When I was a child, I enjoyed watching the Moon and planets with a small telescope.
I studied astronomy in the university.
I had been engaged in astronomy popularization in Bisei Astronomical Observatory, a public observatory in Okayama from 1993 to 2019.
After retirement, I am engaged in astronomy popularization by means of supporting activities of Bisei Astronomical Observatory, teaching in an astronomy club in Ibara.
In April 2021, I became the director of Bisei Astronomical Observatory again.
