12372 Kagesuke           Discovered 1994 May 6 by T. Kobayashi at Oizumi.
Shibukawa Kagesuke (1787-1856) was chief of the Edo National Astronomical Observatory in Edo, Japan, from 1809 to 1856. His main field of interest was positional astronomy. He studied the calendar computation method "Tenpou-reki" to reform the calendar in use at the time.
