Physics education of Japanese national colleges of technology in local community of Hokkaido

The national colleges of technology in Japan, called KOSEN, were established about 50 years ago aiming to educate 15 to 20 years old students to become engineers who were necessary in period of high economic growth of Japan. In present, environment surrounding us has changed. Examples are low birth rate in Japan and the great earthquake in Tohoku area. There are 4 KOSENs in Hokkaido and we jointly make many efforts to contribute to local community in science. We present our efforts in physics education.
