He was most great emperor in Japan finally.

His grandfather was a king of “Mikawa area”.

And his father,too.

Now this area is East of Aichi prefecture.

But his father was dead in accident.

The kingdom was disappeared.

Neighber kingdom “Imagawa”and “Oda” were very strong.

So,He lived as a dependent prince, very long time.

He learned politics and military very hard. He never gave up.

Little by little, He improved himself.

Finally, He took “Okazaki castle” back.

He became independent king.

After that He used “strange strategy”.

I will explain about this matter later post.
