    ENGLISH: This report deals with the Japanese longline fishery for tunas and billfishes from 1967 through 1970, extending the studies made by Kume and Joseph (1969a, 1969b). The distribution of effort and catch is discussed and evaluated, and the changes in apparent abundance are examined. An analysis is made of the sexual maturity and size composition of the fish, and a brief comparison of the size composition of the catches from the longline and the surface fisheries is included.
