Sakaeya is right across Tobu Nikko Station, and it sells their original Ageyubamanju that can only be found at their shop.
This delicious product is a bun filled with anko (red bean) paste, wrapped in yuba (tofu skin), fried, and finally salt-topped. This sweet and savory combination may seem unusual, but it’s uniquely tasty. And only 200 yen a piece!
Address: 10-1 Matsubaracho, Nikko
