GRACEHOME Wild Daimyo Cedar VI: A Newly Built, High-Performance 4LDK House in Ebetsu, Hokkaido
This newly constructed detached house, located in the Wild Daimyo Cedar Town district of Ebetsu, Hokkaido, represents the pinnacle of modern, energy-efficient living. Scheduled for completion in October 2025, this property is a ZEH (Net Zero Energy House) certified home, achieving a 52% reduction in primary energy consumption compared to the 2016 energy conservation standards. It is also recognized as a Low-Carbon House and holds a BELS certification, ensuring top-tier environmental performance.
The house features a comprehensive "YUCACO" whole-house air conditioning system, powered by just a single household air conditioner unit. This innovative system maintains a consistent, comfortable temperature throughout all rooms year-round, akin to a hotel environment, while significantly reducing cooling and heating costs. The home boasts a UA value of 0.24, achieved through high air-tightness and insulation, including exterior insulation methods and slab foundation insulation. A 1st-class heat exchange ventilation system further enhances energy efficiency. An 8.65kW solar panel system is installed, contributing to the home's net-zero energy goals.
For health and air quality, a whole-house air purification unit dramatically removes PM2.5, yellow sand, pollen, and reduces airborne viruses by 99%. It also eliminates 99.7% of invisible mold spores sized 2-5μm. The property is constructed with a seismic damping structure and features LIXIL triple-sash windows. The exterior siding is protected by a 30-year warranty Platinum Coat finish. The layout is a spacious 4LDK with rooms sized at 7.5-tatami, 5.2-tatami, 5.2-tatami, and 4.8-tatami, plus a 19-tatami combined Living-Dining-Kitchen area. The house includes two toilets (one tankless), an automatic bath with re-heating function, a system kitchen with enamel panels, soft-close mechanisms, and a dishwasher, and ample storage including walk-in closets. It is also equipped with EV charging facilities and qualifies for a GX subsidy of 1.6 million yen.
The area of Ebetsu offers a blend of suburban tranquility and convenience, located just a 13-minute walk from Noborito Station on the Hakodate Main Line. An interesting local fact is that the nearby Wild Daimyo Cedar Forest is a designated natural monument, a remnant of the ancient wilderness that once covered the Ishikari Plain. The closest major landmark is the expansive Nopporo Forest Park, a vast national park perfect for hiking and enjoying Hokkaido's natural beauty.
