97582 Hijikawa           Discovered 2000 Mar. 6 by A. Nakamura at Kuma Kogen.
Ehime prefecture's 103-km-long Hijikawa river has its source near the Tosaka Pass in Seiyo City and flows into the Seto Inland Sea. With more than 470 tributaries, the Hijikawa has supplied its abundant water to the people in the southern part of Ehime, especially for irrigation.
