Background
Sanuki udon is the udon of Kagawa Prefecture (formerly Sanuki Province), famed for its thick, chewy noodles. According to Japanese Wikipedia, Sanuki has long hours of sunshine and plenty of flat land suited to grain; from the Sengoku to the Edo period double cropping flourished and wheat production increased, and the landscape of irrigation ponds dotting the Sanuki Plain also took shape at that time. On the Konpira Festival Folding Screen from the end of the Genroku era (early 18th century), three udon shops can already be seen in the approach town of Kotohira-gu; in the late Edo period, many inns serving Konpira pilgrims ran udon shops on their ground floors. Salt, sugar and cotton were called the "three whites of Sanuki," and together with soy sauce from Shodoshima and dried small fish from the Seto Inland Sea, they provided the conditions for udon. Today Kagawa has a great many udon shops, and the self-service (serufu) shops and small shops run directly by noodle makers are the most distinctive.
Local customs
- At self-service shops the routine is usually: take a tray and order noodles (choosing size, hot or cold), add tempura and other sides yourself, pay at the register, add green onion and ginger yourself, and return your dishes to the return station when done
- common styles include kamaage, bukkake, kake and shoyu udon.
Religion & beliefs
- Sanuki udon has historical ties to the pilgrimage culture of Kotohira-gu (Konpira)
- in the Edo period, pilgrims ate udon along the way in the shrine's approach town. A local tale says Kukai brought udon to the area, but this is legend. Kukai was an eminent monk from Sanuki, several of the 88 temples of the Shikoku pilgrimage are in Kagawa, and pilgrims also often eat udon on the way.

Japan: At fireworks festivals, don't tape off spots in advance, and never fly drones
Do
- Spread your sheet where there is actual space when you arrive, leaving room for neighbours
- Follow police and staff directions and move with the crowd
- Bring plenty of water and cooling gear to prevent heatstroke
- Riverbanks have lots of insects, so bring repellent
- Festivals usually go ahead in light rain, so bring a raincoat
- Take your rubbish home
Don’t
- Don't mark spots in advance with tape or spray paint on roads or in parks
- Don't fly drones
- Don't use selfie sticks in crowds; the Sumida River festival bans them
- Don't stop in the middle of the path to watch and block the flow
Spots marked in advance are cleared by the organisers, and flying drones is prohibited by law. City-centre festivals run one-way crowd flows, and going against the flow or stopping can cause dangerous crushes.

Mixed, open-air and private baths: read the signs, don't stare, never take photos
Do
- Check the signs before entering; mixed baths are clearly marked, and joining is entirely your choice
- Most mixed baths are nude only, with no swimwear; some allow or lend special bathing wraps or towels, so follow the bath's rules
- If you prefer not to bathe mixed, use the separate men's and women's baths or a private bath
- Outdoor baths are slippery and the temperature changes sharply; hold the handrails when moving
- Use a private bath only within your booked slot and leave on time
- Tohoku and other regions still have many therapeutic hot springs with mixed bathing; for long therapeutic stays, follow the ryokan's and your doctor's advice
Don’t
- Don't stare at other bathers, strike up conversations, or linger to watch
- Don't take photos or videos in the bath area
- Don't overstay a private bath; the next group is waiting
Mixed bathing works only because bathers keep their eyes to themselves; staring or taking photos will get you asked to leave, and filming others in a bath may break local law.

Stay off private land, and ask before photographing children or people
Do
- Ask parents' permission before photographing their children
- Ask geiko, maiko, and other working people before photographing them
- Check for 撮影禁止 (no photography) signs, and ask staff if there are none
- Photograph trains and stations themselves without disrupting operations
Don’t
- Do not enter private homes or land for a shot
- Do not photograph the inside of homes
- Do not aim your camera at individual passengers on trains or buses
- Do not step into rice paddies, flower beds, or along railway tracks for photos
- Do not use selfie sticks or tripods in crowds or dangerous spots
- Do not chase or stop geiko or maiko
Trespassing on private land is illegal and can get you told to leave or to delete your photos. Shooting in no-photo areas will be stopped, and photographing children is seen as an invasion of privacy.

Bathe nude in the onsen and keep your towel out of the water
Do
- Bathe fully nude, without swimwear or underwear
- Rest your small towel on your head or the edge of the bath
- Tie up long hair so it stays out of the water
- Enter the bath slowly and keep quiet
- Leave your phone in the locker
- Keep your first soak short, and dry off before returning to the changing room
Don’t
- Do not dip your towel into the bath
- Do not swim, dive, or talk loudly in the bath
- Do not take photos anywhere in the bathing area
- Do not wrap your yukata right side over left; that is how the deceased are dressed
Most of these are written bathhouse rules. Breaking them gets you a reminder from staff, and in serious cases you may be asked to leave. Soaking too long can also make you dizzy.

Practical info
Travel tips
- There are many udon shops in central Takamatsu, around Ritsurin Garden and in the outskirts
- many open in the morning and close when the noodles sell out, so in the afternoon you may miss out. A bowl takes only a few minutes, so you can visit two or three shops in a day. Many famous shops in the outskirts are in the countryside and require a car, a taxi or a sightseeing udon taxi. It combines well with Ritsurin Garden, Yashima and Kotohira's Konpira Shrine. Dietary notes: the noodles contain wheat
- the broth is usually made from dried sardines and kombu and contains fish
- tempura toppings contain egg and wheat. Some small shops take cash only. Opening hours vary widely between shops, so check before you go. Prices and opening hours are set by each shop
- popular old shops often have queues, so eating outside peak mealtimes is more relaxed.
