Japanese men are taking the stance that women have to take on and keep the tradtional japanese woman's wife role seriously gain if they are going to continue to work and build their country.
The statue is some what of a fertility statement while simultaneously encouraging women to be good wives and mothers in the family as the statue takes on the tradtional japanese legend of the brave oni boy Kintaro.
It also encourages national heritage pride in Japan's tradtion.
I think most women in a japan might find it to be otaku but in a sense it's encouraging traditionalism and respect for women.
Modernism for women degrades them and destroys society.
