Happy Birthday in Japanese: Celebrating Another Year of Life and Joy!
Birthdays in Japan are about more than cake and candles. They’re a chance to say thank you for another year and to show the people around you that you appreciate them. I’ve been lucky enough to see a few Japanese birthdays up close, and the mix of warmth, small gestures and a few very special milestone ages stays with me. In this post I’ll cover how to say happy birthday in Japanese, the traditions behind the day, and some ideas if you’re planning to celebrate in Japan yourself.
How to Say Happy Birthday in Japanese
The standard, polite phrase is お誕生日おめでとうございます (otanjōbi omedetō gozaimasu). It’s safe for coworkers, teachers, elders and anyone you don’t know well.
Casual and Polite Options
- お誕生日おめでとう (otanjōbi omedetō): friendly, for friends and family.
- 誕生日おめでとう (tanjōbi omedetō): even more casual, good for texts and messages.
- お誕生日おめでとうございます: the polite form, as above.
Pronunciation tip: the “jō” in tanjōbi is a long “o” sound, so hold it a little longer than you’d expect.
A Short History of Birthdays in Japan
Celebrating your own birthday on the actual day is a fairly modern habit in Japan. Traditionally, people were counted by kazoedoshi: you were one year old at birth and everyone added a year together at New Year. Western-style individual birthday celebrations spread widely in the twentieth century, helped along by a law that took effect in 1950 encouraging people to count age by birthday. National celebrations of the Emperor’s birthday have a long history too, though the details have changed with each era.
Japanese Birthday Traditions
Gifts
Presents are common, but they tend to be modest and thoughtful rather than extravagant. Flowers, sweets, and small useful items are all popular. Among friends, it’s also common to treat the birthday person to a meal.
Food
Many families mark the day with a favorite home-cooked meal or a restaurant visit. For special occasions you may see sekihan (red rice with azuki beans), sushi, or sea bream (tai), all considered auspicious. Long noodles are linked to long life in Japan, though they’re more strongly tied to New Year than birthdays.
Songs and Parties
Singing “Happy Birthday” is common, often in English. Karaoke rooms are a popular spot for birthday parties with friends, and many restaurants will bring out a dessert plate with a message if you tell them in advance.
Japanese Birthday Cakes
The classic birthday cake in Japan is the light, fluffy strawberry shortcake: sponge, whipped cream and fresh strawberries. You’ll also find matcha, chocolate, cheesecake and, in spring, sakura-flavored versions. Character cakes with anime or favorite-mascot designs are popular for kids, and bakeries often let you order a custom message on a chocolate plate. Prices for a whole cake from a bakery or department store vary a lot by size and shop, so check with the bakery when you order.
Milestone Birthdays in Japan
Coming of Age Day (Seijin no Hi)
Coming of Age Day is a national holiday held on the second Monday of January. Young people turning 20 in that school year dress up (many in colorful furisode kimono) and attend local ceremonies. The legal age of adulthood was lowered to 18 in April 2022, but many towns still hold ceremonies for 20-year-olds, and some have renamed them.
Kanreki (60th Birthday)
Kanreki marks the completion of one full cycle of the traditional 60-year zodiac calendar. It’s seen as a fresh start, and the person is traditionally gifted something red.
Beiju (88th Birthday)
Beiju celebrates the 88th year. The kanji for rice (米) can be read as 八十八, “eighty-eight.” It’s a joyful occasion honoring a long life. There are other longevity birthdays too, such as koki (70) and kiju (77).
Shichi-Go-San
Not quite a birthday, but children aged 3, 5 and 7 are celebrated at shrines around November 15. If you visit Japan in autumn, you may spot kids in kimono.
Birthdays with Family, Friends and Colleagues
Most birthdays are spent with family or close friends, often over a meal. At school, classmates might sing and give handmade cards. At work, colleagues may share a small cake or sweets, or go out together after work. Surprise parties exist, though the simple gesture of a message or a small treat counts for a lot.
Famous Birthdays You Might Run Into
Some birthdays are even national events. April 29th, the birthday of Emperor Hirohito, is now Showa Day, a public holiday and the start of Golden Week. Studio Ghibli’s Hayao Miyazaki was born on January 5th, 1941, and fans around the world celebrate him each year.
Modern Birthday Trends
Themed parties built around favorite shows, characters or hobbies are popular, and so are “oshi” celebrations, where fans mark a favorite idol’s or character’s birthday with cafes, goods and displays. Social media is full of birthday photos and messages too, and some restaurants and shops offer birthday coupons or perks through their apps or membership programs, so it’s worth asking.
Celebrating Your Birthday in Japan
If you’re planning a birthday trip, a few things are worth knowing. Book restaurants and any special dessert plates ahead of time. Spring birthdays can overlap with cherry blossom season, which typically falls from late March to early April in Tokyo and Kyoto, though it shifts each year, so check the forecasts released in the weeks beforehand. For longer trips between cities, a JR Pass can still make sense if you’re covering a lot of ground, but since the October 2023 price increase the 7-day ordinary pass costs 50,000 JPY when bought on the official site (a little more through overseas agents), so compare it with individual tickets first. Note that pass holders need an extra ticket to ride the Nozomi and Mizuho trains. For somewhere memorable to stay on the day, a hotel with a good view is a lovely treat.
FAQ
What is “Happy Birthday” in Japanese?
It’s お誕生日おめでとうございます (otanjōbi omedetō gozaimasu). Drop the “gozaimasu” for friends and family.
How do you pronounce it?
Say “oh-tahn-joh-bee oh-meh-deh-toh goh-zah-ee-mahss,” holding the “jō” and “tō” slightly long.
What gifts are appropriate for a birthday in Japan?
Modest, thoughtful gifts such as flowers, sweets or small useful items are a safe choice. Very expensive gifts can make people uncomfortable.
Are there any birthday superstitions or taboos?
The number 4 (shi, which sounds like “death”) is considered unlucky, so avoid gifts in sets of four. Some traditional yakudoshi (“unlucky years”) are also observed, with shrines and temples offering purification rites. Celebrating before the actual date is sometimes said to be bad luck, but this isn’t a firm rule.
Is the Japanese age system different?
Today, Japan counts age by birthday just like most countries. The older kazoedoshi system is still sometimes used for traditions such as yakudoshi and Shichi-Go-San.
Whatever the occasion, a sincere omedetō goes a long way. If you’re planning a birthday trip, local experiences like cooking classes or guided walks can make the day even more special.
