Then, let’s check how to express your blessing, and say “happy birthday” in Japanese.

How to say Happy Birthday in Japanese?


o tanjoubi omedetou gozaimasu!

”O tanjoubi omedetou gozaimasu” is a polite way to give someone wishes on their birthday. It sounds quite long, right? Let me break this sentence down and have a simple explanation of every part.

誕生日 (hiragana: たんじょうび, tanjoubi) is a noun which means birthday. 

The お (o) in front of 誕生日 is one of Japanese honorific prefixes, another one is ご (go). お and ご are used to add feeling of politeness or respect to a word.

おめでとうございます (omedetou gozaimasu) means congratulations. It can be used on almost all occasions when you want to congratulate someone. ございます is a very polite expression in the discussion of 敬語 (keigo). Keigo is a polite form that Japanese use to convey respect. Japanese society has always emphasized hierarchy, therefore, keigo is used when talking with your professor, boss, client, and people you are not close to.

Below are two phrases that you might already know that are attached with gozaimasu.

  • ありがとうございます。 (arigatou gozaimasu) Thank you very much.
  • おはようございます。  (ohayou gozaimasu) Good morning.

On the other hand, during conversation with people close to you, it is allowed to say without ございます. 

  • ありがとう。
  • おはよう。
  • おめでとう。

Japanese Tradition

You might have already learned about some famous festivals held to ask for blessings from God in shrines or temples. There are also few traditional rites during a person’s life when turning to a certain age. Let’s take a look at two widely known traditions.

七五三 (Shichi-Go-San)

Shichi-go-san, literally translates to “Seven Five Three”, is a traditional rite usually held on November 15 for girls aged seven and three and boys aged five and three. 

There are several views on the origin of this tradition. One of the stories indicates that this tradition is quite long and can be dated all the way back to the Muromachi Period (1336-1573). At that time, due to the high infant mortality rate, children were not recognized as a member in the family until three years old. From then on, the ceremony developed, and gained popularity, spreading throughout Japan. 

Nowadays, shichi-go-san is to celebrate a child’s growth and good health, and it is also a way for parents to thank the gods. On the day, children are dressed in kimonos and taken to shrines to pray for health and a long, blessing life. They are also given 千歳飴 (chitose ame), literally a thousand years candy, to wish for a thousand years of health.

Coming of Age Day 成人式 (Seijin Shiki)

Another important tradition concerned with birthdays is Coming of Age day. This is an event held on the second Monday of January annually for the youth who turned 20 since the previous April and who are going to turn 20 years old before April in that year. In other words, it is held in the sophomore year. Everyone celebrates reaching their adulthood in kimonos or suits.

I am 20 years old.

20 is pronounced “nijuu” in Japanese. However, there is one fact that you need to remember, when Japanese say “I am twenty years old”, they normally say “hatachi desu” instead of “nijuu sai desu”. We can’t claim the mistake here, but “hatachi” is the way people use.


Perhaps you have already started your life in Japan or you are carrying on with it. Wherever you are, I am sure you are doing your best to learn everything about this language and this country! Next time when your Japanese friends are having their birthday, don’t forget to say “o tanjoubi omedetou gozaimasu”!
