If you’re interested in traditional Japanese sweets with a unique visual style, Nakazato’s imo yokan in Okegawa is something special. Unlike ordinary smooth sweet potato jelly, this version contains visible slices of sweet potato inside, creating a texture and appearance that feels slightly unusual—in the best possible way.
It’s the kind of wagashi that immediately catches your attention the moment you see the cross-section.
