In the 1970s, Japanese government and business people were very concerned that a rise in the value of the yen would hurt export growth by making Japanese products less competitive and would damage the industrial base.
Na década de 1970, o goberno xaponés e os homes de negocios estaban concienciados de que unha subida do valor do ien danaría o crecemento das exportacións, xa que faría os produtos xaponeses menos competitivos e iso danaría a industria.
