A Noisy, Happy Night at the Edge of Spring
Setsubun (節分, “seasonal division”) is the day before risshun (立春), the traditional start of spring on Japan’s old seasonal calendar. It usually lands on February 3, and occasionally on February 2. It is not a public holiday — school and work go on as normal — which is part of its charm: the celebration happens at home after dinner, in pajamas, with whatever beans and masks the family has on hand.
The idea underneath the fun is a fresh start. The turn of the season was long treated as a moment when bad luck could slip in, so families symbolically sweep it out of the house and invite good fortune back in. For kids, though, Setsubun is simpler than that: it is the one night of the year you are allowed to throw food at a grown-up.
If your family is living in Japan, you will see Setsubun everywhere in late January — paper oni masks bundled with bean packets at supermarkets, ehomaki rolls on preorder at convenience stores, and classroom craft projects coming home in backpacks. If you are in the US, it is an easy festival to bring home: the gear is paper, the soundtrack is shouting, and the food is simple. It sits nicely alongside other winter traditions such as Lunar New Year snacks and Japan’s own osechi New Year sweets.
The Three Customs Kids Love
1. Mamemaki: bean throwing
Mamemaki (豆まき, “bean scattering”) is the main event. Traditionally the beans are fukumame (福豆, “fortune beans”) — roasted soybeans. One person, often a parent, plays the oni (鬼), a horned demon or ogre, usually by wearing a paper mask. Kids throw beans toward the oni and out the door while shouting “Oni wa soto!” (demons out), then toss a few inside with “Fuku wa uchi!” (good fortune in). The oni retreats, dramatically defeated. Temples and shrines also hold public bean-throwing events, sometimes with local celebrities tossing small packets to crowds.
Details vary by family and region. In some areas of northern Japan, families throw peanuts in the shell instead of loose soybeans, partly because they are easier to find and clean up afterward — worth knowing if anyone in your home has a peanut allergy.
2. Eating beans by age
After the throwing, many families eat roasted soybeans — one bean for each year of your age, and some add one extra for the year ahead — as a wish for good health in the coming year. Grandparents end up with a handful; a seven-year-old counts out seven with great ceremony. It is a lovely counting ritual, and it is also where the safety question starts, because a toddler watching everyone else eat beans will want theirs too.
3. Ehomaki: the lucky-direction roll
Ehomaki (恵方巻, roughly “lucky-direction roll”) is a thick sushi roll eaten whole, without slicing, while facing that year’s eho, the direction considered auspicious. Many people eat it in silence from start to finish, making a wish. The custom has roots in the Osaka area and spread across Japan in recent decades, helped along by supermarket and convenience-store promotions, so for many families it is a newer layer on top of the much older bean throwing. Fillings vary widely; there is no single required recipe.
The Safety Rule: No Whole Roasted Beans Under 5
Here is the part that changed how many Japanese families celebrate. Roasted soybeans are small, hard, and round — a classic choking shape. Young children do not yet have the molars or the chewing control to grind them, and dry fragments can be inhaled into the airway rather than swallowed. Japan’s Consumer Affairs Agency issues a warning ahead of Setsubun advising parents not to give hard beans and nuts to young children, with its guidance covering kids age 5 and under. It also reminds families that stray beans left on the floor after mamemaki are a hazard for toddlers who find them later.
US guidance points the same way. The American Academy of Pediatrics lists whole nuts, popcorn, hard candy, and other hard, round foods among the choking hazards for children under 4. Our choking prevention guide covers safe sizes and shapes in detail. For Setsubun, that translates into a simple plan:
A Setsubun plan that works for every age
- Throw wrapped, eat soft. Use individually wrapped bean packets (sold in Japan for exactly this reason) or crumpled paper “beans” for throwing. Nothing that hits the floor goes in a mouth.
- Separate throwing from eating. Keep a sealed bowl of eating beans for older kids and adults on the table, away from the throwing zone.
- Sweep and count. Pick up every stray bean or packet the same night, including under sofas and along baseboards.
- Swap the bean, keep the ritual for little ones. Count out the age number with soft foods: mashed or halved edamame for small children, kinako-dusted yogurt bites, or soft tofu cubes.
- Seated and supervised. Even for older kids, eating happens sitting down, one bean at a time — not mid-chase with a mouthful.
Kinako (きな粉, roasted soybean flour) is the easy bridge here: it carries the same toasty roasted-soy flavor as fukumame with none of the hard-pellet risk. Sprinkle it on yogurt, banana slices, or toast — our kinako recipes for kids have more ideas. Edamame is another soybean option that kids already know.
Soy Allergy and Other Practical Notes
Soybeans are one of the major food allergens the FDA requires to be declared on US food labels, and kinako, edamame, tofu, and soy sauce in ehomaki are all soy. If your child has a soy allergy, the throwing can still happen with paper balls or wrapped non-food tokens, and the eating can move to a soy-free snack you already trust. If peanut packets are part of your local tradition, the same thinking applies. When you are unsure about a new food, talk with your pediatrician or allergist first.
For ehomaki, the “eat it whole, without slicing” rule is a grown-up custom, and kids can skip it without missing the meaning. Slice rolls into thin rounds or make small, thin hand rolls, cut fillings into small pieces, and keep little ones seated — nori can be surprisingly hard for young children to bite through, and large mouthfuls of sticky rice are worth avoiding. Kids can still face the lucky direction and make a wish; a compass app turns that into its own small adventure. If your family enjoys rice-based snacks, our onigiri guide has more kid-sized shapes.
Roasted soybeans on their own are just beans: plant protein and fiber with no added sugar, which makes them a sensible snack for older kids and adults who can chew them well. Some shops sell sugar-coated versions; plain roasted beans keep the evening simple.
Family Activities: Masks, Beans, and a Little Theater
Setsubun is mostly a craft-and-play festival, which makes it a gift for families who want to share Japanese culture without a big food project.
- Make paper oni masks. A paper plate, red or blue paper, yarn hair, and two paper horns are all you need. Japanese oni are often drawn red or blue, but kids can invent their own — a grumpy oni, a sleepy oni, an oni afraid of vegetables.
- Name your oni. Many Japanese preschools ask kids which “inner oni” they want to chase away — the crying oni, the picky-eating oni, the stay-up-late oni. It is a gentle way to talk about habits without lecturing.
- Fold a bean box. Origami boxes (masu) make good containers for wrapped bean packets, and older kids can fold one for each family member.
- Count by age. Have kids line up soft snack pieces for each family member’s age. It doubles as quiet math practice.
- Add a sweet from the season. If you want a dessert, a small piece of traditional Japanese confection works well; our wagashi guide explains the basics. Keep any mochi-based sweets cut small and supervised, as mochi is a known choking risk.
The whole evening takes about twenty minutes and creates exactly the kind of memory kids carry around for decades: the parent in the silly mask, the shouting, the sweep-up afterward. Food is part of it, but the point is the doorway moment — out with the bad, in with the good.
Frequently Asked Questions
What is Setsubun and when is it celebrated?
Setsubun means the seasonal division, and today it refers to the day before risshun, the traditional start of spring on the old seasonal calendar. It usually falls on February 3, and occasionally on February 2. Families mark it at home with mamemaki, a bean-throwing ritual that chases out bad luck, then eat roasted soybeans and, in many homes, a thick sushi roll called ehomaki. It is not a public holiday, so it fits into an ordinary school evening.
What do people shout during mamemaki?
The classic call is Oni wa soto, fuku wa uchi, which means demons out, good fortune in. Someone, often a parent, wears a paper oni (demon or ogre) mask while the kids toss roasted soybeans toward the doorway or at the oni, then beans are scattered inside for good fortune. Wording and details vary by family, region, and temple, so there is no single correct version.
Can young children eat the roasted soybeans at Setsubun?
Not children age 5 and under. Whole roasted soybeans are small, hard, and round, which makes them a choking hazard, and dry bean fragments can also be inhaled into the airways. Japan's Consumer Affairs Agency advises not giving hard beans and nuts to young children, and the American Academy of Pediatrics lists whole nuts and similar hard, round foods as hazards for children under 4. Let little ones throw individually wrapped bean packets instead, and give them a soft soybean snack such as kinako on yogurt or mashed edamame to eat.
Why do people eat beans by age?
The custom is to eat one roasted soybean for each year of your age, and some families add one more for the year ahead, as a wish for good health through the coming year. For younger kids you can keep the counting ritual and swap the food: count out soft pieces, edamame that has been mashed or halved for small children, or a matching number of kinako-dusted bites.
What is ehomaki and how should kids eat it?
Ehomaki is a thick, uncut sushi roll eaten while facing that year's lucky direction, called eho. Many people eat it in silence, start to finish, as a wish for good fortune. The custom has roots in the Osaka area and spread nationwide in recent decades. For kids, it is completely fine to break the rule: slice the roll into thin rounds or make small, thin hand rolls, cut fillings into small pieces, and keep young children seated and supervised, since nori can be hard for them to bite through.
