La Collina in Ōmi-Hachiman is a truly unique and charming spot. This confectionery factory-turned-restaurant features a hill-like roof covered in grass, giving it a whimsical and natural feel. The building itself seems alive, with a meticulously maintained patch of grass on its roof. Witness the craftsmanship behind the making of these treats firsthand, as almost every part of the building features glass walls through which you can see the whole process. A must-visit experience for any traveler seeking a delightful and memorable encounter with Japanese design and confectionery.
