Support in Japanese: 応援おうえん (ouen), 支ささえる (sasaeru), 支持しじ (shiji), and サポート

English "support" becomes 応援おうえん when you cheer someone on, 支ささえる when you carry them, 支持しじ when you agree with and back an idea, and サポート when you help with something practical.

A dictionary gives you a list for "support" and no way to choose. The choice is easier if you ask how you take part, not just who the object is. The same friend can be the object of all four: you 応援おうえん their audition, 支ささえる them through a hard year, 支持しじ their argument, and give サポート with their paperwork. This article sorts the words, covers 支持しじ and 自信じしん (which can be confused by ear), and shows what people actually say for "I support you".

The basics

Which Japanese word should you use for "support"?

Ask how you are taking part. Wishing someone success is 応援おうえん, carrying their weight is 支ささえる, agreeing with and backing an idea is 支持しじ, and helping with a task is サポート. The words overlap at the edges, and 支援しえん is the formal, organizational neighbor of サポート.

Word Reading How you take part Register Example
応援おうえんする おうえんする cheer on a team, an idol, a friend's goal Everyday, warm 友ともだちを応援おうえんする
支ささえる ささえる carry a person, a family, a weight Everyday to literary 家族かぞくを支ささえる
支持しじする しじする agree with and back a party, policy, opinion Formal, news, meetings 政党せいとうを支持しじする
サポート(する) さぽーと help with a task, a user, a project Business, IT, also personal カスタマーサポート
支援しえんする しえんする give aid, resources, advice Formal, organizations 被災地ひさいち(ひさいち)を支援しえんする
味方みかた みかた be on someone's side Everyday あなたの味方みかただよ

The first five are verbs. 味方みかた is a noun, usually with だ or でいる (味方みかただ, 味方みかたでいる). A verb 味方みかたする also exists: 彼かれの味方みかたをする, "to take his side".

What does 応援おうえん mean, and who do you use it for?

応援おうえんする is "to cheer for" or "to root for", used for sports teams, singers, streamers, and friends trying something hard. 応援おうえん is the usual word when an English speaker says "I support you" and means "I want you to succeed".

日本代表にほんだいひょうを応援おうえんしています。 — I'm cheering for the Japan national team. (polite, fan talk) 友ともだちがスピーチ大会たいかいに出でるので、応援おうえんしに行いった。 — My friend was in a speech contest, so I went to cheer. (casual past, 〜しに行いく = go in order to) 推おしを応援おうえんするのが生いきがいです。 — Cheering on my favorite idol is what I live for. (fan culture, 推おし = the person you back)

応援おうえん is mostly about wanting someone to succeed. It doesn't always mean you do something for them, but it can: 応援おうえんに行いく, "go to cheer", is an action, and in a team it can include helping out.

What does 支ささえる mean?

支ささえる literally means "to hold up", so it works for a roof beam and for a person who gets someone through a hard time. 支ささえる is support that bears weight: emotional, financial, or physical.

この柱はしらが屋根やねを支ささえている。 — This pillar holds up the roof. (physical) 夫おっとが家族かぞくを支ささえている。 — My husband supports the family. (financially, or as the one who holds things together) 友ともだちの支ささえになりたい。 — I want to be a support for my friend. (支ささえになる = become someone's pillar, warm)

The noun 支ささえ is common: 心こころの支ささえ is "emotional support", the thing or person that keeps you going.

What does 支持しじ mean?

支持しじする means to agree with something and back it: a party, a candidate, a policy, an opinion. 支持しじ is the news-and-meeting word, so it fits ideas and organizations, not a friend you want to encourage. It doesn't have to be announced; you can 支持しじ a party in private.

若わかい人ひとの中なかには、この政党せいとうを支持しじしている人ひともいる。 — Some young people support this party. (neutral-formal, news style) 私わたしはその案あんを支持しじします。 — I support that proposal. (polite, a meeting) 内閣ないかくの支持率しじりつが下さがった。 — The cabinet's approval rating dropped. (内閣ないかく = the cabinet, 支持率しじりつ = approval rating, news)

The noun forms 支持者しじしゃ (a politician's supporter) and 支持率しじりつ appear in Japanese news constantly.

What does サポート cover?

サポート is a katakana loanword for help that keeps something working. It is most common in business and IT, but not limited to them. サポート means helping someone do or use something; it can also be emotional, as in 精神的せいしんてきなサポート.

カスタマーサポートに電話でんわした。 — I called customer support. (neutral, the standard business term) 引っ越ひっこし業者ぎょうしゃに荷造にづくりのサポートをお願ねがいした。 — I asked the moving company for help with packing. (polite, a paid service; for a friend you would say 手伝てつだってもらった) このソフトは来年らいねんサポートが終おわる。 — This software loses support next year. (technical support lifecycle)

支援しえん sits next to サポート but is more formal and organizational. It covers money and goods, and also counseling, job help, and similar aid: 被災地ひさいちを支援しえんする, 就労しゅうろう支援しえん.

Beyond the basics

How do you tell 支持しじ from 自信じしん?

支持しじ (しじ) and 自信じしん (じしん) are not the same sounds reordered, but they are close enough in sound for a learner to mix up in fast speech. Decide by meaning: 支持しじ is agreeing with and backing something, and 自信じしん is confidence in yourself or your ability.

彼かれはその意見いけんを支持しじしている。 — He backs that opinion. (支持しじ = しじ, two beats) 彼かれは自分じぶんの意見いけんに自信じしんがある。 — He is confident in his own opinion. (自信じしん = じしん, three beats)

Don't sort them by the verb. Both can appear with ある/ない, since 支持しじがある and 支持しじを失うしなう are possible, and 指示しじ (しじ, instruction) is an exact homophone of 支持しじ. Check the meaning and the context; your own confidence is 自信じしん, and a third party's agreement is 支持しじ. For the confidence side see 自信じしん and "confidence" in Japanese.

What do people actually say instead of "I support you"?

People say 応援おうえんしてるよ or 味方みかただよ much more naturally than あなたを支持しじします. 応援おうえんしてるよ ("I'm rooting for you") is the everyday line, and 味方みかただよ ("I'm on your side") says you will stand with the person.

応援おうえんしてるよ。頑張がんばって。 — I'm rooting for you. Do your best. (casual, friends) 何なにがあっても、私わたしはあなたの味方みかただよ。 — No matter what happens, I'm on your side. (warm, a little dramatic) ずっと応援おうえんしてるからね。 — I'll be cheering for you the whole time. (casual, からね adds reassurance)

味方みかた is stronger than 応援おうえん because it is about standing with someone against pressure. It is common in anime, usually when a character has been left alone, and its opposite is 敵てき (てき, enemy). Among friends it is also used lightly: 私わたしは君くんの味方みかただからね can be a gentle reassurance. For the word you say right before a challenge, see 頑張がんばって.

Which form do you write in a message: 応援おうえんしてる or 応援おうえんしています?

The choice is register. 応援おうえんしている is the plain form, 応援おうえんしています the polite one, and in speech each loses its い: ている becomes てる, ています becomes てます. 応援おうえんしています suits fan letters and people you don't know; 応援おうえんしてる suits friends.

ライブ、楽たのしみにしています。これからも応援おうえんしています。 — I'm looking forward to the concert. I'll keep supporting you. (polite, a message to a performer) 応援おうえんしてます! — I'm cheering for you! (polite-casual, the contracted polite form, common in comments) 応援おうえんしてるよ! — I'm rooting for you! (casual, friends and family)

The 〜ている form here is not "right now": it expresses a continuing feeling, so 応援おうえんしています means "I'm behind you".

What about 助たすける and 手伝てつだう?

助たすける (たすける) is "to help or rescue" and 手伝てつだう (てつだう) is "to lend a hand with a task". They overlap with サポート when you are doing the helping. The full comparison is in help in Japanese.

Common mistakes

  • Choosing 支持しじ for a friend's dream. 先輩せんぱいの夢ゆめを支持しじします sounds like an endorsement. To encourage a senior, say 先輩せんぱいの夢ゆめを応援おうえんしています.
  • Choosing サポートします to cheer for a team. チームをサポートします sounds like a sponsor or staff member talking. Say チームを応援おうえんします for a fan.
  • Using 応援おうえん for a task someone needs done. 資料しりょう作つくりを応援おうえんします only says you are rooting for the work. If you will do part of it, say 資料しりょう作つくりを手伝てつだいます or サポートします.

Practice

Build each answer before opening it. Questions 5 and 6 are a pair: same kind of sentence, a different meaning.

1. Tell a friend, casually, that you're rooting for them before a speech.

Show answer

スピーチ、応援おうえんしてるね — 応援おうえんする in the casual form; ね adds a friendly tone.

2. A fan comment under a streamer's video: "I'll keep supporting you" (polite).

Show answer

これからも応援おうえんしています — the polite 〜ています form is the safe choice for someone you don't know.

3. "Most residents support the plan to build a new bus line." Which verb?

Show answer

住民じゅうみんの大半たいはんが、バス路線ろせんの新設計しんせっけい画がを支持しじしている — agreeing with and backing a plan is 支持しじ, not 応援おうえん.

4. Your company has a phone line for users with problems. What is it called?

Show answer

カスタマーサポート — help with a practical problem is サポート, usually in katakana.

5. "He has no confidence in his plan." Choose 支持しじ or 自信じしん.

Show answer

彼かれは自分じぶんの計画けいかくに自信じしんがない — 自信じしん (じしん) is his own confidence in himself.

6. "The voters have stopped backing his plan." Choose 支持しじ or 自信じしん.

Show answer

有権者ゆうけんしゃは彼かれの計画けいかくを支持しじしなくなった — 有権者ゆうけんしゃ (ゆうけんしゃ, voters) agreeing or not is 支持しじ (しじ), a third party's backing.

7. A shelf stays up because of one bracket. Which verb describes what the bracket does?

Show answer

支ささえる — 金具かなぐが棚たなを支ささえている. 支ささえる covers physical weight as well as emotional weight.

8. Encourage a senior who is applying for a hard exam, warmly. What do you say?

Show answer

先輩せんぱいの合格ごうかくを応援おうえんしています — encouraging a person's goal is 応援おうえん. 支持しじ would sound like backing a policy.

9. A friend says 何なにがあっても味方みかただよ after a tough week. What is the feeling?

Show answer

"I'm on your side no matter what" — 味方みかた is a promise to stand with you, stronger than 応援おうえん.

10. Thank your family for emotionally holding you up through a hard year.

Show answer

いつも支ささえてくれてありがとう — 支ささえてくれる is the natural way to thank someone who held you up.

FAQ

How do I thank people for their support? It depends on the kind. For cheering, 応援おうえんありがとうございます. For a friend or family member who held you up, いつも支ささえてくれてありがとう. For a politician's or organization's backers, ご支持しじありがとうございます is the formal fixed phrase, and 支持しじありがとうございます alone sounds clipped.

Can I say 応援おうえんしています to my boss or teacher? 応援おうえんしています is a polite form and is often used with teachers and seniors, but it depends on the relationship and the situation. If the person is facing a big challenge, 応援おうえんしております is more formal.

What does サポーター mean? In Japanese, サポーター most often means a club's fan, as in the Japanese national team's サポーター. It can also mean a physical support brace worn on a knee. The verb for what a fan does is still 応援おうえんする.

How do I say "supporter" for a person? It depends on the kind. 応援おうえんしてくれる人ひと is someone who cheers for you, ファン is a fan, and a politician's backer is a 支持者しじしゃ.
