Birthdays in Japan blend traditional and modern elements, and knowing how to wish someone well in Japanese can deepen your connection, whether it’s with a friend, coworker, or someone special. Plus, it’s a fun way to dip your toes into learning Japanese!
The Standard Way to Say “Happy Birthday”
The most common and versatile way to say “happy birthday” in Japanese is:
- お誕生日おめでとう (Otanjoubi omedetou)
This phrase works in most situations—think of it as your all-purpose birthday greeting. Here’s the breakdown:
- お誕生日 (Otanjoubi): “Birthday” (the “o” adds politeness).
- おめでとう (Omedetou): “Congratulations.”
Together, it translates to “Congratulations on your birthday,” which might sound formal in English but is a natural way to celebrate in Japanese. You can use this with friends, acquaintances, or even someone you don’t know well.
For an extra polite twist, add ございます (gozaimasu):
- お誕生日おめでとうございます (Otanjoubi omedetou gozaimasu)
This version is perfect for formal settings, like wishing a teacher or boss a happy birthday.
Formal vs. Informal Variations
Japanese is all about context—your relationship with the person and the setting dictate how formal your greeting should be. Here are the main variations:
Casual and Informal Options
For close friends or family, keep it light and friendly:
- 誕生日おめでとう (Tanjoubi omedetou)
Drops the “o” prefix for a more relaxed vibe. Use this with people you’re comfortable with. - おめでとう (Omedetou)
Super casual—just “congratulations.” It’s shorthand, so use it at a party or with buddies who’ll get the context. - ハッピーバースデー (Happii baasudee)
This is “Happy Birthday” borrowed from English, popular among younger folks or in casual, Western-style celebrations.
Formal and Polite Options
For elders, coworkers, or formal occasions:
- お誕生日おめでとうございます (Otanjoubi omedetou gozaimasu)
The polite standard—safe for professional or respectful situations. - ご誕生おめでとうございます (Go tanjou omedetou gozaimasu)
Ultra-formal, often seen in writing or speeches. Great for someone you deeply respect.
Fun and Festive Twist
Want to stand out? Try:
- お誕生日おめでたい (Otanjoubi omedetai)
“Omedetai” means “joyous” or “auspicious,” adding a celebratory flair.
Pronunciation Made Simple
Japanese pronunciation is straightforward once you get the hang of it. Each syllable is pronounced clearly, and stress is minimal. Here’s how to say the key phrases (imagine saying them slowly, like “oh-tan-joe-bee”):
- お誕生日おめでとう (Otanjoubi omedetou)
Pronunciation: oh-tahn-joh-bee oh-meh-deh-toh
Tip: The “u” in “jou” and “tou” is soft—almost silent. - お誕生日おめでとうございます (Otanjoubi omedetou gozaimasu)
Pronunciation: oh-tahn-joh-bee oh-meh-deh-toh goh-zai-mahs
Tip: “Gozaimasu” flows together naturally. - 誕生日おめでとう (Tanjoubi omedetou)
Pronunciation: tahn-joh-bee oh-meh-deh-toh - おめでとう (Omedetou)
Pronunciation: oh-meh-deh-toh - ハッピーバースデー (Happii baasudee)
Pronunciation: hah-pee bah-soo-deh
Tip: Sounds like English but with a Japanese twist!
Practice by saying these out loud. If you can, find audio clips online or mimic a native speaker to nail the rhythm.
When and How to Use These Phrases
Choosing the right phrase depends on who you’re talking to and where you are. Here’s a quick rundown:
- お誕生日おめでとう: Friends, casual acquaintances—your everyday go-to.
- お誕生日おめでとうございます: Boss, teacher, elder—anytime you need to be polite.
- 誕生日おめでとう: Close friends, siblings—keep it chill.
- おめでとう: Besties at a party—short and sweet.
- ハッピーバースデー: Kids, teens, or a fun, modern vibe.
In Japan, adding the person’s name makes it personal. For example:
- 佐藤さん、お誕生日おめでとうございます (Satou-san, otanjoubi omedetou gozaimasu)
“Mr./Ms. Sato, happy birthday!” (Polite) - みさちゃん、誕生日おめでとう (Misa-chan, tanjoubi omedetou)
“Misa, happy birthday!” (Casual)
Extra Birthday Vocabulary
Spice up your greeting with these handy words:
- 誕生日 (tanjoubi): Birthday
- ケーキ (keeki): Cake
- プレゼント (purezento): Gift
- パーティー (paatii): Party
- お祝い (oiwai): Celebration
- 幸せな誕生日を (Shiawase na tanjoubi o): “Have a happy birthday.”

Mix and match for a custom message:

Japanese Birthday Customs
Birthdays in Japan mix old traditions with modern flair. Historically, everyone “aged” together on New Year’s Day, but today, individual birthdays are celebrated, especially among kids and young adults. Here’s what to know:
- Cakes: The classic is a fluffy strawberry shortcake—light, creamy, and topped with fruit.
- Gifts: Presentation matters—gifts are wrapped neatly. Avoid giving four or nine of anything (they’re unlucky numbers tied to “death” and “suffering”).
- Parties: Often small, with family or friends, featuring food and laughter.
- Milestones: Age 20 (adulthood), 60 (a full zodiac cycle), and long-life ages like 88 are big deals.
Knowing these adds depth to your greeting and shows cultural savvy.
