Shimano Keiryu Tenkara
34-38 ZL

The Shimano Keiryu (Mountain Stream) Tenkara 34-38 ZL is a 3.4-3.8 meter zoom tenkara rod. It very nicely fills the niche left empty when Daiwa discontinued the Sagiri 39MC, which proved to be a very nice length (or rather lengths) for tenkara.

Over two years in development, the rod breaks some new ground. The most obvious is the use of EVA foam for most of the grip. The front inch and a half or so of the grip is cork, but the rest is very nicely shaped foam. One of the first American tenkara anglers to fish it pronounced it "freaking awesome."

The foam grip is really very nice. It is not "squishy" at all and is probably the type of grip we will see on the majority of tenkara rods in the future. Face it, even bad cork is expensive. Much better to put those yen into the blank rather than the grip.

After "carpet casting" one at the Somerset Fly Show just after it was introduced, I pronounced this a "Wow" rod (in fact I did - out loud - after the first few casts). It is very light and has tremendous damping.

When I first wrote this page, I described the rod as "crisp," thinking of the damping. One of the first buyers questioned that description, saying he felt the rod was way too soft to be called crisp.

The rod does not feel overly soft when you cast it with a light line (at least to me it doesn't). I have heard that it was designed for a 3.5 line but I have to say I prefer to use a size 3 with the rod at full extension. At the shorter of the two lengths, a 3.5 line is an excellent choice. (You could certainly use the 3.5 line at both lengths, though).

Perhaps the most surprising aspect about the rod is that it is firmer at the shorter length than it is at the longer length.

That is unlike any other zoom rod I know of, and is unlike nearly all other rods that come in two or more different lengths. Normally, the longer length is firmer (has a higher penny rating) because the only difference between most 330 rods and their 360 counterparts is the addition of one more section. Since the added section is one of the thicker, stiffer ones near the grip, the longer rod feels stiffer.

The more you think about it, though, the more the Shimano Keiru Tenkara 34-38 design makes sense. Many anglers, particularly in Japan, prefer a slightly firmer rod for fishing smaller, tighter streams. It's not about fish size - it's about casting precision. They are trying to hit smaller targets and find that a slightly firmer rod, generating slightly higher line speed, gives more accuracy. On larger streams, pinpoint accuracy is not as critical, and the silky smooth casting stroke of a softer rod is more highly valued. Every rod is a compromise, and you might give different features different weights depending on where the rod will be used.

At the shorter 11' length, the Shimano Keiru Tenkara 34-38ZL is a 19 penny rod - the same as the Shimano LLS33NX - their premium small stream rod. At full extension, though, it is a 14 penny rod - the same as the Nissin Zerosum 360 6:4 and just a penny less than the Daiwa Enshou LL36SF, which are two of nicest level line rods there are.

Just as the rod design was dialed in for Japanese tenkara anglers' rod preferences relative to stream size, it was also dialed in for fly choice. The rod just excels with an unweighted kebari (and does quite nicely with a CDC & Elk). I have a customer who mostly fishes soft hackles and flymphs, and he loves it. This is not a rod that you would want to use with heavy nymphs, though. You could fish a size 18 or 20 bead head nymph, but it is not a rod for size 10 tungsten and lead stonefly nymphs by any means.

I would have to say the rod is also dialed in with fish size. The largest fish I've caught with the rod is a smallmouth bass that was probably a bit shy of 12". That's about as big a fish as I'd target with the rod. You certainly could go a bit bigger with trout, assuming you were not fishing in heavy current. In Japan a 12" fish is a trophy, though. You'll land the fish, but you'll remember the fight for a long time.

Please note: My automatic shipping calculation is not working properly for international purchases. Any package over $400 OR over 24" long must go via Priority Mail International. The calculation is working properly for value, but not for length. Some long packages that must go via the higher Priority Mail rate are being charged the lower First Class rate. If that happens for your purchase, I will send an invoice for the balance. I am not trying to make a profit on shipping, but I do need to cover the cost that the USPS actually charges. If you receive an invoice for additional shipping, the invoice must be paid before the package will be shipped.

I apologize for the inconvenience.

...fished at two lengths and cast like magic.

The Shimano ZL is a cool rod. I really like it.

John V, Utah

This rod is an amazing chunk of graphite. Love the grip.... truly accomodating. Tried 2.5, 3, 3.5, and 4 lines. Today 3.5 was the one but all worked. No thought or effort needed for the 3.5...the rod worked by itself.

Stephen M, Massachusetts

Still place this rod as my favorite Tenkara rod. I have many rods for different uses. When it comes to the one rod that puts the biggest smile on my face it is my Shimano ZL. Just a smooth casting accurate rod that allows me to dissect a piece of water. Fish on feel is amazing with this rod and every head shake is registered. Hard rod to come by, but well worth it IMO.

Jeff R, Texas

After getting used to the smooth rhythm of this rod's action I could put the fly anywhere I wanted without difficulty. The rod casts effortlessly and is very, very smooth with a #3.5 level line.
