How To Say Happy Birthday In Japanese

Ready to make someone's birthday extra special? Let's dive into these Japanese birthday greetings!

ใŠ่ช•็”Ÿๆ—ฅใŠใ‚ใงใจใ†ใ”ใ–ใ„ใพใ™ โ€“ Otanjoubi omedetou gozaimasu

It's the most polite way to say "Happy Birthday," and it's your go-to when you want to show respect or when you're not super close with the birthday person.

Let's break it down:

  • ใŠ่ช•็”Ÿๆ—ฅ (otanjoubi) means "birthday"
  • ใŠใ‚ใงใจใ† (omedetou) means "congratulations"
  • ใ”ใ–ใ„ใพใ™ (gozaimasu) is a polite suffix that elevates the whole expression

This phrase is a perfect example of keigo (ๆ•ฌ่ชž), the Japanese language's system of polite speech. If you've ever used ใ‚ใ‚ŠใŒใจใ†ใ”ใ–ใ„ใพใ™ (arigatou gozaimasu) to say "thank you very much," you're already familiar with how ใ”ใ–ใ„ใพใ™ works to make things extra polite.

In my experience, this is best used when you want to err on the side of formality like during work interactions or when speaking with someone older or of higher authority.

ใŠ ่ช•็”Ÿ ๆ—ฅ ใŠใ‚ใงใจใ† โ€“ Otanjoubi omedetou

ใŠ ่ช•็”Ÿ ๆ—ฅ ใŠใ‚ใงใจใ† (Otanjoubi omedetou) is the standard, casual way to say "Happy Birthday" in Japanese. It's perfect for friends and family. Think of it as the equivalent of a warm, friendly "Happy Birthday!" in English.

When to use it:

  • With your buddies
  • Talking to classmates or coworkers you're close with
  • Family gatherings
  • Any situation where you don't need to be overly formal
Pro tip: Using this version with people who you want to be really close with can also show that you're comfortable with them and understand the nuances of Japanese social dynamics.

ใƒใƒƒใƒ”ใƒผใƒใƒผใ‚นใƒ‡ใƒผ โ€“ Happii baasudee

This phrase is super popular, especially with the younger crowd. When I was teaching in Japan, I heard my students use it all the time. It's written in katakana alphabet script (those blocky characters for foreign words), but get this - on social media, kids often just type "Happy Birthday" in the regular Roman Alphabet.

[ๆ•ฐๅญ—]-ๆญณใฎใŠ่ช•็”Ÿๆ—ฅใŠใ‚ใงใจใ† - [Number]-sai no otanjoubi omedetou

This phrase is your go-to when you want to give a shout-out to someone's specific age. It's like saying "Happy 30th birthday!" instead of just "Happy birthday!" in English. Here's how it works:

  • Replace [ๆ•ฐๅญ—] with the person's age in Japanese.
  • Add ๆญณ (sai) after the number.
  • Finish with ใฎใŠ่ช•็”Ÿๆ—ฅใŠใ‚ใงใจใ† (no otanjoubi omedetou).

For example:

  • 20ๆญณใฎใŠ่ช•็”Ÿๆ—ฅใŠใ‚ใงใจใ† (Hatachi no otanjoubi omedetou) - Happy 20th birthday!
  • 30ๆญณใฎใŠ่ช•็”Ÿๆ—ฅใŠใ‚ใงใจใ† (Sanjussai no otanjoubi omedetou) - Happy 30th birthday!
Quick tip: Even though we're talking about ordinal birthdays (1st, 2nd, 3rd), we use cardinal numbers here. So it's ใ„ใฃใ•ใ„ (issai) for 1, ใซใ•ใ„ (nisai) for 2, ใ•ใ‚“ใ•ใ„ (sansai) for 3, and so on.

่ช•็”Ÿๆ—ฅใŠใ‚ใงใจใ† - Tanjoubi omedetou

In this phrase, we've dropped the polite ใŠ (o) from the beginning of ่ช•็”Ÿๆ—ฅ (tanjoubi). According to my Japanese friends and co-teachers, this basic birthday greeting is a great way to show you're like best friends with the celebrant. Just make sure you're actually close enough to the person before dropping the formalities!

ใŠใŸใŠใ‚ (Ota ome)

This super-short phrase is a condensed version of ใŠใŸใ‚“ใ˜ใ‚‡ใ†ใณใŠใ‚ใงใจใ† (otanjoubi omedetou). It takes the ใŠใŸ (ota) from ใŠใŸใ‚“ใ˜ใ‚‡ใ†ใณ (otanjoubi) and the ใŠใ‚ (ome) from ใŠใ‚ใงใจใ† (omedetou), smooshing them together to create this snappy Japanese birthday party greeting!

When to use it:

  • Online, especially in texts or social media
  • With young, close friends
  • When you want to sound extra casual and cool
Remember, this is seriously informal. Don't use it with anyone older or in any remotely formal situation. It's perfect for a quick birthday text to your bestie, but probably not for your Japanese teacher!

ใŠใ‚ใงใจใ†- Omedetou

Need something really simple? This versatile greeting is actually not just for birthdays - use it for any congratulatory moment since its direct translation is "congrats" in the Japanese language.

้•ทๅฏฟใ‚’็ฅˆใ‚Šใพใ™ โ€“ Chouju o inorimasu

This elegant phrase literally means "I pray for your long life." It's a beautiful way to extend birthday wishes to older adults in Japanese culture. What I perosnally noticed is that this is best used when celebrating a milestone birthday for older adults.

้…ใใชใฃใŸใ‘ใฉใ€ใŠ่ช•็”Ÿๆ—ฅใŠใ‚ใงใจใ† - Osoku nattakedo, otanjoubi omedetou

This phrase is your go-to for belated birthday wishes in Japanese. It literally translates to "Happy belated birthday" The first part, "Osoku nattakedo," means "Although it's become late," and it's the key to turning any birthday wish into a belated one.

Happy Birthday Song In Japanese

Surprising a Japanese friend with the Happy Birthday song in their native language is a delightful way to celebrate their special day. While Japan has embraced the familiar Western melody, they've cleverly adapted the lyrics to suit their language.

Let's break down the lyrics and their pronunciation to help you sing along!

English Japanese (Romaji) Japanese (Hiragana)
Happy Birthday to you Happi Baasudee tu yuu ใฏใฃใดใƒผใฐใƒผใ™ใงใƒผใจใ…ใƒผใ‚†ใƒผ

Usage Tips:

  • Replace [name] with the birthday person's name.
  • Pronounce each syllable clearly, especially the elongated sounds like "baasu" and "yuu".
  • Practice a few times before the big moment to ensure smooth delivery.
  • Remember, it's the thought that counts โ€“ your Japanese friends will appreciate the effort even if the pronunciation isn't perfect!
