Located along Prefectural Route 6, "Dried Sweet Potato Specialty Store Daimaruya" is marked by a large stone statue of a Hoshi-imo (dried sweet potato).Inside the spacious, hall-like store, they reportedly stock over 30 varieties of Hoshi-imo (dried sweet potato), including different shapes such as flat slices, round slices, and sticks.

Hoshi-imo (dried sweet potato) and How to Enjoy Gelato
Hoshi-imo (dried sweet potato) offers a perfect balance of softness and sweetness, and the dried whole sweet potatoes are reportedly carefully selected for their exceptional tenderness before being packaged. In addition to the classic “Beni Haruka” variety, they also carry rare varieties such as “Healthy Red” and “Komachi,” allowing you to enjoy the distinct flavors of each variety.
You can add toppings to the gelato (PN0), and in addition to the classic milk flavor, flavors that highlight the natural taste of sweet potatoes are also popular. The rich flavor of sweet potatoes spreads throughout the refreshing texture. This is an original gelato unique to Daimaruya.
