In Tenkara Today, Morgan Lyle weaves various threads of tenkara fishing, gear, early adopters and upstart companies to describe just how tenkara got to where it is today in the US.
Morgan Lyle is unquestionably the best person to put that all on paper. He was there from the beginning.
has been intimately involved in tenkara from that moment on. He knows
all the players, and not being a competitor, he gets all of them to
talk. I was there from the beginning, too, but there's a lot in Tenkara
Today that I didn't know.
Dr. Kevin Kelleher and Ms. Misako Ishimura (both tenkara anglers) have written an introduction to tenkara for American anglers.
As an introductory work, which the first English language book on tenkara pretty much had to be, it covers a lot of different topics without going into extreme detail on any one of them. The origins of tenkara (at least to the extent they're known) are covered, as are the gear, the knots, techniques, flies, lines, backpacking with tenkara and tenkara for women.
Many of the fishing techniques outlined go beyond the scope of
tenkara as practiced in Japan, but will resonate well with American
anglers. More info...
The term most used to describe tenkara is "simple."
Fellow tenkara angler Morgan Lyle has gone one better and has written a book on simple flies. There are some tenkara flies in the book, the iconic Ishigaki and the Takayama Sakasa Kebari, and some, like the CDC & Elk on the cover and the Stewart Black Spider (the first of the 52 patterns) that are not Japanese tenkara flies, but are certainly simple flies that work very well with tenkara rods. And of course, my favorite, the Killer Bug, is in there as well.
