Tenkara flies are an enigma. Wide variations in Japanese regional tenkara fly patterns exist, yet a few tenkara anglers in Japan use just one fly pattern. At first glance it makes no sense. Upon further reflection it actually makes perfect sense.
Tenkara flies do not attempt to match a specific insect so there is no
need to change flies as hatches change. Fish seem to be much less
selective when taking wet flies than they are when taking dries. It is important to note also that the high gradient mountain streams on which tenkara developed are not very fertile and do not have the prolific insect hatches. The fish that live there cannot afford to be overly selective.
Dr. Ishigaki settled on one pattern because he caught as many fish on it as on any other pattern - so why change patterns? (Besides, he values simplicity more than he values variety).
Hundreds of years ago, as fishermen in isolated mountain villages tied their own flies, local patterns developed - and were used because they worked. Two villages perhaps only 30 miles apart developed different tenkara fly patterns, but both flies survived because they worked. That the patterns were different didn't matter. Apparently one was as good as another - so why change patterns?
As with the two villages, two Japanese tenkara anglers may each have their own pattern that they use exclusively. For whatever reasons, each angler will have a favorite that he fishes with most or maybe even all the time. That another angler fishes with a different pattern doesn't matter. They all seem to catch fish.
And if all tenkara flies catch fish, choose patterns you like or that are easy to tie. If you tie your own flies, I show the tying sequence for the a number of flies.
When people in the US think of a tenkara fly, the fly they think of is a reverse hackle Sakasa Kebari (which basically means "backwards fly" in Japanese). Many people ask why the hackles are reversed. The reasons I have heard the most are that they are better in fast currents because the hackles don't fold back along the hook shank, or that they are easier to tie "in hand" (early tenkara fishermen didn't have vises). Personally, I don't think either one is the reason. Early European anglers also tied their swept back hackles without vises. What's more, when the hackles collapse back on the hook shank it gives the fly a perfect nymph shape.
I believe the reason the flies have the hackle facing forward is that it creates more resistance to being pulled through the water. The fly acts like a parachute under water, which allows you to keep the line tighter - off the water's surface. That's not just a guess. It is something I observed after switching from a sakasa kebari to a slim nymph one day and realized I suddenly got much more line sag.
I do not believe it is coincidence that pesca mosca Valsesiana anglers in Italy, who even now use horsehair lines and long cane rods, virtually identical to the gear used by early tenkara anglers, also use reverse hackled flies.
I am confident that the sakasa kebari style was promoted in the US as a "tenkara fly" primarily because it is different and exotic and makes tenkara seem exotic as well. After all, most historical tenkara fly patterns in Japan are not sakasa kebari. Most have straight hackles, just as our dry flies do. They are fished wet, but their hackles are not swept forward or swept back. Also, just to be clear - you don't have to use "tenkara flies" with a tenkara rod. You can use the flies you've used successfully for years.
I'm equally confident that the whole concept of "one fly" also was promoted in the US to make tenkara exotic. It is true that there are some tenkara anglers in Japan who use only one fly but it is equally true that many (probably even most) do not. And for those that do, it was not some quest to find the "One Fly" to use above all others. It was not an exercise to make them better anglers. It was just a realization that just about all flies work (in high gradient, infertile mountain streams - which are the only ones they fish) so it doesn't really matter what fly you use. Tie what you like to tie, or what you have the materials for on hand, or like Dr. Ishigaki, a simple fly that uses cheap materials and takes 60 seconds to tie. To American fly fishermen, the whole idea of "one fly" is indeed exotic Eastern Philosophy. To the Japanese, it's just fishing.
To American fly fishermen who were attracted to fly fishing because of the flies, and who love the variety and the challenge of identifying hatches and trying to match them, taking all that away makes tenkara a pale shadow of the sport they love. Rest assured, if you want to match the hatch you can. If you want to dries you can and if you want to fish heavy woven Czech nymphs you can (although you'd do that better with a keiryu rod than with a tenkara rod).
For a new angler, however, struggling or overwhelmed by the complexity, there's no need to start learning latin. Pick a fly or two and concentrate on the presentation rather than the imitation.
If you prefer to buy flies, I have several different patterns for sale. They are offered in multiples of three, priced at $7.50 for three flies.
For people who would like to experiment with tenkara flies but who do not want to buy a lot of new materials just to try out a particular fly, I have put together a series of "One Fly" Tying Kits™ which contain all the materials required to tie 25 flies of one pattern. If you like the pattern, then you can buy the materials in bulk. If you don't, you can move on to another pattern without having accumulated a lot of stuff you'll never use.
Most of the following flies are ones that I once offered for sale but due to a lack of time I now offer only as step by step instructions to help you in tying your own. For some of the flies there are "One Fly" Tying Kits™. The hooks and materials needed for the others are on the Fly Tying Materials page.
Most of the fish I catch are caught on a Killer Bug. I often wonder why I fish anything else. I have not adopted a "one fly" approach to tenkara and I doubt I ever will. If I did, though, it would almost have to be a Killer Bug (or the Killer Kebari, which is essentially a Killer Bug with hackle; or a Killer Bugger, which is a Killer Bug with a marabou tail). It certainly meets the requirements that Dr. Ishigaki set when he chose to become a "one fly" fisherman: it is simple to tie and it catches fish.
The Killer Kebari is the fly I tied for the first tenkara fly swap held in the US. Although the sakasa kebari is the best known tenkara fly in the US, many of the tenkara flies used in Japan are not reverse hackled. One of the Hida Takayama tenkara flies is just a fairly thick wool body with a soft hackle of hen or hen pheasant. That is about the perfect description of the fly you would get if you added a soft hackle to a killer bug. I've fished hackled killer bugs and have done very well with them.
The Killer Bugger is a cross between a Killer Bug and a Woolly Bugger, basically just a Killer Bug with a marabou tail. The Woolly Bugger has proven itself everywhere, and the Killer Bug has proven itself just about everywhere people have tried it. I'm pretty confident the Killer Bugger will, too.
The simplicity of Dr. Ishigaki's sakasa kebari (reverse hackle) style tenkara fly is very attractive. It requires only two materials and is quick to tie. I don't know what he calls it, but ever since he freely shared the pattern when he came to the US in 2009, everyone has called the pattern an Ishigaki Kebari.
When you consider that most tenkara fishing in Japan is done in high-gradient mountain streams - not unlike many of our wild brookie streams - simple patterns make sense. In small mountain streams, fish do not have the luxury of closely examining their food. It goes by too fast. Fish in those conditions must eat quickly or not at all. If the pattern looks like it even might be food, and if the presentation is good, that's probably enough.
Tenkara USA claims a trademark on the name, even though they did not develop the pattern and the name was in the public sphere ever since Dr. Ishigaki made the recipe and tying instructions public in May of 2009.
The Sakasa Kebari style of fly was developed with attention to presentation in mind. Tied with a reverse hackle, whether a soft hackle or a rooster neck, it pulses when the angler tightens and loosens his line. This gives the fly the impression of life, and can be the most effective presentation you can achieve (and you can achieve it better with a long rod and light line).
Most people think that the fly is shaped the way it is because of that pulsing action. The sparse hackle on a British soft hackle will fold down along the hook shank when it is pulsed, while the sakasa kebari will open up.
I don't think that's the reason. I think it was chosen because if it is tied full rather than sparse it acts like a sea anchor or drogue chute (an underwater parachute). It resists the pull of the line, which reduces line sag. It allows a tenkara angler to keep a light line off the water's surface better. That reduces drag.
Interestingly, Japan is not the only place where you find such flies. In the Sesia valley in northern Italy, flies have been tied with reverse hackles for hundreds of years. And for hundreds of years, fishermen there have used long rods with light lines tied to the rod tip.
Coincidence? I think not.
The Hen and Hound is a sakasa kebari style fly, but to me it is a special one. To some extent it is an outgrowth of Dr. Ishigaki's "one fly" approach, although my take was more of an "any fly" than THE ONE fly. I was in Colorado visiting my sister and decided to tie a few flies with the materials that were at hand: Ginger colored hackles from her hens and a bit of dubbing from her yellow Labrador Retriever. Orange silk thread to hold it all together (that's what was already in the bobbin holder) and a barbless hook - required for Rocky Mountain National Park. I caught fish, and have tied more from time to time. Each time I tie it, the better I like it.
The Little Dark Kebari is actually a closer adaptation of the Hida Takayama style than is the Killer Kebari, which has already proven to be an effective and popular fly. The Little Dark Kebari is a bit smaller and darker, and may be taken by the trout to be a little black stone fly or little black caddis, or any one of the small, dark mayfly nymphs that make up a good percentage of a trout's diet.
My second best fly, for the second (or maybe third) year running, was Hans Weilenmann's CDC & Elk which is an elk hair caddis variation. For where I fish, the CDC & Elk is the only dry fly I feel I need. Fished dead drift or skittered, this fly draws strikes!
Although the Stewart Black Spider is not a Japanese tenkara fly it is an unweighted wet fly, and a generic pattern that does not try to match a specific hatch - one that you could have on your line all the time, as did WC Stewart. The soft hackles also pulse just like those of a Sakasa Kebari. It may not be traditional, but to me it perfectly fits with the simplicity of tenkara.
The Keeper Kebari is a yarn bodied sakasa kebari tied on a size 6 Daiichi 1560 nymph hook. It is a modification of the huge flies Sakakibara san tied for me on my first visit to Japan. Although a larger fly than most tenkara anglers use, it's not too large for trout and not too small
for bass. Sunfish take them easily (and
readily). What was most surprising was how confidently the fish take the fly, with no hesitation. I've had trout in particular hit the fly as soon as it hit the water.
No one would say this is a tenkara fly. Then again, a few years ago no one would have said the Killer Bug is either, yet more than a few tenkara anglers swear by it. The Pink Chenille Worm is a variation of the San Juan worm, tied small and with a small hook. It is very simple, very cheap and very effective, which sounds suspiciously like Dr. Ishigaki's reasoning behind his "one fly."
The Overhand Worm is even simpler than the Pink Chenille Worm. It needs no vise, no tools other than scissors or nippers and no thread. You can tie it while on the stream and it takes only seconds to tie. Best of all, it is an extremely effective fly.
The Yarn Nymph is a simple unweighted nymph for when fish are taking nymphs high in the water column (when you see "rises" but no bugs on the surface and no emergers actually emerging).
I'm a little surprised none of the "one fly" adherents have declared that their one fly is the woolly bugger. It has to be one of the most productive flies ever developed. Often tied large and heavily weighted, a "tenkara woolly bugger" should be relatively small and unweighted. The fly shown here is tied on a size 12 nymph hook, with black marabou, black ostrich herl and a starling feather.
The 60s Rocker Sakasa Kebari is an adaptation of Ashley Valentine's shocking (and shockingly effective) Punk Rock Sakasa Kebari. Named 60s Rocker because it looks a rock star from the 60s whose once luxuriant hair has gone wispy and gray, this is the fly to tie if you're out of purple starling.
The Indicator Kebari is tied to use as a strike indicator. It is tied around the tippet as shown in the photo to the right or with a loop of mono (or silk bead cord) as a "tail" to which tippet to a second fly can be tied. It is a wet fly but it is kept at the surface by fishing with a relatively short, tight line. Bright and highly visible, it will clearly indicate strikes on the point fly while drawing a few strikes itself. And unlike most floating indicators, this one has a hook in it!
A Tenkara Rod with Western Flies works very well. Don't think for a minute that you have to give up what you have used successfully for years. If you are a hatch matcher from way back, you can still match the hatch with a tenkara rod.
Tenkara Flies for Bass? Sure!
In Japan, tenkara is used almost exclusively in mountain streams and almost exclusively for trout. In the US, more and more tenkara anglers are pushing the envelope and using tenkara rods in other waters and for other species. Bass and bluegills immediately come to mind.
Of all the tenkara flies for bass I have used, the best, by far, was a big kebari tied with a wool yarn body and large partridge or pheasant hackle. The fly shown is tied with Nymph Yarn and partridge, although I had equal success with the Black Killer Bugger yarn and hen pheasant breast hackle.
Crane fly larvae get big - up to two or three inches long. The Utah Killer Crane Fly shown here is tied on a size 6 Daiichi 1560, which is a 1 xl hook. Compared to the real thing it is still a bit on the small side, at about an inch. Still, it is a meaty mouthfull meant to tempt a hungry trout.
A size 6 fly with a yarn body, which will absorb water, will get heavy. The one pictured will be even heavier, as it has 10 wraps of lead wire. It really is a bit much for traditional tenkara rods, which after all, were designed to fish unweighted wet flies. For a nontraditional rod, like the Daiwa Kiyose SF series, that isn't a problem.
Elegant flies are simple. Not all simple flies are elegant. The classic Partridge & Orange North Country wet fly is elegant. It is also extremely simple, consisting of nothing more than a silk thread body and a turn or two of partridge hackle. At the other extreme, an Overhand Squirmie - just a piece of Squirmie Wormie tied in an overhand knot around the hook shank - but it is the polar opposite of elegant.
The TenkaraBum Streamer Challenge was to fish with streamers and bucktails. I don't know how many times I have heard (from someone who has never fished with a tenkara rod) that you can't fish streamers. The results from the challenge proved that not only that you can fish streamers with a fixed line rod, you can do so very effectively.
The goal of the TenkaraBum No Vise Challenge was to show that people who don't currently tie their own flies don't have to be intimidated by which vise to buy and what tools are needed. The challenge showed that very effective flies can be tied with nothing more than the clamps and nippers you already have and take to the stream every day. The flies won't win any contests (except for this one!), but the fish are the only judges that matter, and the fish approved.
The Utah Killer Bug Challenge was cosponsored by the Appalachian Tenkara Anglers Facebook Group, Tenkara Guides LLC in Salt Lake City, UT and TenkaraBum.com. Prizes for largest fish, smallest fish, most fish, and most fish species caught with a Utah Killer Bug.
The TenkaraBum Winter Challenge took the "20-20 club" to a new level. Limited to flies size 20 and smaller, anglers got points for the length of the fish in inches plus the size of the hook. Thus, a 20" fish on a size 20 hook scores 40 points, but a 15" fish on a size 32 hook scores 47 points. The challenge was to catch big fish on small flies.
The TenkaraBum Challenge 2014 stemmed from the comment "You can catch anything with a black woolly bugger."
The fly at the center of TenkaraBum Challenge 2014 wasn't a woolly bugger, but a Killer Bugger - which is a cross between a Killer Bug and a Woolly Bugger - basically a Killer Bug with a marabou tail.
The TenkaraBum Challenge 2014 was a species contest. The winner caught 23 species on a Black Killer Bugger, and among all contestants, 53 species of fish were caught.
So, what can YOU catch with a Black Killer Bugger?
The Blue Fly Challenge was a fly tying contest judged by the fish. All that mattered was that the fly was predominantly blue, included at least some of the TenkaraBum Blue Fly Yarn, and most importantly, caught fish! Prizes were awarded for first fish, largest fish (a rainbow trout estimated at 6-7 lbs), smallest fish (an eastern mosquitofish that almost fit on a penny) and most fish.
