I am a Smalltalk programmer in Japan. I organised Japanese Squeak communities Squeak-ja and Squeakland.jp with friends. And I'm a member of Squeakland Foundation. I have conducted many Etoys workshops.
I created a small sensor device named the "World-Stethoscope" for science exploration.
I teach at the Cyber University and some real universities in Japan.
I translated Scratch and its materials into Japanese with friends.
