During the period between 1968 and 1987 there were 27 records of <i>Nyctea scandiaca</i> from Hokkaido, northerhmost island of Japan. Some of them were observed in summers. More birds were recorded in 1977 and 1983-84 than in other years. In 198344 more owls wintered also in Kamchatska. These facts suggest that a part of owls wintering in Kamchatska and Hokkaido in 1983-84 remained there in 1984.
