5777 Hanaki           Discovered 1989 Dec. 3 by Y. Mizuno and T. Furuta at Kani.
Many years ago, Yoichi Hanaki (b. 1937) used to make astronomical observations, notably of Jupiter, with the second discoverer. Later he established the vocational training facility Hoshi-no-mura that endeavors to help mentally handicapped people.
