Observations on hunting flights of <I>Myotis frater kaguyae</I> IMAIZUMI, 1956 were conducted in Kado (Alt. 275-450m), Iwaizumi-machi, Shimohei-gun, Iwate Pref., northern Honshu, on 4-5 Sept. 1961, 26-27 Sept. 1963, 30 Sept. 1964, 6-7 Oct. 1964, and 14-15 May 1965. In total, twelve were observed by the author, and three of them were captured for species identification.<BR>Hunting places of this species are rather narrow and flat spaces between low mountains. In these places, <I>Pipistrellus endoi</I> IMAIZUMI, 1959 and <I>Nyctalus lasiopterus aviator</I> THOMAS, 1840 were very numerous, but this species was not so common.<BR>This species generally emerges in twilight from about 5 p. m. to 7 p. m., evidently later than <I>Pipistrellus endoi</I>. These bats fly nearly straight for about 30m to 40m, horizontally and perpendicularly, at a height of about 2m above the earth, and repeat such straight flights several times. They never fly through foliage as does <I>Rhinolophus cornutus cornutus</I> TEMMINCK, 1835.
