The Kamikatsu Zero Waste Center.

The first zero-waste eco-hotel 'HOTEL WHY' is part of the 'Kamikatsu Zero Waste Center.' Kamikatsu Town in Katsuura District declared its goal of achieving zero waste in 2003, becoming the first municipality in Japan to do so. This led to the construction of the 'Kamikatsu Zero Waste Center,' aiming to create a sustainable zero-waste society. The center uses discarded windows and various local building materials from Kamikatsu to minimize pollution from transportation. The design is also interesting, allowing visitors to connect with nature and learn about waste sorting.
