Established in 1981, this restaurant's signature bukkake udon, featuring firm, square noodles coated in dried sardine broth, is known as the "original bukkake udon," born from staff meals. The noodles, foot-stomped and hand-cut, are expressive and smooth, with a refreshing texture. Seasoned with lemon and grated ginger, this classic tasting udon embodies the essence of Kagawa.

Yamashita Udon's bukkake udon is characterized by its chewy noodles, made using round rice flour from Kagawa Prefecture. The broth is made by slowly simmering dried sardines from the Seto Inland Sea, resulting in a rich flavor.

The restaurant is self-service and has a good turnover. In addition to the standard kake (soup topping), zaru (cold udon), and soy sauce (soy sauce) options, there's also a wide selection of sides like kakiage (fried tempura), toriten (chicken tempura), and oden (stewed stew). The thick, sweet and spicy tofu from nearby Horiguchi Tofu Shop is a highly popular topping among connoisseurs. The route is easy enough for travelers to follow, making it extremely convenient for both family trips and solo activities.

It's about a 10-minute drive east from Zentsuji.
