Udon in Japan: What Makes Sanuki Udon Different, and Where to Eat It
Kagawa Prefecture takes its udon seriously enough to be nicknamed Udon Prefecture. Here's what separates real Sanuki udon from the rest, and where to find it.
Kagawa Prefecture, the old Sanuki Province, is nicknamed "Udon Prefecture". Sanuki udon is thick and noticeably chewy, and most shops there are cheap and self-service, open from the morning until the noodles run out in the early afternoon.
How a self-service shop works
Take a tray, order your noodles (and say whether you want them hot or cold, and how many portions), pick tempura and toppings from the counter, then pay at the register. Some shops have you warm the noodles yourself in a basket.
Styles
- Kake: noodles in hot dashi broth.
- Bukkake: a little strong sauce poured over the noodles instead of a full broth.
- Kamaage: noodles straight from the pot, with dipping sauce on the side.
- Kamatama: straight from the pot, tossed with raw egg and soy sauce.
Where to eat in Kagawa
Chikusei (Takamatsu). A self-service shop known as the place that invented the hot soft-boiled egg tempura. Lunchtime only: 10:45–14:30, closed Sundays and Mondays. 2-23 Kameoka-cho, Takamatsu · 087-834-7296
Ueharaya Honten (Takamatsu). Self-service, across from Ritsurin Garden, so it's easy to pair with a visit. 9:30–15:30, closed Sundays. 1-18-8 Ritsurin-cho, Takamatsu · 087-831-6779
Yamagoe Udon (Ayagawa). Open since 1941 and the birthplace of kamatama udon; the story goes that a regular brought his own egg. You'll need a car or taxi. 9:00–13:30, closed Sundays and Wednesdays. Expect a queue.
Gamo Udon (Sakaide). A small rural shop many udon fans treat as a must-visit. 8:30–13:30, closed Sundays and Mondays. Car recommended.
Takamatsu is also where ferries leave for Naoshima, so an udon morning fits well with an art island day.
Outside Kagawa: Marugame Seimen
The largest udon chain in Japan is named after Marugame in Kagawa but was founded in Kakogawa, Hyogo, in 2000. Noodles are made and boiled in front of you, and there's one in most cities, which makes it the easiest way to try Sanuki-style udon without going to Kagawa.
FAQ
What is Sanuki udon? The regional udon style from Kagawa Prefecture (historically Sanuki Province), known for a distinctly chewy, springy noodle texture from a specific kneading and resting process.
Why is Kagawa called "Udon Prefecture"? Because of its unusually high concentration of dedicated udon shops relative to its population, and the strong regional identity built around Sanuki-style udon specifically.
Is Marugame Seimen from Kagawa? No — despite being named after Marugame, a city closely associated with Sanuki udon, the chain was actually founded in Kakogawa, Hyogo Prefecture, in 2000.
What's the difference between kake udon and bukkake udon? Kake udon is served in a full bowl of hot broth; bukkake udon is topped with a smaller amount of concentrated cold sauce, putting more focus on the noodle texture itself.
Can I combine an udon trip with a Naoshima visit? Yes — Takamatsu, Kagawa's prefectural capital and a strong udon destination in its own right, is also one of the two main ferry departure points for Naoshima.
What are the best-known udon shops in Kagawa? Chikusei and Ueharaya Honten in Takamatsu are the easiest to reach without a car. Yamagoe Udon (Ayagawa), credited as the birthplace of kamatama udon, and Gamo Udon (Sakaide) are the more serious pilgrimage stops — both require a car or taxi and are worth the trip if you want the noodle at its source rather than the tourist-convenient version.
