This report studies the effects of contraception and abortion on crude birth rate (CBR) and total fertility rate (TFR) in Japan from 1947-1980. The CBR declined from 34.3 in 1947 to 17.3 in 1957, and the TFR from 4.5 to 2.0 in the same period. Both stabilized (CBR in the range of 17.0 to 19.0 and TFR at 2.0 to 2.1) between 1957 and 1973. This dramatic decline in fertility was initiated under the serious socioeconomic difficulties of post-World War II Japan. At the onset of the postwar fertility decline, fertility within marriage was controlled most strongly by induced abortion, and to a lesser extent, lactation and contraception. During the period of stable low fertility (1960-1980) the effect of abortion decreased and the effect of contraception increased. KAP surveys show that in the late 1970's more than 75% of contraceptive users in Japan employed the condom, while condom use in other Asian countries is generally very low. A shift from traditional to modern methods of contraception is unlikely to alter the already low level of fertility in Japan but would have considerable social, medical, and economic impact.
