I am trying to understand the history behind Tenkara. The problem is there is really only one book in english that can be had. The other problem you have is when you ask some people what Tenkara fishing fishing is they tell you what the so called Masters told them. They try to pass that off as traditional tenkara. To me it is Moderen Tenkara Fishing in Japan and not Tradition. It has been evolving since the beginning. To me I love the simplicity and ease of this style of fly fishing. Not overly complicated and can be adaptive to most every condition you come across while fishing.
