The way of thinking that men are superior to women is entirely outdated

The origin of a housewife is from England in 19th century. The stream of customs that woman needs to be steady housewife to support their husband and family spread around the western countries.

When TV became widespread in Japan after WWⅡ Japanese people increased the opportunities to watch American domestic drama which appeared housewife in the highlight scenes so we Japanese were influenced by one of the lifestyle of housewife for women then.

But now women’s empowerment has become prevalent into various kinds of industries so working couple is very standard work style in modern society. England also has passed the period of time when housewife was thought to be one of the best women's lifestyle so such a lifestyle as not having job or lifework and staying home all day was neglected by the younger generation today.

The reason why the Japanese society has been struggling to find the way out of the problem of decreasing birthrate and aging of the population is because the environment surrounding women is seriously bad in Japan.

I think the governmental policy of sexual division of labor which was pushed forcibly to nations was one of the measures to expand the national interest in pre-war stage when measures conducive to the wealth and power of the State was held up by the government.

At the time of Japan's defeat and renunciation of holding army in the end of WWII, the necessity of sexual division of labor should have been out of order. Moreover, such a time came to an end at now as automatic salary increase by proportion to seniority were guaranteed by a company regardless of whether men had ability to earn or not from high economic growth period to bubble economy period so it is pretty difficult to maintain the system of housewife these days.

When we think about environment surrounding Japan, I would rather accept the situation like wife is the biggest earner and hard worker on the promotion track in a company and husband has part-time job and has another aspect as house-husband. However Japanese companies keep having own standard that men must work as full time worker and women must work as part time worker.

It's quite natural thing that men don't bear child. The thing Japanese companies need to be required is to prepare steady guarantee of childbirth for women at the same time they need to strengthen the treatment for women to give an opportunity to build their career in a company, which totally helps reconstruct economy and find a solution of declining birth rates.
