9096 Tamotsu           Discovered 1995 Dec. 15 by T. Kobayashi at Oizumi.
Tamotsu Fujii (b. 1947) became interested in astronomy when Sputnik 1 was launched in 1957. Since then he has been an observer of sunspots. He has been a member of the Oriental Astronomical Association since 1960 and president of the Yamashiro Astronomical Association since its founding in 1962.
