When the hot, humid days of Japanese summer finally give way to the crisp, clear air of autumn, something magical happens. The air feels lighter, the skies bluer, and the countryside bursts into vibrant shades of red, orange, and yellow. But perhaps the most cherished part of autumn in Japan is not just the scenery — it’s the food.
Autumn in Japan is often referred to as “shokuyoku no aki” (食欲の秋), which translates to “the season of hearty appetites.” After enduring summer heat that can suppress hunger, autumn is a time when people naturally feel hungrier — and nature provides the perfect bounty to satisfy that craving. The autumn harvest is central to Japanese culture, traditions, and celebrations, with seasonal flavors like chestnuts, sweet potatoes, and mushrooms taking the spotlight.
Let’s explore how food shapes this season in Japan and why these autumn harvest traditions are so beloved.
The Cultural Importance of Autumn Food
In Japanese culture, eating seasonal food — “shun” (旬) — is considered the best way to live in harmony with nature. Each season brings different ingredients at their peak of freshness and flavor, and autumn is perhaps the richest of all. Historically, autumn was also the time of rice harvesting, making it a season of abundance and gratitude.
Many Japanese festivals and traditions revolve around celebrating the harvest, giving thanks for the food provided, and enjoying the unique tastes of this time of year. Whether through traditional festivals, family meals, or limited-edition snacks sold in convenience stores, food is the heartbeat of autumn in Japan.
Chestnuts (Kuri): A Symbol of Autumn
Few foods say “autumn in Japan” as strongly as the humble chestnut, or kuri. Chestnuts have been eaten in Japan for thousands of years — in fact, archaeologists have found evidence that chestnuts were cultivated during the Jomon period, more than 3,000 years ago.
In autumn, chestnuts appear in both sweet and savory dishes. One popular way to enjoy them is kuri gohan (chestnut rice), where peeled chestnuts are cooked with rice and seasoned with a hint of salt. The subtle sweetness of the chestnuts pairs beautifully with the fluffy rice, making it a comforting dish enjoyed at home and in school lunch menus.
On the sweet side, chestnuts are turned into kuri manju (sweet chestnut-filled buns), mont blanc cakes, and even chestnut-flavored KitKats. In department store food halls, you’ll often see vendors roasting chestnuts and filling the air with their warm, nutty aroma — a smell that signals the heart of autumn has arrived.
Sweet Potatoes (Satsumaimo): The Cozy Comfort Food
Another iconic taste of Japanese autumn is the sweet potato, or satsumaimo. Unlike their American cousins, Japanese sweet potatoes are denser and sweeter, with a rich, almost honey-like flavor when roasted.
Perhaps the most nostalgic autumn food in Japan is yaki-imo (roasted sweet potato). During the cooler months, small trucks equipped with stone ovens drive through neighborhoods, calling out “yaki-imo, yaki-imo!” through loudspeakers. The roasted potatoes are sold piping hot, their skins slightly charred and their insides creamy and sweet. Holding a warm roasted potato on a crisp autumn evening is a memory many Japanese people treasure from childhood.
Sweet potatoes are also used in tempura, stews, and sweets like daigaku imo (candied sweet potatoes), which are glazed in a sticky-sweet syrup. They even appear in seasonal snacks — sweet potato-flavored chips, candies, and chocolates are supermarket staples throughout the fall.
Mushrooms (Kinoko): The Earthy Taste of Autumn
If chestnuts are the sweetness of autumn and sweet potatoes are the comfort, then mushrooms represent its earthy depth. Japan is home to a variety of edible mushrooms, and autumn is when they’re at their best.
The most famous is matsutake, a rare and highly prized mushroom with a unique spicy, pine-like aroma. Because they are difficult to cultivate and often harvested wild, matsutake can be incredibly expensive — sometimes selling for hundreds of dollars per kilogram. For those lucky enough to try them, matsutake are often grilled simply or served in dobin mushi, a delicate broth steamed in a teapot.
Other mushrooms, like shiitake, shimeji, and enoki, are more affordable and widely enjoyed. These varieties appear in everything from hot pots to stir-fries, offering earthy flavors that perfectly complement the cooling weather. Seasonal mushroom rice, kinoko gohan, is another autumn staple, often mixed with soy sauce and dashi for a savory, satisfying meal.
Seasonal Fruits and Other Harvest Treasures
While chestnuts, sweet potatoes, and mushrooms are the stars, autumn in Japan also brings a bounty of fruits and other seasonal delights.
-
Persimmons (kaki): Sweet, orange fruits that can be eaten fresh or dried into chewy hoshigaki. Persimmons are so strongly tied to autumn that they often appear in seasonal poems and artwork.
-
Apples: Especially from Aomori Prefecture, known across Japan for producing crisp, juicy apples that rival any in the world.
-
Pumpkins (kabocha): Used in stews, soups, and even sweets like pumpkin pudding, adding a gentle sweetness to autumn dishes.
-
Rice: The autumn rice harvest is one of the most important events of the year. Freshly harvested rice, called shinmai, is prized for its soft, glossy texture and rich flavor.
Each of these foods is celebrated not just for taste but for their connection to tradition, family meals, and the rhythm of the seasons.
Celebrating Autumn Through Festivals and Food
Many Japanese festivals in autumn are linked to harvest traditions. One of the most famous is Tsukimi (moon-viewing), where families admire the harvest moon while eating tsukimi dango (round rice dumplings). In rural areas, harvest festivals often feature offerings of rice, fruits, and vegetables to thank the gods for abundance.
Even in modern Japan, autumn foods are deeply woven into seasonal life. Convenience stores release special autumn flavors of snacks and drinks, restaurants highlight seasonal menus, and families gather to enjoy dishes that showcase the best of the harvest.
Why Autumn Food Matters
Food in Japan is never just about taste — it’s about connection. Eating seasonal foods is a way to feel in tune with nature, to celebrate traditions, and to share meaningful moments with family and friends. Autumn foods, in particular, represent comfort, warmth, and gratitude for abundance after the heat of summer.
Chestnuts, sweet potatoes, mushrooms, and persimmons aren’t just ingredients — they’re reminders of cozy evenings, festive gatherings, and the beauty of living with the seasons.
