UX Research

Recently, I visited the Van Gogh exhibition at the Tokyo Metropolitan Art Museum. As I stood facing his portraits and landscapes, I was reminded of an essay by a philosopher I had read long ago.  That one essay focused on a simple painting of “Pair of Shoes” by Van Gogh. Philosopher Martin Heidegger once wrote that these shoes are not […]

PMDA’s overall HFE mindset is aligned with international regulatory frameworks, but expectations in certain areas can differ. In particular, PMDA takes a distinct approach to topics such as sample size determination and test environment considerations. This guide outlines key points based on the implementation of JIS T 62366-1:2022 and current PMDA expectations.  Sample Size  PMDA does not […]

Today, I’d like to begin this blog with a simple question.  What does “the best user experience” mean to you?  If an answer came to mind right away, it’s probably because that experience moved you so deeply that it engraved itself into your memory. And yet, the more powerful an experience is, the harder it often becomes to explain why it […]

As a UX researcher, I’m trained to observe the subtle ways people interact with the world. Within the last few years, a fascinating pattern has emerged among my peers, friends, and in my own digital life. It’s a four-letter code that has become a new kind of language: MBTI*.  * Short for the Myers-Briggs Type Indicator, a self-reported questionnaire that assigns people to one of 16 […]

One-on-one in-depth user interviews may be the bread and butter of many UX researchers, but group interviews and workshops create a unique opportunity of observable collaboration, negotiation, and debate. When facilitated well, these sessions become living laboratories where one person’s idea can collide or react with another’s, creating new and unexpected findings. The key is to use group interaction itself as a source of data. Achieving this requires a thoughtful […]

In UX design and research, we frequently deal with the concept of time. When we create customer journey maps or refer to frameworks proposed in the “User Experience White Paper” (Roto et al., 2011), we often divide experiences into phases such as “before use,” “during use,” and “after use.” Breaking complex phenomena into manageable phases can be extremely useful in day-to-day […]

The Cashless Paradox  For any global visitor, Japan has long been a land of fascinating contradictions: a nation of futuristic bullet trains and talking toilets that, until very recently, ran on physical cash. As UX researchers in Tokyo, we’ve had a front-row seat to the dramatic unraveling of this very paradox.  If we turn the clock back just seven […]

In the world of UX, we’re often obsessed with a frictionless experience. We strive for usability, speed, and seamless journeys. These are vital, of course. But in our quest for efficiency, are we forgetting something more fundamental? The human experience of choice.  Every day, we click, decide, and act through user interfaces. But how free […]

Words like emoji and otaku have entered the global business lexicon, each offering a unique window into Japanese culture. It’s time to add a new one to your list: Oshikatsu (推し活).  On the surface, Oshikatsu might look like simple fandom. It translates loosely to “supporting one’s fave,” with “oshi” (推し) being the favorite idol or […]

Fireworks as More Than a Spectacle  For many outside Japan, hanabi (花火) are simply a beautiful pyrotechnic show. But for the Japanese, they are a seasonal tradition that evokes a deep sense of summer, nostalgia, and community. What if we told you that a Japanese fireworks display is not just a cultural event, but one […]
