Shikoku is the island of the eighty-eight temple pilgrimage, and Kagawa — old Sanuki province, its smallest corner — is where pilgrims and everyone else eat udon. Not occasionally: structurally. The prefecture has more udon shops per person than anywhere in Japan, schoolchildren tour noodle factories, and the local legend credits the dish to Kōbō Daishi himself, the Heian-era monk who carried Buddhism — and, Kagawa insists, noodle technique — home from China in 806.
What makes a bowl Sanuki is koshi: a dense, springy, alive chew that cheap udon doesn't have and can't fake. It comes from a hard, well-salted dough and an unhurried rest — nothing exotic, just discipline. The broth is the region speaking too: iriko dashi, built on dried sardines from the Seto Inland Sea, lighter in color and saltier in soul than Tokyo's.
The kake bowl here is udon at its most honest — noodles, hot broth, scallions, done. If your noodles have real koshi, you'll understand why Kagawa never felt the need to add much else.
Sanuki udon is judged by koshi — the live, springy resistance at the center of the noodle. Salt in the dough and a real rest are where koshi comes from. Skip neither.

Ingredients材料
Serves 4
Noodles
- 300 gall-purpose flour — or udon flour if you can get it
- 140 mlwater
- 15 gsalt
Iriko dashi & bowl
- 1 Lwater
- 25 giriko / niboshi (dried baby sardines) — heads and guts pinched off for a cleaner broth
- 8 gkombu
- 2.5 tbspusukuchi (light) soy sauce — regular soy works; the broth will just be darker than Kagawa likes
- 1 tbspmirin
- 2scallions, thinly sliced
- shichimi tōgarashi and tempura crumbs, at the table
Method作り方
Step 1: Make a stiff, salty dough
Dissolve the salt fully in the water, then work it into the flour. The dough will feel stubborn — that's correct. Knead 10 minutes (the Kagawa method is to bag it and tread it underfoot in clean socks, and we're not joking), then rest it, wrapped, 2 hours or overnight in the fridge.
Step 2: Steep the iriko dashi
Soak iriko and kombu in the water 30 minutes, warm slowly to just under a boil, pull the kombu, simmer the iriko 5 gentle minutes, and strain. Season with usukuchi soy and mirin. This sardine broth, not katsuobushi, is Kagawa's signature.
Step 3: Roll and cut
Roll the rested dough to 3 mm and cut into 3 mm noodles — square in cross-section, dusted well. Uniformity matters more than thinness; uneven noodles cook unevenly.
Step 4: Boil hard, wash hard
Boil in a large pot of unsalted water 8 to 10 minutes until just cooked through, then wash vigorously in cold water to strip surface starch and set the koshi.
Step 5: Assemble the kake bowl
Dip the noodles briefly in hot water to rewarm, bowl them, and ladle over the hot iriko broth. Scallions on top, shichimi and tempura crumbs to taste, and eat immediately — a Sanuki bowl waits for no one and never has.

Questions from the kitchen
Is udon really Heian-era?
The legend is: Kagawa says Kūkai (Kōbō Daishi), the Heian monk born there in 774, brought noodle-making home from Tang China. Historians argue over what that proto-noodle was; udon as we know it firms up centuries later. We tag the dish to its legend and tell you honestly that it is one.
Why is Kagawa so obsessed with udon?
Geography wrote the menu — Japan's smallest prefecture is dry and rice-poor but grows good wheat, harvests salt from the Inland Sea, and nets iriko off its coast. Flour, salt, sardine broth: the entire dish grows within sight of itself. Kagawa now eats more udon per capita than anywhere in Japan, by a scandalous margin.
Can I use frozen udon?
For weeknights, absolutely — frozen Sanuki-style udon is one of the best products in the freezer aisle, far better than dried. But make the dough by hand once. Koshi you have kneaded yourself recalibrates what you accept from a package.
