What Is Udon?
Udon (うどん) are thick, chewy wheat noodles served in a light dashi broth, and they rank among Japan’s most comforting everyday foods. Whether you’re grabbing a quick bowl at a self-service chain, sitting down at a regional specialty restaurant, or making udon at home, understanding the varieties and etiquette of udon dining will enrich your daily life as a resident in Japan.
Regional Udon Styles
Udon is deeply regional. The broth, noodle thickness, and toppings vary significantly by prefecture:
| Region | Style | Characteristics |
|---|---|---|
| Kagawa (Sanuki) | Sanuki udon | Japan’s most famous — very firm, chewy noodles. Light soy broth. Self-service common. |
| Osaka/Kyoto | Kansai udon | Soft noodles in a delicate, pale dashi broth. More subtle flavor. |
| Tokyo/Kanto | Kanto udon | Darker, soy-heavy broth. Noodle texture between Sanuki and Kansai. |
| Akita | Inaniwa udon | Very thin, flat, silky noodles. Often served cold with dipping sauce. |
| Gunma/Yamanashi | Hoto/Oshimugi | Flat, very thick noodles cooked in miso broth with vegetables. |

How to Order at a Udon Restaurant
Udon restaurants range from vending machine ticket systems to full table-service restaurants. Here’s how each works:
- 券売機 (kenbaiki) system: Buy a ticket from the vending machine at the entrance, hand it to staff. Common at budget chains like Marugame Seimen and Hanamaru Udon.
- Tray-line (self-service) system: Pick up a tray, order at the counter, add toppings yourself, pay at the end. Typical at Kagawa-style udon shops.
- Table service: Standard ordering via menu and waiter at sit-down establishments.
For cold or warm, you’ll often be asked: 冷たい/温かい (tsumetai / atatakai) — cold or hot. In summer, cold udon (ざる/ひや) is popular; in winter, hot broth is preferred.
Popular Udon Chains in Japan
- 丸亀製麺 (Marugame Seimen) — largest udon chain in Japan. Fresh noodles made in-store. Good value, nationwide coverage.
- はなまるうどん (Hanamaru Udon) — another nationwide chain with self-service toppings bar. Slightly cheaper than Marugame.
- 資さんうどん (Sukesanudon) — Fukuoka-based chain with richer broth and larger portions.
Eating Udon: Etiquette Notes
- Slurping is acceptable — in fact it’s normal and some argue it cools the noodle and enhances flavor.
- Drink the broth. Udon broth (especially light Kansai-style) is meant to be sipped. Use the spoon provided or lift the bowl.
- Order size options. Most chains offer 並 (nami, regular), 大 (dai, large), and sometimes 小 (shou, small) for the same price or small difference.
- Return your tray. At self-service chains, clear your own tray before leaving.
Making Udon at Home
Udon noodles are widely available at Japanese supermarkets. Look for:
- 冷凍うどん (frozen udon) — highest quality for home cooking. Tablemark and other brands sell individually portioned frozen udon that cooks in 60 seconds in boiling water or microwave.
- ゆでうどん (boiled udon) — pre-cooked vacuum-packed noodles. Convenient but softer texture.
- 乾麺うどん (dried udon) — needs 10-15 minutes to cook. Good texture when done right.
For the broth, buy だしパック (dashi packs) or めんつゆ (mentsuyu) — a concentrated dashi-soy sauce base available at all supermarkets. Dilute mentsuyu 1:3 with water for a quick udon soup.
