Good Couple Day (Yoi Fūfu no Hi)

What Is Good Couple Day?

Every year on April 22, Japan observes "Yoi Fūfu no Hi" (Good Couple Day). The name comes from a wordplay (goroawase) on the date itself: "yo (4) i fū (2) fu (2)" sounds like "yoi fūfu," meaning "good couple." It isn't an official anniversary established by any government body or company — it's simply a date that became widely recognized because of how naturally the numbers read as that phrase.

The Origin of Good Couple Day

April 22's "Good Couple Day" grew out of Japan's unique culture of turning numbers into words by matching their pronunciations.

• 4 (yo)
• 2 (fu)
• 2 (fu)

Read together, "4-2-2" becomes "yo-fu-fu," which sounds just like "yoi fūfu" — "a good couple." In fact, several other dates use similar number-based wordplay to create couple- or marriage-themed anniversaries.

The Background of Couple-Related Anniversaries in Japan

Japan has a number of anniversaries centered on couples and family life. Many of these were born from this kind of numerical wordplay or from notable social events, and they serve as moments to reflect on married life and family relationships.

Good Couple Day is one such occasion — a milestone in everyday life for thinking about the nature of a couple's relationship.
