It cannot be said that in the earlier history of the island nation, women were not at all among the highest State. At least seven empresses are known, some of whom have left a memory in their own right that has reached several millennia and to the present day. However, the first woman of the weak sex to hold an official position in the government of Japan’s modern state power structure did not appear until 1960. It was a period of rapid development of the country and its re-integration into the world community after its defeat in World War II. It was this process that significantly influenced the involvement of Nakayama Masa, the daughter of an American entrepreneur educated in Japan and the United States, by then becoming an MP the lower house of the Japanese parliament. On July 19, 1960, she was appointed Minister of Health and Welfare in the government of Prime Minister Haiyato Ikeda. It was in memory of this event that the Day of Women Ministers was later established.
Since then, on average, two Japanese women have been on the list of ministers of each government of the country. And in 2007 there was no less significant event than in 1960 – the minister of defense in the country of samurai was a woman, Yuriko Koike.
