The southern rim of Bunin, as well as the floors of two smaller craters at the center and on the northeastern rim of Bunin, are in permanent shadow. Within the shadow of the southern rim is a "small-scale cold trap" where water-ice may be exposed at the surface.[2]
Bunin is northwest of Josetsu crater.
