Kankan zushi (カンカンずし)

2026年6月17日

Kagawa is famous for udon, yet its food story runs deeper. One old dish carries a strange, catchy name. People call it Kankan zushi, a pressed sushi from Kagawa. Some also write it as Kankan sushi in English. The name comes from a sound, not a fish. Cooks once hammered wooden wedges to press it. That work made a steady “kan-kan” beat. So the dish earned its lively title. Kankan zushi カンカンずし Kagawa local sushi remains a regional treasure. Let me introduce this bold, blocky Kankan sushi.

What Is Kankan Zushi?

So what is Kankan zushi exactly? It is a traditional pressed sushi from Kagawa Prefecture. The dish belongs to the oshizushi, or pressed sushi, family. It uses sawara, known in English as Spanish mackerel. Cooks marinate the fish, then layer it with lightly vinegared rice. They press everything into a large wooden frame. So the result is a firm, dense block of sushi. In short, this is sawara pressed sushi, or さわらの押し寿司.

The Kabe district shaped this local style first. Kabe sits in old Shido, now part of Sanuki City. From there the dish spread across Sanuki City and into part of old Tsuda. So it counts as traditional sushi from the Higashi-Sanuki region in Kagawa. Locals also call it Horaita-zushi or kata-zushi. In Shido, some even say hako-zushi, meaning box sushi. Each name points to the same hearty, block-style sushi. This Sanuki Kankan zushi pressed sushi feeds a crowd with ease.

The Taste and Texture of Kankan Zushi

What does Kankan zushi taste like? The flavor leans salty, tangy, and deeply savory. Vinegar and salt cure the sawara, which sharpens its richness. The rice stays lightly vinegared, so it balances the fish. Honestly, the first bite tastes bolder than modern sushi. Here is what defines a good block:

A salty and vinegared sawara pressed sushi
Lightly vinegared rice and marinated Spanish mackerel
Firm, compact sushi blocks made to be portable
A large block-style pressed sushi from Kagawa
Layers scented with sansho or haran leaves
A clean aroma from Seto Inland Sea sawara (鰆)

The texture often surprises newcomers. Pressing makes each slice firm and solid. So the sushi holds together, even after rough handling. That sturdiness was the whole point, as we will see.

How to Make Kankan Sushi from Kagawa

So how do you make Kankan sushi from Kagawa? The method feels almost like carpentry. Each step rewards patience and a steady hand.

The Wedge-and-Mallet Method

First, cooks fillet the sawara and cure it in salt and vinegar. They press the cure until the flesh turns white inside. Next, they pack about a shō of vinegared rice into a wooden box. Then they lay the fish on top. Sansho or haran leaves go between the layers. Cooks often stack several boxes for a large batch. Finally, they fit a lid and drive in wooden wedges. A mallet taps those wedges, and a weight presses the block. So this wooden box pressed sushi uses wedges and a mallet. In effect, the maker presses by hammering wooden wedges into a frame.

The frame matters too. Old families used hard, odorless sendan wood. Most modern makers now choose cedar or cypress. After pressing, the sushi rests overnight to settle. The next day, cooks slice the firm block into portions.

Why It Is Called Kankan Zushi

So where does the odd name come from? Listen to the kitchen, and you will hear it. The mallet strikes the wedges with a sharp “kan-kan” rhythm. So the dish is named after that “kan-kan” hammering sound. Locals simply borrowed the noise of pressing. It is a rare sushi named for a sound, not a fish.

Why It Is Also Called Horaita-zushi

The dish carries a second name with its own story. Pressing makes the block extremely firm and dense. In fact, you could toss a piece without it falling apart. That toughness inspired the name Horaita-zushi (ほらいた寿司). So Kankan sushi is also called Horaita-zushi or kata-zushi. Both names celebrate how tightly cooks press it.

The History of Kankan Zushi

An Edo-Period Preserved Food

Kankan zushi began as a clever way to keep food. The dish dates to the Edo period in the Sanuki region. Salt, vinegar, and hard pressing all slowed spoilage. So the sushi lasted about a week in winter. In summer, it still kept for two or three days. This made it a traditional preserved food from Kagawa. It also counts as Edo period preserved sushi from the Sanuki region. Stacked boxes let families prepare large amounts at once.

Food for Fields and Festivals

Farm life shaped the dish in clear ways. Sanuki farmers held a spring custom called haruio. Before the busy season, they bought a whole sawara. Then they cooked many sawara dishes and invited relatives. Kankan zushi joined that celebration too.

The dish also fed workers during hard labor. So it became a farmhouse pressed sushi for field workers. Long ago, landlords served it to their farmhands. They even tossed a block to those seated farthest away. The sushi held its shape, so nothing crumbled. People also made it as celebration food and festival sushi in Kagawa.

Part of a Seto Inland Sea Sushi Culture

Kankan zushi fits a wider coastal tradition. The Seto Inland Sea shaped much of Kagawa’s cooking. Its calm waters give sawara, sardines, and shellfish. So local cooks built a rich, sea-based sushi culture. This Seto Inland Sea coastal sushi culture in Kagawa runs deep. Within it, Kankan sushi stands as a proud local cuisine of the Sanuki region.
