When I went to the Ueno park, I also went to the Tokyo National Museum.
And then it has exhibition of The National Treasure ASHURA and Masterpieces
I was not interested in Ashura but 10000people visited in first day of this exhibition. Because of that I just went to there. :P
So then why 10000people wanted to see Asura?
Well the reason was this:
this is the very first time that nomale people, like me, can see Ashura,
he Devas of the Eight Classes and the Ten Great Disciples of Buddha.
They used to be only the temple of Kohfukuji.
So that is why people want to see it.
By the way, ashyra, which has three face and six arms, is a guardian deity.
Why it has three face and six arms? I don't know :P
