Masami โTenkara no Oniโ Sakakibara โ the Tenkara Demon โ is widely recognized as one of the worldโs top tenkara master anglers. For over a decade, the crew at Tenkara Guides LLC (Erik Ostrander, John Vetterli, and Rob Worthing) worked to share Masamiโs style of tenkara fly fishing with the world. Their main event was the Oni Tenkara School. Each year, the Tenkara Guides hosted Masami and his wife, Coco, on the Blue Ribbon trout waters of Utah to teach his unique, highly effective tenkara style. Schools with Masami were both incredibly instructive and a heck of a lot of fun, but it couldnโt go on forever.
Eventually, travel to the United States became too much for Masami, so he passed the torch to Erik, John, and Rob. Robert M.C. Worthing, M.D., is a certified fly fishing guide and founding member of Tenkara Guides, LLC. An avid outdoorsman, academic physician, and Navy veteran, he has appeared in a variety of fly fishing magazines, books, television shows, and events at regional, national, and international levels. A devoted member of Team Oni U.S.A., Rob is one of only three students in the United States to earn Masami Sakakibaraโs approval to instruct the Oni school of tenkara fly fishing.

Now, Rob Worthing has published a collection of lessons learned directly from Masami in a book called Demonโs Game: The Oni School of Tenkara Fly Fishing. โI set a lot of goals for this bookโ, Rob told Tenkara Angler, โbut the biggest one was to honor Masamiโs fly fishing legacy.โ The book reads like a sort of syllabus for the Oni Tenkara School. It starts with a new look at the history of tenkara in Japan and Masamiโs place in it, outlines a philosophy for Oni tenkara, and dives into technical chapters on trout, the water they live in, and the bugs they eat. Then comes the meat of the book โ a comprehensive outline of the Oni school of tenkara, including fundamental and advanced fly presentation, movement and dissection of water, strike detection and hook set, playing and landing fish, and more.
โI didnโt want to try and speak for a master angler like Masamiโ, said Rob. โDoing that would be disrespectful. I had to write the book from the point of view of Masamiโs devoted student. Iโm a technical kind of angler, so a lot of the book is technical. Thereโs a lot of science, because learning about nature and then applying what you learn on the water is a big part of what makes fly fishing beautiful to me, and I think to Masami. There arenโt a ton of basics in this book, like how to tie knots. There are plenty of good tenkara books for that. What we were missing was the advanced stuff.โ

The book is dense with useful facts. Technical chapters benefited from review by a host of experts, and the book includes sections on rods, lines, flies, and troubleshooting topics like casting, wind, and floating or sinking the fly. And all of it is beautifully illustrated by Jim Tignor.


โThis is the kind of book I hope people will read multiple times, go back to and reference. Masami and his Oni tenkara are the stars, but the book is really filled with stuff that everybody in fly fishing needs to know, whether youโre fly fishing with a tenkara rod or not. Itโs the kind of book that can make you a better angler.โ
Demonโs Game: The Oni School of Tenkara Fly Fishing is available direct from the publisher and on Amazon.

“Iโm a technical kind of angler, so a lot of the book is technical.” I smiled when I saw that phrase. It’s an apt description of Rob. However, he is really good at demonstrating what he talks about plus being a hoot to fish with. I’m really looking forward to my book showing up.
Hi!
Is that book available only on Amazon?
I’d like to buy one, but it says it doesn’t delivers in France.
Any chance this will change?
I ordered directly from the publisher.(Kendall Hunt) and it is on its way. I had to pay shipping but I avoided doing business with Amazon.
Yep, Jeff Bezos has enough money and (too much) influence already.
Thomas, it looks the publisher will ship to France: https://he.kendallhunt.com/product/demons-game-oni-school-tenkara-fly-fishing
A way to avoid both Amazon and the publisher’s shipping charges is to order the book from Walmart. Same price as Amazon, and Walmart ships for free (at least did to me):

Or, word is that Rob will have copies of the book for sale at the Driftless Tenkara Campout, May 1-3.
Rob is a one-of-a-kind angler, and this is a highly recommended, one-of-a-kind book. And the first 65 pages are of value to any stream trout fisher, not only tenkara anglers.
