Pros: The JPX-EZ and JPX-EZ Forged irons pull off a trifecta; they’re distance-oriented irons that offer exceptional forgiveness and better feel than similar irons in their respective categories. 

Cons: They won’t produce the awe-inspiring distance that more compact irons in their classes have accomplished. 

Who’s they’re for? Single-digit handicappers all the way to golfers trying to break the century mark. Mizuno’s new JPX line appeals particularly to those who want more forgiveness and distance than the company’s MP line offers, while still valuing clean looks and a solid, soft feel.

The Review

Can a golf equipment company make an iron that offers maximum forgiveness, big distance and still retains a soft, solid feel? Yes. Well, mostly yes. With the JPX-EZ and EZ Forged, Mizuno places an emphasis on giving players the best feeling, distance-oriented club on the market.

The trouble with distance irons is that while they’re forgiving and engineered to produce a high and towering ball flight, they generally lack in the feel department. Both the JPX-EZ and EZ Forged tap into Mizuno’s heritage, and while no one will confuse them with a Mizuno MP iron, many golfers are going to be taken aback by just how good these feel.

Mizuno JPX EZ iron
JPX-EZ irons use “Power Frame” and “Dual Max COR Pocket Cavity” technologies.

Because there’s less mass directly behind the ball at impact, neither the EZ or EZ Forged felt quite as solid as Mizuno’s MP-5 and MP-25 irons. But it’s still impressive how good both irons felt. If your only metric is “feel,” the JPX line, and the EZ Forged in particular, should be on the top of your list of irons to try in the oversized players irons category. 

Some purists might label this as sacrilege, but in comparing the EZ Forged with the MP 25s (both forged out of 1025 Boron), “pured” shots were often indistinguishable. In fact, several of my mishits with the JPX-EZ and EZ Forged felt significantly less harsh than similar shots with the MP-25s.

Mizuno’s 1025 Boron is 30 percent stronger than the 1025E Carbon Steel used in previous irons.

Forgiveness is achieved by moving as much weight as possible toward the perimeter and away from the center of the club. Mizuno uses PowerFrame technology to stretch weight to the corners of the cavity, effectively enlarging the sweet spot. As long as I made reasonable contact, shots were true, dispersion was excellent and even with KBS C-Taper shafts the stock ball flight was high.

Extreme misses (severely toe side or high on the face) were punished appropriately, but if you can consistently make contact somewhere toward the middle of the face, both clubs will yield acceptable and consistent results. The wider sole on the JPX-EZ irons provides more margin for error and promotes cleaner turf interaction from all lies thanks to its Triple Cut Sole, which made turf interaction a breeze whether I was on the fairway or in the rough. Truly deep rough is not going to be any larger iron’s forte, but the JPX-EX seems wholly above average. 

Mizuno may not make the longest distance-oriented irons on the market, but they are among the most consistent. Compared to the MP-5s and MP 25s, the JPX were both about 0.5 clubs longer. But more importantly, I could hit the same number over and over.

On golf clubs, the color black is very slimming, and the finish gives the EZ and EZ Forged irons a compact appearance that isn’t gaudy.

Chances are, if you’re looking at a Mizuno iron, consistent performance is more important to you than maximum distance. These clubs are plenty long, but the ability to dial in distances — especially on less-than-full swings — gives them a leg up on competitors. Being able to say you carry a 9 iron 155 yards is a nice ego boost, but simply hitting your irons farther doesn’t mean you’re going to score better. That said, being able to hit your irons a consistent distance certainly will.

Mizuno JPX-EZ
The JPX-EZ are much larger than the EZ Forged, and use a cast construction to maximize forgiveness.

As one would expect, I had no problem moving the ball both directions on a mid/high trajectory, however, hitting low cuts and draws were a more arduous task. For most players, the lower center of gravity in the JPX line leads to a higher initial launch angle and increased distance. That’s the only opportunity cost here, which likely doesn’t apply to the target consumer for the JPX line. 

If you’re already a high launch or high spin player, but want more forgiveness, looking at an MP iron — such as the MP-H5 — might be a better choice. If you’re sold on your 6-PW, but looking for an easy to hit, high-launching long iron, don’t discount using either model at the bottom of your lineup.

The numbers: JPX-EZ and JPX-EZ Forged

To test the irons, I hit 10 shots with each club (4, 7, PW) and threw out any anomalies. All clubs were tested with KBS C-Taper Stiff shafts at 0.25 inches over Mizuno standard and measured on a Flightscope X2 Launch Monitor.

Imagine that; the JPX-EZ and EZ Forged had nearly indistinguishable numbers. My results are more likely the exception and not the rule, as I would expect more golfers to get more distance from the larger, cast JPX-EZ irons. So what these results speak to is just how good of an oversized forged iron Mizuno made in the JPX-EZ Forged.

Along with their performance, what really made an impact on me was how good the EZ Forged felt. It’s really the first distance iron from Mizuno that felt anything like an MP iron. Given the similarity in performance, you might be asking, “Does the EZ Forged feel $200 better than the JPX-EZ?”

As a long-time Mizuno player, I’d lean toward an emphatic, “Yes!”

Final Thoughts

Mizuno has never been about making the longest iron on the market — just the one that help golfers score the best. With the JPX-EZ and EZ Forged, the company continues to encroach on new territory by producing irons that target higher-handicap golfers and offer a lot of the game-improvement features this clientele will surely appreciate.

All that, and they wrap it up in a package that looks and feels great.

I didn't grow up playing golf. I wasn't that lucky. But somehow the game found me and I've been smitten ever since. Like many of you, I'm a bit enthusiastic for all things golf and have a spouse which finds this "enthusiasm" borderline ridiculous. I've been told golf requires someone who strives for perfection, but realizes the futility of this approach. You have to love the journey more than the result and relish in frustration and imperfection. As a teacher and coach, I spend my days working with amazing middle school and high school student athletes teaching them to think, dream and hope. And just when they start to feel really good about themselves, I hand them a golf club!

  1. I play the JPX 850 forged, they seem very similar to this EZ forged, same material 1025 steel with boron and from a design point of view they seem to have almost the same features, apart from 850 being in satin steel and the EZ in dark grey colour. My 850s are truely custom build fitted with non standard Nippon Modus 3 120S shafts en MOI matched throughout the whole set incl. my three Vokey wedges. How do these models compare to you? I changed from Titleist 712CB:s wanting something a bit more forgiving and I think I got what I was asking for. More forgivness, about 0,5 club longer, still with a forged feel and consistency. I have a hand full of friends who’s considering a change going in my direction next time. I play of hcp 3, EGA-norm.

  2. Nice review. The new EZ Forged do have a great sound/feel contrary to some of the talk on the forums! As far as the regular EZ’s they look pretty nice in hand for such an oversize design. Much better than previous EZ irons.

  3. Nice review, but can’t help feeling it would have more relevance if the flightscope numbers came from an average Ss golfer. 188 7 iron, really! Some great striking there Sir, I commend you, but surely the average golfer would only hit a 7 iron 150/160 max. Can’t really see the benefit of using tour pro + swing speed models

  4. 137 with a 4 iron is not unreasonable. This is about my ball speed with a 4 iron, with about 97-99mph 4 iron ss. Also, yet’s remember that the loft on this 4 iron is 22*, which is basically a 3 iron. When you combine that with the hotter face of game improvement irons, 137 ball speed is not overly crazy. I think the point is just how much distance can be gained. The the average tour pro carries a 4 iron just over 200 yards (again average, not Rory and Dustin alone), but this tester, with probably a close to tour average ss carries this “4” iron 15-20 yards father. It’s just more ego boost irons to let local 19 handicaps (who should be 24 handicaps) hit their 8 iron (which is really a 6 iron) 150 yards. They realized they’re not going to get any better, but if they can get longer, at least they can feel good about themselves. I don’t see any point to putting number stamps on irons anymore. Why not just put lofts like they do with wedges?

  5. I play the EZ Forged and absolutely love them. Reviewer was correct. Performance is extremely consistent. Literally point and shoot. I adjusted to gap change with no problem. It was unnoticeable.

    • Mike – Thanks for the read. A couple things to keep in mind – I do have a swing speed which is on par with PGA tour averages. That said, it’s easy to focus solely on this facet and miss some very important information. I do all of my testing in Colorado (at 5000 ft) and thus my carry distances tend to be higher than people are probably expecting to see –

      The feel, performance, looks, etc. of the iron are going to be quite similar regardless of ball speed generated.

  6. Nice review. So you are saying that distance wise all four sets of clubs are the same given that the JPX clubs tested are 2 degrees stronger than the MP clubs. However, the JPX lines give extra help getting the ball airborne and as a side benefit hold the line better with the added backspin. It should also be noted that the new JPX lines have the larger 5 degree gaps for 9i, PW and GW compared to the MP lines which still have a 4 degree gap for 9i and PW. This has to be considered when matching these clubs to wedges. Other than the increased lofts near the wedges I like what I read. I’m very consistent with 4 degree gaps for all my irons, so I’m not sure about 5 degree differences in the higher lofts where I need more precision. I’m also concerned about bending the boron as current Mizuno 1025SE is stiff enough compared to older Hogan irons.
