Asahikawa shoyu ramen: a bowl with its own lid of lard

Here's something to notice the next time a bowl of Asahikawa ramen lands in front of you: look for the steam. Often there's surprisingly little, even though the soup underneath is scalding. The reason is a thin, glossy layer of lard across the surface, sealing in the heat like a lid. Take your first sip carelessly and you'll learn that lesson quickly.

That layer isn't decoration. It's a sensible answer to a very cold place.

Built for the cold

Asahikawa sits in the middle of Hokkaido, in a basin ringed by mountains, and its winters are fierce. It is well known as one of the coldest cities in Japan, and it holds the country's official record for the lowest temperature, set in the early twentieth century. When the air outside is that cold, a bowl that cools in minutes is a bowl wasted.

Lard solves the problem. Spread across the top of the soup, it slows the loss of heat, so the last sip is nearly as hot as the first. It also adds a gentle richness and a silky feel on the lips, without making the broth itself heavy.

The city is known for its zoo, a popular stop on Hokkaido itineraries, and as a gateway to the mountains of Daisetsuzan. But I'd argue that the soy-seasoned bowl is reason enough to stop.

Within Hokkaido, Asahikawa's ramen is often grouped with Sapporo miso and Hakodate shio as the island's three classic styles, one for each of the main seasonings. Asahikawa is the soy sauce corner of that triangle.

The double soup

Shoyu (醤油) ramen is seasoned with soy sauce, and Asahikawa's tends to be dark and savoury. What makes it interesting is the stock. Many shops use what's known as a double soup (ダブルスープ): a stock made from pork or chicken bones, combined with a second stock made from seafood, often dried fish.

Each half does a different job. The meat stock gives body and a deep, rounded flavour. The seafood stock adds a smoky, briny savouriness that lifts everything above it. Blended and seasoned with soy, the result is layered rather than loud: you taste the meat first, then a lingering, faintly oceanic finish.

I think this is one of the smartest ideas in regional ramen. Japanese cooking has long understood that savoury flavours from the land and the sea reinforce each other, the same principle that makes dashi so satisfying. Asahikawa applies it to a bowl that also has to survive a Hokkaido winter.

Firm noodles for a hot soup

The noodles are the other half of the story. Asahikawa ramen usually uses low-water noodles, meaning the dough contains comparatively little water. Noodles made this way have a firm, snappy bite, and they're often fairly thin and a little wavy.

They also absorb soup readily, which is a large part of their charm: as you eat, they take on more and more of the double soup's flavour. The trade-off is that they keep drinking up broth as they sit, so they're at their best eaten promptly. For more on how water and alkaline salts shape a noodle, see our guide to kansui and ramen noodles.

Toppings are classic and unfussy: chashu (チャーシュー, braised pork), menma (メンマ, seasoned bamboo shoots), chopped green onion and sometimes a sheet of nori.

How to eat it

• Respect the heat. The lard means the soup is hotter than it looks. Blow on the first spoonful, then blow on it again.
• Get to the noodles early. Low-water noodles keep absorbing broth, so they're at their best in the first few minutes.
• Taste the layers. Halfway through, sip the soup on its own and see whether you can pick out the meat and the seafood separately.
• Leave the fat alone. It might be tempting to push it aside, but the lard is part of the design, not an excess.
• Go in winter if you can. I think this is a bowl that makes the most sense when it's bitterly cold outside and you've just come in from the snow.

Warmth as a design brief

Most regional ramen styles grew from what was available nearby: local pork, local seafood, local soy. Asahikawa's grew from what the weather demanded, too. The double soup gives it depth, the noodles give it bite, and the lard gives it time, which might be the most precious ingredient of all on a winter night in central Hokkaido.

I like a bowl that knows exactly what it's for. Asahikawa's is for keeping you warm, from the first sip to the last, and it does that job beautifully.
