The name of the museum you went to is very interesting. "Tsunami Museum", there is an artificial tsunami sound record. This is quite a new thing that I saw here. It is very far from your area, you have to travel for about 6 hours, only then you reach there. This shows that the Tsunami Museum will be really very beautiful, which is worth seeing. For you are traveling so long. I completely agree with you that deep secrets of our history are hidden in museums, which we all are excited to know. Best wishes to you.
