2. What to know when choosing a Mizusawa udon shop
Mizusawa udon is a meal that ends at midday, and some shops close when they sell out. Tamaruya, Shimizuya, Masuya and all Osawaya shops say they close when the udon runs out. If you drop by on a day you stay at Ikaho Onsen, plan to arrive before noon so you have a choice of shops.
The shops are in Mizusawa, Ikaho-machi, Shibukawa City, in front of Mizusawa Kannon temple. By train, take a Gunma Bus bound for Ikaho from JR Shibukawa Station for 20 to 30 minutes and get off at “Mizusawa.” From Takasaki Station, a Gunma Bus bound for Ikaho Onsen takes about 1 hour. By car it is 20 to 30 minutes from Shibukawa-Ikaho IC on the Kan-Etsu Expressway, which you take from the Tokyo direction.
Some shops change their hours in winter. From January 5 to around mid-March, Matsushimaya shortens its hours to 10:30–15:00 (last order 14:30) and closes on Thursdays and Fridays. Yamagen’s kamaage udon (udon served in its cooking water) starts in December.
For dipping sauce, Mizusawatei has sesame and soy sauce, and Iwatoya has soy sauce and sesame-miso. For people who do not like sesame, Shimizuya serves a soy-sauce dip.
