9226 Arimahiroshi           Discovered 1996 Jan. 12 by T. Kobayashi at Oizumi.
Hiroshi Arima (b. 1958) is a registered architect who also designs individual observatories in Japan. While a university student he was a leader of the Kyushu Meteoric Network. With members of the Kumamoto Civil Astronomical Observatory, he helped carry out a solar eclipse observation in Mexico in 1991.
