On third day of company trip to Japan, we went to Kumamoto castle which is in the centre of the city. It is surrounded by beautiful nature as stream, and modern buildings aside. Although some buildings were under construction or rebuilted because of the war 100years ago, the streets of zigzag shape were between tall huge walls. When most of people were amazed by the buildings above the walls, I couldn't take my eyes off from the curves of walls. They were built to defend from the enemies on purpose, and it made magnificent views also.
