Japanese Setsubun

Observed each year on 3 February, Setsubun marks the eve of the traditional beginning of spring in Japan, a threshold moment when the old season is driven out and the new one welcomed in. It is a day of roasted soybeans and laughter, of children flinging beans at a parent wearing a fearsome red demon mask while shouting for misfortune to leave and good luck to enter. Behind the playful chaos lies an old and serious idea: that the turning of the seasons is a vulnerable, liminal time, when ill fortune must be deliberately swept away. Setsubun captures something universal, the human urge to make a clean start, dressed in the warmth and humour of Japanese custom.
1 Origins
Setsubun, whose name means roughly “seasonal division”, originally referred to the eve of any of the four seasonal turning points in the old lunisolar calendar. Over time the term came to be associated above all with the start of spring, the most significant of these transitions, which in the traditional reckoning fell close to the beginning of February. The bean-throwing ritual draws on older purification customs and on beliefs, influenced by Chinese practice, that the boundaries between seasons were moments when evil spirits could intrude and needed to be expelled.
2 History
The observance has roots stretching back many centuries, with bean-scattering rites recorded at the imperial court and later spreading among ordinary households and temples. The ritual blends folk belief with elements of Buddhist and Shinto practice, and its precise forms have varied across regions and eras. What endured was the central act of casting out misfortune at the cusp of spring, a custom robust enough to survive successive calendar reforms and to remain firmly fixed in the popular calendar today.
3 Why It Matters
Setsubun matters as a vivid expression of a deep cultural instinct: to mark transitions with ritual and to take active, symbolic steps to invite good fortune. It is also a rare festival that places children at its heart, turning an ancient idea about cosmic order into a joyful family game. In doing so it passes tradition gently from one generation to the next, keeping old beliefs alive not through solemnity but through shared laughter and the satisfying rattle of beans across the floor.
4 How It Is Celebrated
The best-known custom is mamemaki, the scattering of roasted soybeans. A family member, often the father, dons an oni (demon) mask, while others throw beans at him crying “Oni wa soto! Fuku wa uchi!”, meaning “Demons out! Fortune in!” Afterwards, it is traditional to eat a number of beans equal to one’s age, plus sometimes one more, to secure health for the year. Temples and shrines hold larger public events where dignitaries and celebrities toss beans, and increasingly sweets, to eager crowds.
5 Traditions and Symbols
The roasted soybean is the festival’s central symbol, valued both as a missile against misfortune and as a token of good health when eaten. The red-faced oni mask embodies the bad luck and malign spirits to be repelled. Another custom, especially in western Japan and now spread more widely, is eating an ehomaki, an uncut sushi roll consumed in silence while facing a lucky compass direction set for the year, a more recent tradition that has become popular nationwide.
6 Around the World
Setsubun is distinctly Japanese, yet its underlying spirit echoes seasonal-threshold customs found across many cultures, from spring-cleaning rituals to festivals that drive out winter and welcome renewal. Wherever the Japanese diaspora has settled, families and community groups keep the bean-throwing alive, and temples abroad sometimes host their own celebrations. For many outside Japan, Setsubun offers an inviting window onto how the country marks the rhythm of its seasons.
7 Fun Facts
The number of beans one eats is tied directly to one’s age, so the ritual doubles as a quiet annual reckoning of the years. The ehomaki tradition, now widely commercialised, requires the roll to be eaten whole and uncut, symbolising unbroken good fortune, and in silence to keep the luck from escaping. And while soybeans are most common, some snowy northern regions traditionally throw roasted peanuts instead, being easier to find and tidy up.
8 A Closing Reflection
Setsubun reminds us that the changing of the seasons has always felt momentous, a time to clear away the old and make room for the new. In its mix of ancient belief and family fun, it shows how tradition survives best when it can still raise a smile. To scatter beans on 3 February is to take part in a very old, very human hope: that misfortune can be sent packing, and that spring, and good luck, may be invited gently in.
