In 2006 he was the first astronomer to discover a micro-lensing system outside the Magellanic Clouds and the bulge of our Milky Way. The star GSC 3656-1328 suddenly brightened by four magnitudes in two weeks time and returned to its normal brightness two weeks later. A red or a brown dwarf star passed exactly in front of GSC 3656-1328 and the gravity of the dwarf star directed more light to the observers on Earth.

He lives in Tsuyama, Okayama.
