wa mainichi nikki o kakou to omotte imasu.)
This year I intend to write a journal every day.

Why: ~ようと思っている fits an active intention still being built.

Case 4: Firm intention with commitment

Context: You have already made a concrete decision.

来年らいねん、日本にほんで働はたらくつもりです。
(Rainen, Nihon de hataraku tsumori desu.)
Next year I plan to work in Japan.

Why: つもり is stronger than ようと思う.

Case 5: New habit vs resulting change

Context A (effort): You are building a routine.

毎晩まいばん、三十分さんじゅっぷん復習ふくしゅうするようにしています。
(Maiban, sanjuppun fukushuu suru you ni shite imasu.)
Every night I make a habit of reviewing for 30 minutes.

Context B (result): the habit is starting to pay off.

いまは授業じゅぎょうの内容ないようがすぐ分わかるようになりました。
(Ima wa jugyou no naiyou ga sugu wakaru you ni narimashita.)
Now I can understand class content quickly.

Why: ようにする focuses on process; ようになる focuses on result.


9. Sentence Production Checklist (Ready to Use)

When speaking, use this checklist to pick the right pattern.

  1. Am I inviting someone?
    Use ~よう (casual) or ~ましょう (polite).

  2. Do I want a soft invitation?
    Use ~ませんか.

  3. Do I want to say “I want”?
    Use ~たい, not the volitional.

  4. Do I want to state a personal intention or plan?
    Choose ~ようと思う (still forming) or ~つもり (firmer).

  5. Do I want to talk about a new habit?
    Use ~ようにする.

  6. Do I want to talk about skill progress as a result?
    Use ~ようになる.

Ready-made patterns for daily practice

  • 明日あしたは早はやく寝ねよう。
    (Ashita wa hayaku neyou.)
    Tomorrow let’s go to bed earlier.

  • よかったら、あとで電話でんわしませんか。
    (Yokattara, ato de denwa shimasen ka.)
    If you’d like, shall we call later?

  • 来月らいげつから会話かいわクラスを始はじめるつもりです。
    (Raigetsu kara kaiwa kurasu o hajimeru tsumori desu.)
    Starting next month I plan to join a conversation class.

  • 毎日まいにち、新あたらしい単語たんごを五個ごこ覚おぼえるようにしています。
    (Mainichi, atarashii tango o goko oboeru you ni shite imasu.)
    I make a habit of memorizing five new words every day.

If you can write at least five sentences from the patterns above each day for a week, control of the volitional will grow much faster.


10. Independent Production Practice (7 Days)

Invitation form should not stop at “I understand.” Train active production with this plan for a week:

Day 1-2: Invitations

Write 6 invitations: 3 casual (~よう) and 3 polite (~ましょう).

Examples:

  • 週末しゅうまつは図書館としょかんで勉強べんきょうしよう。
  • 会議かいぎの前まえにアジェンダを確認かくにんしましょう。

Day 3-4: Intention and plans

Write 6 sentences about your study goals:

  1. two sentences with ~ようと思う
  2. two sentences with ~つもり
  3. two sentences with ~予定

Example:

来月らいげつから毎朝まいあさシャドーイングしようと思おもっている。
(Raigetsu kara maiasa shadooingu shiyou to omotte iru.)
Starting next month I intend to do shadowing every morning.

Day 5-6: Habits and change

Write 4 sentences with ~ようにする and 4 with ~ようになる.

This makes the difference between “effort” and “result” sentences clear.

Day 7: Reflection

Write one short paragraph with:

  1. one invitation
  2. one intention
  3. one new habit
  4. one ability change

If your paragraph hits all four points without opening notes, your volitional foundation is stable enough for real conversation.


11. 60-Second Lightning Recap

Before closing the lesson, test yourself with four questions:

  1. Inviting a friend casually -> which pattern?
  2. Softly inviting a superior -> which pattern?
  3. Stating a firm mid-term intention -> which pattern?
  4. Explaining a new habit vs skill progress -> which patterns differ?

If your answers are よう, ませんか, つもり, and ようにする/ようになる, your foundation is on track.

End goal: in spontaneous conversation, you can move from invitation to intention without sounding stiff.

Conclusion

  • ~よう / ~ましょう are used for invitations.
  • ~たい is used for personal desire, not invitation.
  • ~ようと思う and ~つもりだ both mark intention, but with different firmness.
  • ~ようにする = effort to build a habit; ~ようになる = resulting change.
  • ~ませんか is a softer, safer invitation option in many social situations.
