At the heighest point of Japanease national road. (September 2006) I came all the way from Tokyo by this non-geared ordinary bycicle. It's 2172m above the sea level!!!		Sunrise from the top of Mt.Fuji (August 2006)
Enjoy skiing at Matterhorn (January 2008)		Programming training at the top of Mt.Fuji (September 2008)
I studied in Applied Mathematics Dept of TU-Delft in Netherlands as an exchange student. (April 2007 - March 2008)		I visited computer science departemnt of the Columbia University (April 2010 - March 2011)
