A Premium Hinoki Timber Home in Tsukuba
This new construction house in Tsukuba City, Ibaraki Prefecture, represents the pinnacle of Japanese craftsmanship and durable, sustainable home building. The property is a 4LDK layout with a building size of 99.36 m² on a generous 196.18 m² corner plot. The key feature is its construction as a "Total Hinoki House," where every building is built entirely with Japanese cypress (Hinoki), using the wood for corner posts, intermediary posts, and the foundation. The builder, Nichiei Shōji, is a "Tosa Timber Partner Company" with Kochi Prefecture, insisting on specially selected Tosa-produced Hinoki. Company staff conduct on-site surveys from the mountain to the sawmill, and shipment and origin certificates are attached.
The property incorporates numerous high-specification features. The roof uses tiles produced by "Tsuruga" in Sanshū Mikawa, the industry's largest tile maker with a 20% national market share, known for strength against natural disasters and a durability of over 100 years. The construction employs a rigid floor method (全棟剛床), which increases the thickness of the floor substrate plywood and attaches it directly to beams, providing greater strength against horizontal forces during earthquakes and typhoons. The exterior walls feature "Micro Guard" coating, which creates a thin water molecule film to lift off dirt, washed away by rain. The foundation comes with a 20-year ground warranty, and the structure meets the highest Seismic Grade 3 specifications, the same standard used for critical disaster-response buildings like fire stations. "Platinum Seal" adhesives resist rain and moisture, and the exterior maintains a beautiful appearance long-term due to resistance to UV fading, cracking, and dirt adhesion.
Nichiei Shōji, with 83 years in business, was ranked #1 as the most reassuring custom home builder in the Ibaraki area. They handle everything from design and construction to after-maintenance in an integrated system and are confident in their knowledge of the Tsukuba Express (TX) line area. The home is also built to ZEH-level insulation grade 5 standards and is certified by the Housing Warranty Organization.
The property is situated in the Ōzone area of Tsukuba, a city renowned as Japan's premier science and research hub, home to numerous national institutes and the University of Tsukuba. A short drive away is the iconic Mount Tsukuba, a famous twin-peaked mountain considered one of Japan's 100 most famous and a popular destination for hiking, cable car rides, and stunning seasonal views.
