Japan Through Food

How a simple dish called dengaku evolved from popular street food into one of Japan’s favorite winter meals.

What Is Oden?

Walk through Japan on a cold winter evening, and you may encounter a familiar smell drifting from a restaurant, an izakaya, or even a convenience store.

Inside a steaming pot, daikon radish, eggs, konnyaku, fish cakes, and other ingredients slowly simmer in a savory broth.

This is oden, one of Japan’s classic winter comfort foods.

Today, oden seems inseparable from broth. The ingredients absorb the flavor of dashi as they simmer together, creating a dish that is warm, simple, and deeply comforting.

But oden did not begin this way.

In fact, if you traveled back several centuries, you might not even recognize it.

The ancestor of modern oden was not simmered in broth.

It was tofu grilled on a stick.

Oden Began with Dengaku

The roots of oden are generally traced to tofu dengaku.

Tofu was cut into pieces, placed on skewers, grilled, and eventually served with miso.

The name dengaku itself has an interesting story.

Originally, dengaku referred to traditional performances associated with rice planting. One explanation holds that the appearance of tofu on a skewer resembled performers in dengaku dances. The food therefore came to be known by the same name.

Over time, dengaku was shortened in courtly women’s language: an honorific o was added, and the latter part of the word was dropped.

Dengaku became o-den.

Yet the food behind that name would change dramatically.

Oden Becomes Food for the People

By the Edo period, dengaku had become a popular everyday food.

Tofu and konnyaku were skewered, seasoned with miso, and sold to ordinary people. Historical sources and images from the period show oden being sold by street vendors.

In modern terms, we might think of it as a kind of Japanese fast food.

It was inexpensive, convenient, and available to people living in a rapidly growing city.

That matters because Edo—modern-day Tokyo—was becoming one of the world’s great urban centers.

People needed food that could be prepared, sold, and eaten conveniently.

Long before convenience stores and takeout apps, street vendors were already feeding the city.

Oden belonged to that world.

But When Did Oden Become a Stew?

This is where the history becomes more complicated.

There is no single moment when grilled dengaku suddenly turned into the oden we know today.

Different forms developed over time, and accounts of exactly when modern simmered oden emerged vary.

What we can say is that simmered oden became increasingly established in the modern period.

By the Meiji era, oden with more ingredients and plenty of broth was becoming popular. As it spread beyond Tokyo, different regions adapted the dish to local tastes and ingredients.

The transformation was remarkable.

A piece of tofu on a stick had become a pot filled with different ingredients simmering together.

And oden was still changing.

From the Street to the Japanese Home

For a long time, oden was strongly associated with street stalls and specialist restaurants.

Then, particularly after World War II, fish cakes and other prepared ingredients became easier for ordinary households to buy.

Oden gradually became a familiar home-cooked meal.

That changed what oden meant.

It was no longer simply something bought outside.

A large pot could be placed in the middle of the family table.

One person might prefer daikon.

Another might reach for an egg.

Someone else might choose konnyaku or a favorite fish cake.

And because the ingredients simmer together in the same broth, each contributes something to the flavor of the whole pot.

In this way, a dish that once belonged to the streets became part of everyday family life.

There Is No Single Oden

Perhaps the most fascinating thing about oden today is that there is no single recipe that defines it.

Travel around Japan and the dish changes.

In Tokyo, ingredients such as chikuwabu and hanpen are common.

Shizuoka is known for dark broth and black hanpen.

Around Himeji, oden may be eaten with ginger soy sauce.

In parts of Kyushu, chicken-based broth and sweeter soy sauce are characteristic.

Other regions add seafood, local vegetables, miso, or distinctive sauces.

So a bowl of oden can tell you something about where in Japan you are.

The same dish becomes a map of regional food culture.

A Dish That Has Never Stopped Changing

Oden is sometimes described simply as a Japanese stew.

That is not wrong.

But it misses the most interesting part of the story.

Oden has been changing for centuries.

Grilled tofu became popular street food.
Street food became simmered oden.
Oden spread across Japan.
Regional versions developed.
And a dish once eaten outside became a familiar meal at home.

Today, you can still find oden in restaurants and izakaya, prepare it at home, and encounter ready-to-eat versions that make the dish easier to enjoy.

The form changes.

The way people eat it changes.

But the dish continues.

Perhaps that is one reason oden tells us something interesting about Japanese food culture.

Tradition does not always mean preserving something exactly as it was.

Sometimes, tradition survives because it changes.

And the next time you look into a steaming pot of oden, you may be looking at the latest chapter of a story that began with a simple piece of tofu on a stick.
