How To Say Happy Birthday in Japanese

1. Otanjoubi omedetou — Happy birthday (casual)

Japanese: お誕生日おめでとう
(おたんじょうびおめでとう)

This is the most common, one-size-fits all way to say “happy birthday” in Japanese.

If you’re a good friend or family member of the person turning a year older, you can save yourself a few syllables and leave off gozaimasu, or even the “o” in otanjoubi. This phrase implies a more casual, familiar vibe between the speaker and the listener.

Otanjoubi omedetou. Paatii o tanoshimi kudasai. — Happy birthday. Enjoy your party.

Japanese: お誕生日おめでとう。パーティーをお楽しみください。
(おたんじょうびおめでとう。ぱーてぃーおたのしみください。)

2. Otanjoubi omedetou gozaimasu — Happy birthday (formal)

Japanese: お誕生日おめでとうございます
(おたんじょうびおめでとうございます)

This phrase is the most polite way to give someone well wishes on their birthday. It’s a form of keigo, 敬語(けいご)— polite speech, a cornerstone of speaking the Japanese language.

This is a good option if you don’t know the person very well or if you want to show them respect.

Yamada-san, otanjoubi omedetou gosaimasu. Korekara mo Genki de ite kudasai. — Happy birthday, Mr. Yamada. Please continue to stay healthy.

Japanese: 山田さん、お誕生日おめでとうございます。これからも元気でいてください。
(やまださん、おたんじょうびおめでとうございます。これからもげんきでいてください。)

3.  Ota ome — Happy birthday (abbreviated slang)

Japanese: おたおめ 

You may have noticed that the more formal a phrase is, the longer it becomes as polite speech is added on to it.

The reverse is also true! Shortening otanjoubi omedetou, you get the super-snappy ota ome. This version of “happy birthday” is slang that’s used only in very casual settings, especially online, and is generally used more by the younger generation.

Ossu! Ota Ome! Nomi ni ikou. — Hey man! Happy birthday! Let’s go out for drinks.

Japanese: おっす!おたおめ! 飲みに行こう。
(おっす!おたおめ!のみにいこう。)

4.  〇〇-sai no otanjoubi omedetou — Happy Xth birthday

Japanese: 〇〇歳のお誕生日おめでとう。
(〇〇さいのおたんじょうびおめでとう。)

Is someone celebrating an important year? Or maybe you want to be more specific in your birthday wishes. In that case, use this phrase, which allows you to input the specific age someone is turning.

Note that although you’re technically counting in ordinal numbers (first, second, third… birthdays), you use the cardinal readings of Japanese numbers here (issai, nisai, sansai… no otanjoubi).

Jyuu hassai no o tanjoubi omedetou. Mou otona desu! — Happy 18th birthday. You’re an adult now!

Japanese: 18歳のお誕生日おめでとう。もう大人です!
(じゅうはっさいのおたんじょうびおめでとう。もうおとなです!)

5. Happii baasudee — Happy birthday

Japanese: ハッピーバースデー
(はっぴーばーすでー)

Given how loanwords are fairly common in the Japanese language, this one shouldn’t be much of a surprise! You can even mix and match and say, happii otanjoubi.

And, of course, the happy birthday song in Japanese might be easier to sing than you think!

Happii Baasudee tu yuu! — Happy birthday to you!

Japanese: ハッピーバースデー トゥーユー!
(はっぴーばーすでーとぅーゆー!)

6.  Osoku nattakedo, otanjoubi omedetou! — Happy belated birthday!

Japanese: 遅くなったけど、お誕生日おめでとう!
(おそく なったけど、おたんじょうびおめでとう!)

If you missed your friend’s birthday, don’t sweat it! Just wish them a belated happy birthday in Japanese, just as you might in English. The key phrase here is Osoku nattakedo… (Though it’s late…) and you can follow it up with a birthday wish of whatever formality suits the occasion.

Osoku nattakedo, otanjoubi omedetou! Suimasen okuremashita. — Happy belated birthday! I’m sorry I’m late.

Japanese: 遅くなったけど、お誕生日おめでとう!すいません、遅れました。
(おそく なったけど、おたんじょうびおめでとう!すいません、おくれました。)

7. Suteki na ichinen ni narimasu youni — I hope this will be a wonderful year

Japanese: 素敵な一年になりますように
(すてきな いちねん に なります よう に)

Add this statement to your birthday wishes to make it even more heartfelt and meaningful. You can use this with anyone—it’s suitable for any level of formality, from your boss to your best friend!

Otanjoubi omedetou! Suteki na ichinen ni narimasu youni! — Happy birthday! I hope this will be a wonderful year!

Japanese: お誕生日おめでとう!素敵な一年になりますように!
(おたんじょうびおめでとう! すてきな いちねん に なります よう に!)

Japanese Birthday Etiquette and Customs

Just like in English, it can be a bit too straightforward to ask for someone’s age on their birthday.

But you can definitely ask about their birthday wishes!

Because of customs like this, it’s extremely important you understand basic cultural etiquette before attending a Japanese birthday party.

Don’t touch someone else’s gifts:

Here’s a word of advice: don’t touch or open someone else’s gift.

That’s a worldwide no-no!

There’s a proper way to give gifts:

If you have a gift to offer the birthday person, you should give it to them properly.

In Japanese culture, you should always hand someone a gift with both hands and a slight bow. Don’t be surprised if the person rejects the gift once or twice, either. This is just a way of being humble and polite.

Just like how you gave the gift with both hands and a bow, eventually, your Japanese colleague or friend will also receive the gift with both hands and a slight bow.

Birthdays change as you get older:

As a child, your parents will throw a party for you. As you get older though, different people of importance in your life will start to take charge.

For example: In high school, if a young shounen 少年(しょうねん)(male) has a girlfriend, he’d be the one to take her out for her birthday.

And if you’re single, your friends are more likely to take you out or throw a birthday bash to honor you.

Special birthdays in Japanese culture:

In Japan, you’re considered an adult when you turn 18. (This was recently lowered from 20!) It’s also the age you can start to legally drink alcohol and are allowed to vote. So it only makes sense that someone’s 18th birthday is cause for a big celebration.

Your 16th birthday is also a big one, though. When a person turns 16, the five cycles of the Chinese zodiac are completed. The person is then considered “reborn.”

The last birthdays to be hyper-aware about are the 77th birthday, 88th and the 99th:

  • The “happy age” is your 77th birthday
  • The “rice age” is your 88th birthday
  • The “white age” is your 99th birthday

 

And there you have it, your all-in-one guide for celebrating birthdays in Japan and using different, colorful expressions for saying “happy birthday” in Japanese!

So the next time you go to Japan, or when your Japanese language exchange partner’s special day approaches, pick from your new collection of phrases wisely.
