I was born in Osaka in 1975, grown up in Osaka, sometimes lived in Tokyo, US-IL and US-CA, and currently live in Osaka. I received my B.S. and M.S. in Engieering Science from Osaka Univeristy in 1998 and 2000 respectively, and Ph.D. in Engineering from the University of Tokyo in 2003, where I studied artificial intelligence. I joined the faculty of Osaka University in 2004 after spending a year as a post-doc at the University of Tokyo.

Research Abstract

Our laboratory (Shikake lab) focuses on Shikakeology.

A "shikake" is an embodied trigger for behavior change to solve social or personal problems. I coined the term "Shikakeology" as a science of shikake in order to understand the underlying mechanisms of shikakes.

For example, the tiny shrine gate reminds people of a holy place, and this prevents them from littering. The stairs decorated like a piano, on which people can actually make a piano-like sound with their feet, attract people’s attention and encourage them to use the stairs rather than escalators.

So far, we have implemented many shikakes, such as a trash bin with basketball goal, a lion-style automatic hand disinfecting apparatus, and so on. Throughout these researches, we are attempting to construct theories and methods of behavior change in order to make the world better.


The logos of our laboratory (a.k.a. M seminar or Shikake lab) are as follows.
