Self-introduction
I am from Iwate Prefecture, in northern part of Japanese main land Honshu. I majored in astronomy. I study the explosions of stars and evolution of resultant ejecta and of stellar wind in a scales of the host galaxy. I am engaged in maintenance of 1.5-m optical/near-infrared telescope `Kanata' of Hiroshima University. I also work for developing an instrument for astronomical observation, especially for polarimetry.
