後北条氏 The late Hojo clan

This is the tomb of Hojo Ujimasa and Hojo Ujiteru in Odawara.
They were ordered HARAKIRI for the responsibility of the siege of Odawara 1590.
The late hojo clan governed almost all konto region. 
Finally the clan surrendered to Toyotomi Hideyoshi.
at the time they had meeting endlessly. but it didn't reach the decision.
we call endless meeting to no decision Odawara byoujou.
It's the same expression at Congress of Vienna: Der Kongress tanzt, aber er geht nicht weiter
