A Tokyo-based startup has secured seed funding of 3 billion yen (about $21 million) to advance its Living Home platform, which fuses residential construction with AI, robotics, and software to support future domestic robots.

Early market traction is evident, with the first Living Home in Tokyo’s Himonya district receiving a purchase offer soon after sales began, over 1,000 inquiries, a second project in Fukuoka, and three more homes under construction in Kanagawa Prefecture expected to be completed soon.

Currently, more than 10 Living Home projects are underway across various locations in Japan.

The company lays out four main initiatives: expanding deployments beyond the current projects and locations, creating a centralized Living Home platform to manage devices, services, and future robotic systems, accelerating AI robotics development with a data center built from real-world residential data, and licensing the platform to other builders while growing the team across engineering, architecture, real estate, and business functions.

Funding will be deployed to broaden Living Home deployments nationwide, advance residential AI and robotics tech, construct data infrastructure for training AI models, and license the platform to additional builders and developers.

A core goal is Residential Physical AI, enabling homes to perceive their environment, make decisions, and coordinate actions with minimal human input through sensors, AI systems, and connected devices.

The seed round attracted a mix of prominent investors including Alpha, Spiral Innovation Fund, SMBC Edge, Mitsubishi UFJ Capital, and notable individuals such as Rakuten co-founder Shinnosuke Honjo and Susumu Omori.
