This award is granted to residential series and corporate initiatives demonstrating outstanding energy-saving performance, with comprehensive evaluation based on insulation performance, airtightness, equipment efficiency, energy conservation, and comfort. Yamada Homes was highly commended for its promotion of high-insulation and airtight homes, standardization of high energy-efficiency specifications, and efforts toward creating comfortable indoor environments.

At Yamada Homes, we are committed not only to pursuing energy efficiency but also to realizing homes that:

- Reduce household utility costs

- Offer long-term durability for安心 living

Our custom-built home series 'RASIO,' which received this award, comes standard with IoT specifications across all units. In the television commercial featuring actor Ken Watanabe, which has been airing since March 2026, Watanabe personally experiences the comfort and functionality of an actual Yamada Homes smart house, conveying the message: 'Because you can experience it firsthand, you can trust it.'

In the commercials, Watanabe visits Yamada Homes exhibition sites and experiences the smart house in person.

Moving forward, we will continue to contribute to our customers’ enriched lifestyles and the realization of a sustainable society through homes that balance high performance with ease of living.
