Seasonal Japanese Dining: What to Eat and When in NYC

Walk into most American restaurants and the menu stays essentially the same whether it's January or July. Maybe there's a seasonal salad or a holiday special, but the core offering is fixed. Japanese cuisine operates on an entirely different philosophy — one that's been refined over centuries and remains one of the most beautiful ideas in the culinary world: shun (旬), the art of eating things at their peak seasonal moment.

What Is Shun?

Shun (旬) is a concept that goes beyond simple "farm-to-table" freshness. It's the belief that every ingredient has a perfect moment — a brief window when its flavor, texture, and nutritional value reach their absolute peak. A tomato in August is a fundamentally different ingredient than a tomato in February. Japanese cuisine builds its entire philosophy around respecting and celebrating those peak moments.

In practical terms, this means a great Japanese chef doesn't just serve what's available — they serve what's at its best right now. The fish that appears on the menu in January may be replaced by something different in April, not because the first fish is unavailable but because a better option has emerged. It's a constant conversation between the kitchen and the calendar.

This philosophy creates a dining experience that's inherently dynamic. Visit a truly seasonal Japanese restaurant four times a year and you'll have four meaningfully different meals. The flavors change, the presentations change, even the ceramics and garnishes shift to reflect the mood of the season. It's one of the reasons Japanese dining rewards repeat visits in a way that few other cuisines can match.

Winter: The Season of Richness

Winter (December through February) is arguably the most exciting season for Japanese seafood in New York. Cold ocean waters produce fish with higher fat content — the culinary equivalent of nature insulating itself against the cold — and that fat translates directly into richer, more flavorful sushi and sashimi.

Winter Stars

Buri (Yellowtail / Winter Yellowtail): The undisputed king of winter sushi. Wild Japanese yellowtail caught in cold waters develops a rich, buttery fat layer that makes it one of the most luxurious fish on any menu. The difference between winter buri and summer yellowtail is as dramatic as the difference between a ripe August peach and its pale January supermarket cousin.

Fugu (Blowfish): Rare in NYC but available at select restaurants. The thrill of fugu isn't just its delicate flavor — it's the knowledge that this fish requires licensed preparation due to its toxic organs. It's an experience that's as much about trust and tradition as it is about taste.

Hot Pot (Nabe): Winter is nabe season — communal hot pots filled with broth, vegetables, tofu, and proteins that bubble at the table. In an izakaya setting, sharing a hot pot on a freezing night is one of the most warming social experiences in Japanese cuisine.

Warm Sake: This is when warm sake truly shines. The combination of rich winter fish, bubbling hot pot, and a steaming cup of Junmai sake is one of the great seasonal pleasures of Japanese dining.

Spring: Delicacy and Renewal

Spring (March through May) brings a shift from winter's richness to lighter, more delicate flavors. It's the season of fresh beginnings in Japanese food culture, reflected in ingredients that are subtle, tender, and often green.

Spring Stars

Tai (Sea Bream): Called "the king of fish" in Japanese cuisine, tai peaks in spring — particularly around March and April. Its flavor is clean, sweet, and delicate, making it perfect for sashimi, sushi, or simply grilled with salt. In Japan, tai is the traditional fish of celebration, often served at weddings and New Year.

Takenoko (Bamboo Shoots): Fresh bamboo shoots are a spring delicacy that tastes nothing like the canned version most people know. Freshly harvested takenoko has a sweetness and crunch that's been compared to a cross between artichoke hearts and corn. Grilled, tempura-fried, or simmered in dashi — they're versatile and unmistakably spring.

Cherry Blossom Season: Sakura (cherry blossom) season inspires an entire category of spring dishes and drinks — from sakura mochi (cherry blossom rice cakes) to sakura-infused cocktails. Even if the blossoms aren't on the trees outside, your plate can capture the season's spirit.

Mountain Vegetables (Sansai): Foraged mountain vegetables — fiddlehead ferns, wild garlic, butterbur sprouts — represent the wild, untamed side of spring. They bring a slight bitterness and earthy complexity that balances the season's sweetness.

Summer: Bold and Refreshing

Summer (June through August) in Japanese cuisine is about contrast — bold flavors balanced by cooling techniques. It's the season of refreshing cold dishes, vibrant garnishes, and ingredients that cut through the heat.

Summer Stars

Uni (Sea Urchin): Summer uni is a revelation. While uni is available year-round, the summer harvest produces the sweetest, most briny-buttery specimens — especially from Hokkaido. Served as nigiri, in a bowl over rice (uni don), or simply on a spoon, peak-season uni is one of the most extraordinary flavors in the ocean.

Unagi (Freshwater Eel): In Japan, there's an entire tradition of eating unagi on the hottest day of summer — the Doyo no Ushi no Hi tradition — because its rich nutrients are believed to combat heat fatigue. Whether or not you buy the health claims, glazed and grilled unagi over rice (unadon) is one of the most satisfying summer dishes imaginable.

Cold Soba (Zaru Soba): Chilled buckwheat noodles served on a bamboo mat with dipping sauce. Simple, refreshing, and deeply satisfying on a sweltering day. The noodles should be firm and nutty; the dipping sauce (tsuyu) cold and concentrated.

Shiso and Myoga: Summer herbs that bring brightness and aroma to everything they touch. Shiso (perilla leaf) has a flavor somewhere between mint and basil; myoga (Japanese ginger) adds a sharp, refreshing bite. Both are essential summer garnishes.

Fall: Depth and Harvest

Fall (September through November) is perhaps the most poetic season in Japanese cuisine — a time of abundance, earthiness, and the bittersweet beauty of impermanence. The ingredients take on deeper, more complex flavors as nature prepares for winter.

Fall Stars

Sanma (Pacific Saury / Pike Mackerel): The quintessential fall fish. Sanma grilled over charcoal with just salt and a squeeze of sudachi citrus is one of the most iconic seasonal dishes in all of Japanese cuisine. The fish is small, rich, and slightly bitter — a flavor profile that perfectly captures autumn's character.

Matsutake Mushrooms: The most prized mushroom in Japanese cuisine, matsutake appears briefly in fall and commands extraordinary prices. Its aroma is unlike any other mushroom — piney, spicy, and intensely fragrant. Even a small amount added to a clear soup (matsutake dobin mushi) transforms the dish into something ethereal.

Kaki (Persimmon): Sweet, honeyed persimmons are the fall fruit of Japan. They appear in desserts, are dried into intensely sweet treats, and even find their way into savory preparations. Their sunset-orange color is as much a part of fall aesthetics as changing leaves.

New-Harvest Sake (Hiyaoroshi): Fall brings the release of hiyaoroshi — sake that was brewed in winter, pasteurized once in spring, then aged through summer and released in fall without a second pasteurization. The result is a sake with more rounded, mellow flavors that pair beautifully with fall's earthy ingredients.

How to Eat Seasonally in NYC

You don't need to be a Japanese food scholar to eat seasonally. Here's the simple version:

1. Ask your server. "What's in season right now?" is the single most valuable question you can ask at any Japanese restaurant. A good server will light up and guide you to the best the kitchen has to offer today — not just what's always on the menu.
2. Look for specials. Seasonal items often appear as daily or weekly specials rather than on the permanent menu. These are usually the chef's most inspired dishes — the ones they're most excited about cooking.
3. Trust the chef. If a sushi restaurant offers omakase (chef's choice), take it. Omakase is essentially the chef saying: "Let me show you what's at its absolute best right now." It's the purest expression of seasonal dining.
4. Visit regularly. The beauty of seasonal dining is that it changes. Coming back every month or two means a genuinely different experience each time. It's the best argument for having a "regular" Japanese restaurant.

At Showa Era Izakaya, we take seasonal dining seriously. Our menu has a permanent core — the classics that our regulars depend on — but it's framed by rotating seasonal items that reflect what's freshest and most exciting at the market right now. In winter, that means rich yellowtail and warming ramen variations. In summer, you'll see refreshing cold dishes and peak-season seafood. The menu is a living document, constantly evolving with the calendar.
