お誕生日おめでとうございます!” or “O tanjoubi omedetou gozaimasu” is a polite way to wish someone a happy birthday. It sounds pretty long, right? Let me break it down and give you a simple explanation of each part.

誕生日 (hiragana: たんじょうび, tanjoubi) is a noun meaning birthday. The お (o) before 誕生日 is one of the Japanese honorific prefixes, another is ご (go). お and ご are used to add a sense 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 for almost any occasion when you want to congratulate someone. ございます is a very polite expression when discussing 敬語 (keigo). Keigo is a polite form that the Japanese use to convey respect. Japanese society has always emphasized hierarchy, so keigo is used when talking to your professor, boss, customer, 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 a 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。

After knowing the meaning of おめでとうございます, let’s take a look at the form below as well to learn more expressions related to congratulation!

The Japanese Tradition

You may have heard of some famous festivals held at shrines or temples to ask for God’s blessings. There are also a few traditional rites during a person’s life when they reach a certain age. Let’s take a look at two well-known traditions.

1. 七五三 (Shichi-Go-San)

Shichi-go-san, literally translated as “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. According to one story, the tradition is quite old and dates back to the Muromachi period (1336-1573). At that time, due to the high infant mortality rate, children were not recognized as members of the family until they were three years old. From then on, the ceremony developed and gained popularity, spreading throughout Japan.

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

2. 成人式 (Seijin Shiki): Coming of Age Day

Another important tradition related to birthdays is Coming of Age Day. This is an event held on the second Monday of January each year for those youth who have turned 20 since the previous April and who will turn 20 before April of that year. In other words, it is held in the second year. Everyone celebrates reaching adulthood in kimonos or suits.

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


You may already be at the beginning of your life in Japan, or you may still be at the beginning of your life in Japan.

Wherever you are, I am sure you are doing your best to learn about this language and this country! The next time your Japanese friends have a birthday, don’t forget to say “o tanjoubi omedetou gozaimasu”!
