Japanese Seasonal Foods and Shun: What Is in Season, Month by Month

The core idea: every food has its own short wave

English uses season both for a quarter of the year and for the time a food is at its best. Japanese keeps them apart: kisetsu is a season of the year; shun is the peak of one ingredient, and each ingredient's shun starts and stops on its own schedule.

Picture each food as a wave on a calendar. It appears, swells, peaks and dies away, sometimes within six weeks, which is why the kanji for ten days fits: a shun is counted in weeks. A food at its peak is cheaper, better and needs little cooking, so shoppers watch the waves closely. You are at a supermarket with a friend who cooks.

Hashiri, sakari and nagori: the three stages of a wave

The wave has three named parts. Hashiri (走り) is literally running: the food that runs ahead of its season. It is scarce and expensive, bought for the thrill of the first taste. The first one you eat in a season is a hatsumono, and an old saying claims it adds seventy-five days to your life.

Sakari (盛り), also simply called shun, is the peak. It uses the kanji of moru, to heap up, as in ōmori, a large helping: shops pile the food high and prices fall. Nagori (名残) is the tail end. The word is usually traced to nami-nokori, the waves left after the wind drops, and it carries a note of farewell; nagori oshii means sad to part. You are at a fish shop in late August.

The food year at a glance

The wheel places sixteen classic foods at roughly the months they peak in central Japan. Each label marks the crest of a wave, and most foods are good for a month or so either side.

Notice that summer and winter lean on dishes rather than harvests: shaved ice for the heat, hot pot for the cold. That difference matters later, when we look at what does not fit the wave.

Spring and summer: from bamboo shoots to shaved ice

Spring opens bitter. Nanohana, the shoots and buds of the rape plant, arrive in February and March, dressed with mustard; that slight bitterness tastes of spring to many Japanese people. Sakura mochi, a pink rice cake wrapped in a salted cherry leaf, appears from late February. Takenoko, bamboo shoots, peak around April near Tokyo and are boiled with rice bran the day they are dug. Hatsugatsuo, the first bonito, follows in May.

Early summer brings green ume, steeped into umeshu in June, during tsuyu, the rainy season, written 梅雨, literally plum rain. High summer means watermelon, suika, and kakigōri, shaved ice, sold under a flag printed with 氷. Eel belongs here by custom rather than flavour. Friends and family are chatting about food.

Autumn and winter: from saury to snow crab

Autumn is the richest stretch. Sanma is written 秋刀魚, literally autumn sword fish, a fair description of the long silver fish grilled whole with salt in September and October. Catches have fallen sharply over the past decade, so prices swing from year to year. Chestnuts go into kuri gohan, matsutake command startling prices (most sold in Japan are imported), and persimmons ripen in October and November.

Winter is about warmth and fat. Nabe, hot pot, runs through the cold months, mikan are eaten by the boxful at the kotatsu, kanburi, winter yellowtail, is at its fattiest, and snow-crab fishing from Toyama westward opens on 6 November. Shoppers and a fishmonger are talking.

Beyond the basics: pairs that are easy to confuse

Several seasonal words come in pairs that look or sound alike. The bonito pair is the most useful: the same fish has two seasons, one heading north and one on its way back.

The shun and kisetsu gentei pair matters most day to day. A sakura latte in March is a product launch timed to the season: it borrows the mood of shun, but nobody harvested it.

Beyond the basics: where the wave does not fit

Eel is the famous exception. Doyō no ushi no hi is the day of the ox in the eighteen days before risshū, the start of autumn; in 2026 there is just one, on 26 July. Eel is eaten then for stamina, and an old custom recommends any food starting with u, such as udon. Wild eel is said to be best from late autumn to early winter.

Dishes follow the weather, not the harvest: nabe and kakigōri are seasonal but have no shun. Greenhouses blur things too: strawberries fill shops from December, yet in haiku they are an early summer word.

Region shifts every wave. Bamboo shoots appear in Kyushu weeks before Tokyo, saury is landed first off Hokkaido, and sakura mochi changes form: a thin rolled crepe, chōmeiji, around Tokyo, grainy steamed rice, dōmyōji, in Kansai. A visitor from Tokyo is talking with a host in Osaka.

At the counter and the market: how people really talk about shun

Shop staff call out in casual, clipped speech: yasui yo, it's cheap, and ima ga shun da yo. Customers answer politely or neutrally. At a sushi counter, listen for hairu, to come in: ii no ga haittemasu yo means some good ones have come in, with the i of imasu dropped.

Shun has spread beyond food: shun no wadai is a topical subject. You are at a sushi counter on a December evening.

Common mistakes with shun and seasonal food

Saying shun wa aki desu to mean it is autumn. English season covers both ideas; Japanese does not. Shun needs a food: kuri no shun wa aki desu. For the season itself, use kisetsu.

Reading 旬 as jun on its own. Learners meet it first in jōjun and gejun, the first and last ten days of a month, where it is read jun. Alone, and in shun no yasai, it is shun.

Using hashiri and nagori in casual chat. They are the words of chefs and menus, so in a supermarket they sound like a brochure. With friends, say dehajime and owarikake.

Treating one city's calendar as the country's. A Tokyo peak may come a month earlier in Kagoshima and later in Sapporo, and a poor year at sea moves everything. Ask kochira de wa itsu ga shun desu ka, and you get the answer plus a conversation.
