Starting in June 2026, the DAN Panel will be newly added to the lineup of RASIO, the company's flagship custom home series, enabling the realization of homes with both superior seismic resistance and flexible interior layouts.
With over 130,000 homes built over 41 years and zero instances of total or partial collapse due to earthquakes, the technology behind the DAN Panel builds upon the proven wood-adhesive panel system developed through the S×L structural method and traditional post-and-beam construction.
## Development Background: Stronger and More Flexible
To meet growing customer demand for both enhanced seismic safety and open, customizable living spaces, Yamada Homes spent approximately three years researching and developing a new construction method that fuses wood-adhesive panel technology with traditional post-and-beam framing.
The name 'DAN Panel' encapsulates four core values: protecting family togetherness (DAN), strength and dynamism (Dynamic), shock absorption (Absorb), and creating a nurturing, enveloping home (Nest).
## Four Key Features of the DAN Panel
- Full-Surface Load Distribution via Adhesive Panel Method
Leveraging wood panel bonding technology refined since the S×L era, the DAN Panel uses high-durability adhesive—rated for a service life of up to 100 years—to bond the entire surface. This allows the entire structure to absorb and distribute seismic forces efficiently.
- High Structural Strength with a Wall Multiplier of 4.9
The DAN Panel achieves a wall multiplier of 4.9, offering exceptional strength. Thanks to the adhesive panel technology, it maintains high durability even under repeated seismic shocks, eliminating the need for additional seismic dampers.
Furthermore, to enhance constructability and safety, the panel has received MLIT certification under the 'floor-first' construction method. This involves fully installing structural plywood on the foundation and beams before erecting walls, ensuring a stable base for wall panel placement.
- Factory-Produced for Guaranteed Performance
Panels are manufactured in-house with precision down to less than 1mm, ensuring consistent quality. Additionally, insulation materials are pre-installed at the factory before on-site delivery, minimizing gaps between insulation and structural elements that commonly occur during manual installation. This enables the delivery of highly comfortable homes meeting Thermal Insulation Grade 6 standards (UA value: 0.39).

- Enabling Open, Flexible Interior Design by Reducing Internal Walls
By strengthening shear walls along the building's perimeter, the number of interior load-bearing walls can be minimized. This allows for spacious, open-plan living, dining, and kitchen (LDK) areas that foster family interaction, all while maintaining Seismic Grade 3 compliance and enabling efficient home layouts.

By increasing the wall multiplier of perimeter shear walls, interior floor plan flexibility is achieved without compromising Seismic Grade 3 standards.
