In 1600, there was a famously bloody and pivotal battle at Sekigahara, where the Western and Eastern clans fought. This battle ended what became known as the era of the warring states. In other words, the world of Japan that we find is going through a some kind of cataclysmic, epochal change. It's a violent age, an age of deep anxiety. Though it's a very alien time and place, I feel that this era speaks to us about our own troubled times. We have our own cataclysmic changes going on, our own sense of anxiety and "uprooted-ness".
