Intro To Daiwa J Braid Fishing Lines

Almost every angler alive knows the Daiwa name to be synonymous with fishing gear. From coast to coast, fishermen turn to Daiwa for their saltwater reels and offshore rods. Offshore anglers are well aware of their 8-carrier J Braid line, as they’ve been using it for years.

Due to popular demand, Daiwa made the later decision to add the 4-carrier J Braid. Though the 8-strand features a smoother profile and the 4-strand is thinner, both use the strength of Dyneema fibers. But that is now changing!

With the new introduction of Daiwa J Braid x8 Grand, Daiwa will no longer be using Dyneema. As the parent company of the polyethylene material, Toyobo will discontinue the Dyneema TradeMark and switch to the IZANAS TM. What does this mean?

You can read about IZANAS for more info, but the x8 Grand offers an improved braided line. The stronger molecular makeup of the new IZANAS material gives more body to the braid. It has a better lay on the reel spool and enhanced abrasion resistance.

Key Features 

Strong Dyneema Or Ultra Abrasion Resistant Izanas Fiber

Whether you opt for the original Daiwa J Braid x4, x8, or the newer Grand, you receive the strength of an ungiving fiber. Daiwa may change over to Izanas fiber for all J Braids in the future. For now, the x4 and the x8 use the high-strength of polyethylene Dyneema fiber.

Splurging for the Daiwa J Braid x8 Grand gives anglers access to a newer, stronger fiber material. Using the same tight weave but with Izanas on the carriers more than doubles the abrasion resistance of the braid. Add 3 points to the development team over at Daiwa!

Tight Weave With 4 Or 8 Strands

Daiwa Uses A Tight Weave On J Braid Lines

Though the 4-strand weave of the Daiwa J Braid x4 has a rougher profile, anglers benefit from its thinner diameter. Especially in higher line tests, the reduction in diameter can add precious yards to your reel spool. Daiwa J Braid x8 or x8 Grand have a smoother profile. The weave has fewer edges and a more circular shape.

Using a tight weave helps to smooth out the profiles of both 4 and 8-strand braids. It uses more material as there are more weaves (pics) per inch. Besides having a smoother profile, tightly woven braids reduce friction on the line guides and have a longer lifespan.

Soft & Supple Untreated Braid

While many anglers prefer the Enhanced Body Technology of Power Pro or the Fluoropolymer Treatment of SpiderWire Stealth, others like a limp feel. Daiwa J Braid goes without a fiber treatment process resulting in a softer supple line. Limp braid can be tougher to tie with, especially when wet. As a general rule, however, it performs better on spinning reels than with baitcasters.

Super Sensitive Non-Elastic Line

Like all quality polyethylene lines, Daiwa J Braid doesn’t stretch. You’ll feel every bite down to the smallest nibbles with J Braid. The strength and sensitivity of braid don’t come without drawbacks. Be certain to tune in your drag or suffer the fate of pulled hooks. Watch out for nasty under wraps on your conventional reel and practice your casting.

Pros & Cons Of Daiwa J Braid


The Daiwa J Braid series offers affordability in comparison to many name brand lines. With almost no memory, J Braid lines perform best on the spools of spinning reels. That limp quality holds better on an upright spool and isn’t as prone to forming wind knots.

Though braided fishing lines that use a treatment process are slicker and better for inline casting, Daiwa J Braid is still a quality product. All three offerings in the series use high-quality materials and a superior design. Their tight-knit weaves offer more pics per inch, adding to durability and reducing abrasion.


That same limp characteristic that lends itself perfectly to spinning reels isn’t preferable for use with inline reels. Treated braids tend to offer a touch of memory, which can aid in casting and reduce bird’s nests. Daiwa makes no mention of any color lock technology and the new line may bleed. A good soak before use may be in order if this is the case. Line digging can also be more of an issue with untreated braids.

Best Uses / Fishing Applications

As mentioned, the best use for Daiwa J Braid is on a spinning reel. It’s not a bad idea to use it for filler with monofilament on top. Besides the reel considerations, any choice in the series follows the main attributes of braided line. They offer strength with a smaller diameter that leads to more line on the spool. If you fish open water conditions, extra length sure helps.

As with other quality braids, the series of J Braid lines are ultra sensitive and abrasion resistant. If you cut through growth, the added molecular strength of Izanas fiber makes Daiwa J Braid x8 Grand an excellent choice. J Braid lines are also quiet and cast without a noisy disturbance.

Daiwa Customer Service

Though Daiwa doesn’t extend the same warranty on their braids that they do on their rods and reels, they do offer superb customer service. You can find your nearest Authorized Warranty Center on their website along with their mailing addresses and phone numbers. Their technicians are happy to field questions or help in any way possible.

Tying Up The J Braid Review

85 out of 100 anglers approve of J Braid x4

Each Daiwa J Braid gets its own score according to its useful application, cost, performance, and durability. The thinner x4 J Braid works well for lighter fresh or inshore saltwater applications. Offshore anglers might use it for extra length in backing due to its thin diameter. Daiwa J Braid x8 scores higher with its smoother profile, and the x8 Grand scores highest. Its superior abrasion resistance seals the deal.

    Hello, so… if I’m reading this correctly, I shouldn’t be using the J-Braid on my Daiwa Bait casting Reels? I have 4 Tatula’s of different varieties. Please inform me as to which line I should go with. I fish primarily Lake St Clair in Michigan for Bass. I’m patiently awaiting your response. Thanks for Listening, Daniel J Scheppman

    1. Hello Daniel. I wouldn’t say you shouldn’t be using the J braid on your baitcasters. More that the thin suppleness of the line lends itself better to spinning reels. You can use it as a backing on your baitcasters or fill up your spool with it. But a bad backlash can be impossible to clear, so be careful while casting.

  2. Aaron LeGath

    I use both J braid and J braid grand on my bait casters. It’s my favorite braid for them. I really like the 30# test, any smaller and it tends to get knots and becomes a problem. I switched a buddy over to it as well. He was a mono only guy and he says he’s never going back because of the casting distance and the feel is unmatched. We fish in mostly brackish water targeting red drum, speckled trout, and flounder.

    1. Sounds like you found the perfect match for your baitcasters with the conditions you fish. I yet to move from 15 pound PLine when fishing our local lagoons. Using the J braid for my lighter setups is next on my list.
