Fairly tale of Japan from ancient time

Like the story of Adam & EVE,
Japan also has a story how the country of Japan was born.

I read the book and found the interesting point.
The story how Japan was born is full of wonder for me.

The story has hidden gender issue, unique concept for god,
irony, etc.

For example, here is a part of the story

------------
There was a couple. the man is called "izanagi"
the women is "izanami".
They tried to bear Japan to meet each other
coming from different direction each other.
Then Izanami talked to izanagi at first when
they meet. can you imagine what was happen then?
Yes, some island was born when izanami talked to izanagi.
But the thing is that the iland was not enbough to
be a part of Japan. Meanwhile the island was not
worth to the place to live human. They failed to
creat Japan.
Izanagi and izanami again work on bearing Japan,
This time, Izanagi tallked to izanami fist when
they meet coming from different direction.
Then they succeeded in having proper islands
which deserve to be a parts of Japan. Consequently
They could creat the country of Japan.

----------------------

Why?
Why the creating Japan was succesfull when men talk to women first?

Actually this story of Japanese Genesis is written in
7th century under political purpose of a emperor at that time.
To prove that the emperor follows god, he needs the story
people can believe.And people will obey the emperor if they
recognize the godhood of emperor.

It is not difficult to imagine there have already been an idea of
gender in 7 th century in Japan because the job function for
each gender has already divided clrealy then. As usual, man works outside
and women inside at home.
But I wasn't sure that even there was the differnce in job function between
men and women, the gender issue hadn't so much focused as that affect the
Japan genesis story even it's created by political issue. This is because
we japan had god the female emperor in ancient times so I thought
Japanese basically has the idear of gender equality.

Or, the izanagi and izanami story just shows women is prettier
than they aggressively approach men?;)))

how do you think?
