Building an internal design capability while improving multiple products
Yamato Transport operated many digital services and business systems, but did not yet have a specialist function that could view the user experience across them and improve it continuously. I worked with internal business leaders, frontline teams, and development partners to make the issues visible, then assembled and directed a multidisciplinary design team. By creating processes, tools, and education that enabled non-designers to participate in UX design, the role of designers shifted from decorating interfaces to helping the organization make better decisions.
Making complex information accessible at the moment it is needed
This account-management app handles a large volume of information, including contracts, charges, and data usage. I redesigned its information architecture around one question: what does this user need right now? The information was organized into meaningful cards, creating an experience that helps users reach what they need without hesitation, much like receiving attentive assistance. The app received a Good Design Award in 2021.
A business that remained flat for seven years, then grew fourteenfold over the next four years
dmenu's membership had remained flat for years. I reconsidered the distance between the services the company wanted to provide and the experience users actually received, then reorganized user goals, information priorities, and navigation to rebuild the information architecture and customer experience. The result made the reason to use the service clear and created a structure through which users could continue receiving value.
Connecting a new points experience to business growth
QIRA Points is a new rewards program for Daimaru Matsuzakaya Card. Beyond designing a system people could use with confidence, I created the experience from concept through screens and operations so that discovering, earning, and using points would feel enjoyable. The card, points, and in-store experience were connected as one relationship.
Adding the value of a new digital experience to everyday life
I designed an app connected to the Barista home coffee machine that lets people adjust coffee strength and froth to their preference. Rather than treating it as a remote control, I framed it as an experience for enjoying a personalized cup each day, connecting the physical product and app into one continuous experience.
