Japanese Wedding Etiquette: A Complete Guide for International Guests

Introduction: Invited to a Japanese Wedding? Here’s What You Need to Know

If you’re an expat in Japan or a foreign friend invited by a Japanese couple, you’re probably wondering: “How much should I give? What’s a ‘crisp new bill’? What’s the dress code? How do I fill out the RSVP card?”

These are the same questions every foreigner asks before their first Japanese wedding. Drawing on Nippon.com, Savvy Tokyo, and Japan Living Guide, this article walks through Japanese wedding etiquette across four practical axes: gift money, dress code, RSVP, and the day-of timeline. Even Japanese guests sometimes get the details wrong – we’ll cover those too.

Bottom Line: Three Things You Must Get Right

If you remember nothing else, focus on these three: “¥30,000 in new crisp bills, no full white outfit (women), and RSVP within a week.” Get these right and small mistakes elsewhere will be forgiven as “the foreigner is doing their best.”

Gift Money Amounts

The amount of goshugi (御祝儀) depends on your relationship to the couple. According to a Japan Today 2025 survey, more young Japanese feel ¥30,000 is “too expensive,” but the official etiquette remains as below.

Why “Odd Numbers”

Odd numbers are not divisible – symbolically, the couple won’t “split.” So 3, 5, or 7 ten-thousand-yen bills. ¥100,000 and ¥200,000 are exceptions because Japanese culture treats them as “round milestones.”

Why ¥40,000 and ¥90,000 Are Forbidden

“4” sounds like “death” (shi) in Japanese, and “9” sounds like “suffering” (ku). At a celebration, these are absolutely off-limits with no exceptions. A Japanese guest seeing them would feel genuinely uncomfortable.

Envelope Selection and Presentation

Picking the Right Envelope

Available at convenience stores, department stores, and 100-yen shops (Daiso, Seria). Look for an envelope marked for “Wedding” with a “musubikiri” knot (a one-time-only knot – meaning “may this happen only once,” i.e., never divorce). Avoid the “chochoumusubi” (re-tie-able knot) used for births.

Envelope Quality by Amount

For ¥30,000, a simple ¥1,000 envelope is fine. For ¥50,000+, choose a ¥3,000 formal envelope. For ¥100,000+, the most formal ¥5,000-10,000 envelope.

Where to Get Crisp New Bills

Ask at any bank counter (Mitsubishi UFJ, Mizuho, SMBC) for “shinsatsu ni koukan shite kudasai” (please exchange for new bills). Free service. ATMs do not give new bills – you must visit a bank counter. Do this 3 days before the wedding at the latest.

Writing on the Envelope

Write “Kotobuki” (寿) or “Goshugi” (御祝) on the top center with a black brush pen (fudepen). Write your full name underneath. The inner envelope needs the amount in formal kanji (“金壱萬円” for ¥10,000) and your address and name. Pencil and ballpoint pen are not acceptable – always use a black brush pen.

Dress Code

For Women

Pastel colors, navy, or beige formal dresses. Absolutely off limits: full white (the bride’s color), excessive skin, miniskirts, black tights, fur (associated with killing), unnatural materials. Pearls are OK; sandals are not.

For Men

Black or dark suit + white shirt + silver or white tie. Absolutely off limits: black tie (funeral color), denim, jeans, sneakers, short-sleeved shirts. Black leather shoes only.

If You’re a Foreigner

Western formal wear (tuxedo, evening dress) is welcome if you’re from a Western country. A red qipao for Chinese guests is also fine. The principle is “elegant but not more glamorous than the bride and groom.”

Filling Out the RSVP Postcard

Reply Within a Week

The invitation (shotaijo) comes with a return postcard (henshin hagaki). Reply within 2-3 days, or 1 week max. This is among the most important rules in Japanese business etiquette.

Quirky Marking Rules

Strike through the “iki” (行) on the address label and write “sama” (様) next to it. Strike through the polite “go” (ご) before “shusseki” (出席, attendance) and circle “shusseki.” Do the same for “go-jusho” (ご住所) and “go-houmei” (ご芳名). This Japanese humility convention is very specific.

Day-of Flow

Ceremony and Reception Timeline

Ceremony: 11:00 (about 30 min). Reception: 12:00-15:00 (3 hours). Reception desk: 11:30-12:00 – hand over the goshugi and sign the guestbook. The point most people miss: arrive 20 minutes early.

Greeting at the Reception Desk

Say “Honjitsu wa omedetou gozaimasu. Shinrou XX no yuujin/douryou no XX desu.” (Congratulations on the day. I’m a friend/colleague of the groom XX, my name is XX.) Take the goshugi out of a fukusa (folded silk pouch) and present it with both hands. A clean handkerchief works if you don’t have a fukusa.

If You’re Asked to Give a Speech

As a foreigner, take extra care to avoid “imikotoba” (taboo words): “wakareru” (separate), “kireru” (cut), “owaru” (end), “saigo” (last). 3-5 minutes is standard. The classic structure: a story about the couple + your relationship + best wishes for the future.

Wedding Ceremony Types in Japan

Shinto Ceremony (at a shrine)

Traditional ceremonies at shrines like Meiji Jingu or Ise Jingu. The couple wears traditional Japanese attire (shiromuku or montsuki hakama). Guests can wear either traditional or Western formalwear. The san-san-kudo sake-sharing ritual is sacred – watch quietly without flash photography.

Christian-Style Ceremony

The most popular style today. Hymns, scripture, vows, ring exchange. You don’t need to be Christian to attend or even hold the ceremony – it’s essentially a Western-style wedding format.

Civil/Friends Ceremony (jinzenshiki)

No religious elements – all guests serve as witnesses. The couple states their vows and a guest representative serves as official witness. The most casual and easy for international guests.

Buddhist Ceremony (rare)

Held at Buddhist temples, especially in Kyoto. Incense ritual is part of the ceremony – learn the basics in advance.

Common Misconceptions

Misconception 1: A Smaller Amount Is Polite

Wrong – a smaller amount is rude. ¥30,000 is the floor for a friend; less than that is considered cheap. Even if you’re in your 20s and tight on money, ¥30,000 is the minimum.

Misconception 2: A Cash-Bar Reception Means No Goshugi

In Hokkaido and at younger couples’ weddings, “kaihi-sei” (cash-bar admission, ¥15,000-20,000) replaces goshugi. Confirm with the couple before deciding.

Misconception 3: A Gift Replaces Cash

No. Gifts and cash are separate. Either bring both or just give cash. Gifts are sometimes sent separately after asking the couple about preferences.

FAQ

Q1. What if I’m only attending the after-party?

Just pay the after-party entry fee (¥5,000-10,000). No goshugi needed.

Q2. How do I decline politely?

Circle “kesseki” (decline) on the RSVP and add “yamuwoezu kesseki” (regrettably unable to attend) in the notes. Send a ¥5,000-10,000 telegram or gift afterward.

Q3. What if I bought the wrong envelope?

You can return the chochoumusubi (wrong) and exchange for musubikiri (correct) at department stores or convenience stores with a receipt.
