Regional styles, top restaurants, wanko soba, Sanuki udon pilgrimage & how to slurp like a local
Japan's noodle culture runs far deeper than ramen. Udon and soba each have centuries of regional tradition — from Kagawa's legendary Sanuki udon (where locals eat noodles for breakfast at ¥350 a bowl) to Morioka's all-you-can-eat wanko soba ritual, to hand-ground mountain soba in the cedar forests of Togakushi. This guide covers where to eat, what to order, and the stories behind Japan's most loved noodle styles.

Specialty: Regional Udon Destination
Hours: Most shops open 7:00 AM – 3:00 PM; sell out early
Price: ¥300–¥700 per bowl (toppings extra)
Kagawa, the smallest prefecture in Japan, is the undisputed homeland of Sanuki udon — a style defined by extremely firm, chewy noodles in a clear iriko (dried sardine) dashi with a touch of sweet soy. The prefecture has over 800 udon restaurants. Top shops include Yamashita Udon (thick noodles, house tempura), Udon Baka Ichidai in Marugame (famous queues), and Kanakoya near Takamatsu Station. Morning visits are essential — many shops close by noon.
Tip: Pick up the Kagawa Udon Passport at tourist offices (¥1,400 for discounts at 70+ shops). Start early — 8 AM opening at popular shops means the best noodles before 10 AM. Rent a bicycle from JR Takamatsu Station for the self-guided Udon Pilgrimage route.
Specialty: Wanko Soba Restaurant
Hours: 11:00 AM – 8:30 PM (last order 8:00 PM); closed Tuesdays
Price: ¥2,750 (regular); ¥3,850 (premium with extra toppings)
One of Morioka's most established wanko soba restaurants, running the all-you-can-eat refill tradition since 1907. Small lacquer bowls of hot soba arrive in a rapid rhythm — an attendant flips the lid closed when you signal stop. Included toppings: salmon, ikura, natto, tuna, grated yam, pickles, and sesame. English menus and photo boards available. Most visitors eat 30–60 bowls; competitive eaters attempt 100+.
Tip: Wear loose clothing — you will eat significantly more than you expect. Give a clear 'OK' signal with both hands when you've had enough, or the attendant keeps coming. Arrive at 11 AM opening to avoid 45-minute waits on weekends.
Specialty: High-End Soba Restaurant
Hours: 11:30 AM – 3:00 PM, 5:30 PM – 10:00 PM; closed Tuesdays
Price: Soba ¥1,400–¥2,800; dinner courses from ¥5,000
A beloved Tokyo soba institution with over 40 years of history. Honmura-an grinds its own buckwheat in-house daily, producing noodles with pronounced earthy flavour and a firm bite. The cold zaru soba (¥1,650) on a bamboo mat with house tsuyu is the benchmark. Duck-based hot soba (kamo namban) is exceptional in winter. The Roppongi location occupies a traditional townhouse with a small Japanese garden.
Tip: Order the tasting set at lunch (soba + tempura + mini rice, ~¥2,500) for the best value. Reserve in advance for dinner — the restaurant seats only 30 and fills up. Soba made fresh daily means quality peaks before 2 PM.
Specialty: Regional Udon Restaurant
Hours: 11:00 AM – 3:00 PM, 5:30 PM – 10:00 PM
Price: ¥800–¥1,500 per bowl
A Tokyo representative of Hakata-style udon from Fukuoka — softer and silkier than Sanuki, with a delicate chicken and kelp broth. The house topping is a thick slab of burdock tempura (goboten) that slowly softens into the soup. A rare chance to taste Kyushu's gentler udon tradition without travelling to Fukuoka. Located in Shimokitazawa, popular with locals.
Tip: The weekday lunch set (udon + rice + pickles, ¥1,200) is excellent value. Try the cold kamaage udon in summer — noodles served straight from the pot in a bowl of hot starchy cooking water, dipped into concentrated tsuyu.
Specialty: Osaka Udon Restaurant
Hours: 11:00 AM – 10:00 PM daily
Price: ¥850–¥1,500
Osaka udon is typically softer than Sanuki and served in a lighter, more savoury dashi. Menba Taketora in Namba is known for its deeply flavoured house broth and generous toppings — particularly the kitsune udon (sweet aburaage fried tofu on top, a classic Osaka dish) and the curry udon with its rich, spiced sauce. Popular with locals and tourists alike, a 5-minute walk from Dotonbori.
Tip: The classic Osaka order: kitsune udon (¥850) + a side of rice and pickled plum (¥200). Osaka kitsune udon uses sweeter aburaage than Kyoto's version — ask staff to explain the difference if interested. Namba is a great area to combine with okonomiyaki and takoyaki for a full Osaka food tour.
Specialty: Regional Soba Destination
Hours: Restaurants open 11:00 AM – 3:00 PM (closing varies)
Price: ¥1,200–¥2,500 per set
Togakushi, in the mountains north of Nagano City, is home to one of Japan's most celebrated regional soba styles — thin, square-cut noodles made with a high ratio of local mountain buckwheat and served cold on lacquered trays. The village of Togakushi Chushamichi has a cluster of soba restaurants that have operated for generations. Surrounded by cedar forests and the approach to Togakushi Grand Shrine, the setting enhances the meal.
Tip: Combine with a visit to Togakushi Ninja Village (Togakure-ryu Ninjutsu Museum) 5 minutes from the soba street — the birthplace of one of Japan's oldest ninja schools. 40 minutes by bus from Nagano Station (¥1,500). Best in autumn (October) when maples line the shrine approach.
Choose udon if you prefer: mild, comforting flavour; soft and filling; cold or hot equally good; more topping variety; budget-friendly options. Choose soba if you prefer: complex, earthy buckwheat taste; cold dipping style (zaru soba); lighter calorie count; a more traditionally Japanese dining ritual. In western Japan (Osaka, Kagawa), udon reigns; in Tokyo and the northeast, soba is king.
Japan's main udon regional styles: Sanuki (Kagawa) — firm, chewy, iriko dashi; Inaniwa (Akita) — thin, silky dried udon; Kishimen (Nagoya) — flat, ribbon-shaped noodles in a dark soy broth; Misonikomi (Nagoya) — simmered in red miso broth; Hakata (Fukuoka) — soft, round noodles in chicken broth; Himokawa (Gunma) — extremely wide, flat noodles. Each style reflects local water quality and agricultural traditions.
Japan's celebrated soba regions: Togakushi (Nagano) — thin, square-cut, high-buckwheat ratio; Wanko Soba (Iwate) — all-you-can-eat refill tradition; Izumo Soba (Shimane) — dark buckwheat, served in stacked lacquer bowls; Shinshu Soba (Nagano general) — strong mineral water, firm texture; Edo Soba (Tokyo) — thinner, urban style, often served cold. Noodles aged overnight taste different from fresh-milled morning soba — both styles have advocates.
Most udon and soba shops use a ticket machine (vending machine) at the entrance — insert coins or cash, press your choice, receive a ticket, hand it to staff. Useful terms: kake (hot broth), zaru/mori (cold with dipping sauce), tempura (with tempura), niku (with meat), tsuke-men style (noodles and broth separate). If no ticket machine, say "kore o kudasai" and point to the menu. Hot or cold: atsui/tsumetai.
Freshly made soba and udon have a noticeably different texture and flavour from pre-cooked noodles. Peak quality is in the first hours after a shop opens — typically 11 AM–1 PM. Many soba restaurants make only a limited batch daily and close once sold out (usually by 2–3 PM). If a shop has a handwritten sign reading "sold out" (完売/SOLD OUT), it's actually a quality signal — return the next morning before noon.
Soba noodles are naturally gluten-reduced (depending on buckwheat ratio) and lower glycaemic than wheat noodles — though not gluten-free due to wheat binders. Both udon and soba provide significant protein from broth dashi. Watch for hidden allergens: tempura batter contains eggs and wheat; mirin (sweet rice wine) is in most tsuyu; some broths contain pork. Many shops now have English allergen charts — ask at the counter.

Udon are thick, chewy white noodles made from wheat flour — mild in flavour with a soft, bouncy texture. Soba are thin, earthy brownish noodles made from buckwheat flour (typically 30–80% buckwheat, the rest wheat) — with a nuttier, more complex taste. Udon tends to absorb the broth more; soba is often eaten cold with a dipping sauce (zaru soba) in summer. Udon is more popular in western Japan (Osaka, Kagawa); soba is stronger in Tokyo, Nagano, and the northeast.
Sanuki udon (from Kagawa Prefecture, formerly called Sanuki Province) is Japan's most celebrated udon style — incredibly chewy, firm noodles in a light, sweet dashi broth made with iriko (dried sardines). Kagawa has more udon restaurants per capita than anywhere on Earth. Top spots: Yamashita Udon (Takamatsu), Udon Baka Ichidai (Marugame), and Kanakoya (Takamatsu). Budget ¥300–¥700 per bowl. Consider the Kagawa Udon Pilgrimage — a self-guided tour of 88 top udon shops.
Wanko soba is an all-you-can-eat soba tradition from Iwate Prefecture (northeastern Japan), specifically Morioka and Hanamaki cities. Small lacquer bowls of soba are refilled by an attendant who flips the lid closed when you've had enough. The record is over 500 bowls. Top restaurants: Azumaya (Morioka), Hanamaki Wanko Soba Kan. Expect to eat 30–60 bowls in a typical sitting (about 1.5–2 portions of regular soba). Cost: ¥2,500–¥3,500 all-inclusive.
Yes — slurping is not only acceptable but considered a compliment to the chef in Japan. It aerates the noodles, enhances flavour, and cools them before they reach your mouth. Loud slurping at ramen, udon, and soba shops is completely normal. What is rude: talking with your mouth full, blowing on food to cool it (considered childish), and passing food chopstick-to-chopstick (a funeral rite association).
For udon: tempura (kakiage mixed vegetable tempura is classic), a soft-boiled egg (onsen tamago), aburaage (fried tofu, especially in Kyoto kitsune udon), and raw egg (tamago udon in Kagawa). For soba: tororo (grated mountain yam), duck (kamo), fresh wasabi (horseradish), and natto (fermented soybean — polarising but popular). Cold zaru soba comes with only nori strips and a dipping tsuyu — add wasabi and spring onion to the dipping sauce.
Udon and soba noodles themselves are vegan, but most broths contain dashi made from katsuobushi (dried bonito fish flakes) or niboshi (dried sardines). Vegetarian-friendly options exist but require asking. In Kyoto, some traditional restaurants use kombu (kelp) dashi. Major cities (Tokyo, Osaka, Kyoto) have specialist vegan Japanese noodle restaurants. The phrase to use: "Dashi wa kombu dake desu ka?" (Is the dashi only kelp?). Tempura toppings typically use eggs in the batter.
