I am a Japanese citizen based in Tokyo, Japan. The “Outstantding Super Creator” qualified by IPA (Information-technology Promotion Agency, JAPAN), working in software/hardware engineering and designing at the field of Human-Computer-Interaction (HCI). Gained Master from The University of Tokyo in 2011. I am interested in intersection of engineering, science, design and human to invent new ways of interacting with computers. My primary interest is how to bring the REAL world to computer world and how you bring computing to the REAL world. I have experience in software developing, prototyping, designing for physical, interactive UIs and researching HCI.

Chrome Extension for reporting TEPCO’s power usage

After the Tohoku-Chihou-Taiheiyo-Oki Earthquake and tsunami struck our country nation on March 11th 2011, Tokyo and its urban area faced a power shortage. I built Chrome Browser extension for reporting power usage of TEPCO(Tokyo Electric Power Company) in toolbar of Chrome browser. It was released in a day after TEPCO starting to disclose power usage. Currently, more than 5000 users use this extension.
