To wish someone a happy birthday in polite Japanese, the standard phrase is: お誕生日おめでとう! (otanjōbi omedetō!)

Breakdown:

  • お(o-): A polite prefix (similar to “Mr.” or “Ms.”)
  • 誕生日(tanjōbi): Birthday
  • おめでとう(omedetō): Literally “good fortune,” used for celebrations

Common complete birthday greeting: 👉 お誕生日おめでとう! (otanjōbi omedetō!) — Happy Birthday! For a longer, expressive wish: 👉 お誕生日おめでとうございます! (otanjōbi omedetō gozaimasu!) — A more formal and heartfelt “Happy Birthday.”

A popular (and slightly dramatic) birthday cake trend is the kuro nori kaēki — a cake layered with dark chocolate or black buttercream to symbolize maturity and progress.

In workplaces or school groups, birthdays may be celebrated with banda (parties), mochi (rice cakes), and group toasts — symbolizing unity and support.

  • Family Surprising: Close relatives often organize a special meal or outing.
  • Omotenashi Service: Service staff at restaurants or shops may offer personalized birthday treats.
