ABOUT mui Lab

(page title)


Promoting calm technology to achieve more humane digital living



Achieving harmonized beauty, both inside and outside of our products


Uncompromising pursuit of truly calm digital living


Collaborating with different stakeholders to together foster calm digital lifestyles


mui Lab was founded to promote societal adoption of “calm technology” – the technology that fits in with natural human behaviors and environment. Designed with users’ comfort and happiness in mind, calm interfaces can further bring out the humanness of human life. Taking inspiration from the successful blending of traditions and technology in our home city of Kyoto, we draw upon our designing and engineering expertise to put forth novel visions for the next generation digital lifestyle that enhance our total well-being.

Calm Technology & Design

mui Lab integrates digital technology into systems and devices in such a way that it feels like an innate part of natural human behaviors as well as our environment. mui Lab envisions digital living in which technology performs in a perfect harmony with humans. To make this a reality, we tap into the design concept of Calm Technology, first proposed by American scientist Mark Weiser, in combination with the Japanese sense of beauty to create systems and devices that turn technology into seemingly innate part of our lives and environment.

mui Platform

“mui Platform” is a vehicle with which to achieve calm digital living. It consists of mui’s patented wood display panel – our flagship “calm UI,” or a peaceful touchpoint between humans and technology – and our proprietary IoT cloud system. The use of natural wood as the material of the interface provides users with a sense of beauty and comfort. Because the calm UI is designed to blend into users’ surroundings, it enables distraction-free communication and easy access to your most important information only.

mui Lab holds a number of patented technologies that turn natural materials into touch-sensitive display panels. These technologies, together with mui’s proprietary Design Principles based on the Calm Technology & Design concept, serve as the foundation of all our product development.



As the name suggests, our business began as the calm technology “lab” where our flagship interface, the mui board, was born. While we continue to create our own products, we are now also focused on developing calm IoT systems for our clients to help them solve their problems with the use of calm devices. These systems – all of which are built on our “mui Platform” – are designed to provide peaceful digital experiences for users. We draw upon our expertise in the designing of system architecture, applications and UIUX, as well as product design, and business development, to provide total solutions, from suggesting new service products to real-world implementations of solutions.

Customer Experience Creation



We are a diverse team of professionals whose collective expertise – ranging from system architecture to designing to business enterprise – enables us to provide a broad array of services to help you live a calm digital life. We believe the technology of the future is one that fits in seamlessly with our natural human behaviors and environment, making users happier by further bringing out the humanness of human life. We are committed to provide “truly calm” technology and systems that focus on users’ emotional well-being.

        Ebisugawa Salone

        “Ebisugawa Salone” is a third place that we opened in July 2020 on Kyoto’s historic furniture district, Ebisugawa Dori, to demonstrate our vision for new lifestyles. The venue has since hosted many different types of events, including art exhibits and live performances, serving as a gathering place for local residents and artists who feel isolated due to the pandemic. We hope that people will be able to feel the richness of calm digital living when they visit Ebisugawa Salone.
