I was born on December 22 in 195..in Kagoshima prefecture.
I became interested in astronomy in the latter half of my elementary school years. My association with telescopes began when I made a single-lens refractor. Later, I bought a 4cm f/10(?) Newtonian and was impressed with the optics free from chromatic aberration.

In junior high school days, I purchased Carton Optics's equatorial comet seeker (6cm f/6?) refractor and started astrophotography, too. Around that time, Kumamoto Astronomical Society was founded and I joined them right away. Soon after, I built a 10cm f/6 Newtonian. I also joined Hoshino-hiroba, a national organization of comet observers.

Graduating from senior high school, I entered university and my interest in astronomy waned. But, at the apparition of Halley's Comet, once again I became an astronomy enthusiast overnight. A colleague bought a 15cm reflector to observe the comet and we lugged it to Hiraodai in northern Kyushu. We had a "grand" star party with scores of people joining us.

I was inspired by Comet Hyakutake in 1996 and regained passion for astronomy. Anticipating the close approach of Comet Hale-Bopp, I purchased, through the Internet, Takahashi's equatorial telescope (Space Boy) which I had long been dreaming about. Needless to say, I was completely engrossed in astronomy.

In September 2000, I was able to get to know many people by the establishment of this website. Later, I transferred my homepage to a rental server, when the visitor counter reached 200,000.

My occupation involves looking into micro- and nano-worlds. Both my work
and hobby of astronomy happen to make me peek into the worlds of mystery.
