Feeding activity in relation to atmospheric temperature and precipitation of the Japanese toad, Bufo japonicus japonicus, during the non-breeding season were studied in the botanical garden of Kanazawa University from 1973 to 1979. Toad activity was influenced remarkably by rain. On rainy nights many toads appeared on the ground and hunted earthworms, snails and insects, but on cloudy or clear nights most of them stayed in their hiding places. Two or three mm. precipitations after several days of fine weather brought out many toads from underground. On the other hand, when rainy weather continued for several days, active toads decreased in number. It may be assumed that feeding activity of the toad is not only controlled by environmental factors such as rain, but also by his own conditions such as hunger.
