Mizuno JPX EZ Iron Review

Mizuno JPX EZ Irons (1)

50 Words or Less

The Mizuno JPX-EZ is Mizuno’s version of super game improvement irons.  Looks and feel will disappoint “old school” Mizuno players, but the performance is undeniable.


For most golfers, the name “Mizuno” conjures up thoughts of beautiful forged blades with buttery soft feel.  While Mizuno does still make irons in that mold, they’ve been trying to broaden their appeal over the last few seasons with the JPX line.  Their latest offering, the JPX-EZ, boasts “the largest sweet spot in golf.”  Is this truly a Mizuno for the weekend warrior?  Let’s find out.

This isn’t your daddy’s Mizuno.  Whether that’s a good thing or not is going to be a matter of personal taste.
The JPX-EZ is B-I-G, BIG, like, PING G-series big.  Thick top line, huge sole, and lots and lots of offset.  Like I said, it’s not your daddy’s Mizuno.
Beyond the size, the Halloween color scheme is…unique.  It certainly makes the club stand out a bit, but it’s not the kind of thing you’d expect from Mizuno.  In the past, even Mizuno’s game improvement clubs have stuck to the traditional black and blue color scheme.  Ultimately, cavity decorations shouldn’t determine what clubs you buy, so it’s not a deal breaker whether you like it or not.

Sound & Feel

Having been a Mizuno player for many years in the past, I have a pretty strong notion of what a Mizuno iron should feel like: soft, buttery feel on center with pin point feedback.  The JPX-EZ isn’t that.  These irons produce a fairly firm, fairly loud “click” at impact.  In keeping with the game improvement theme, they also cover up the majority of the feedback.  As always, this is a two-way street: there’s no sting in your hands or damage to your confidence when you miss, but there’s also not a clear signal that says, “Stop doing that.”

Let’s start with the headline claim, “the largest sweet spot in golf.”  Mizuno’s website goes so far as to call out specific irons from other OEMs and state exactly how much larger their sweet spot is (check that out HERE).  Does this “larger sweet spot” (a term Mizuno does define, they say it’s based on MOI) translate to being easier to hit?  While I can’t say that it’s noticeably more forgiving than, say, a PING Karsten iron or the TaylorMade SpeedBlades, it is clearly in that discussion.  The bottom line is this: if you can’t hit the Mizuno JPX-EZ, you should switch sports.
Beyond being easy to hit, the JPX-EZ is stupid long.  I wasn’t really expecting this because the lofts aren’t super strong (at least compared to other SGI irons), and it doesn’t have any “visible technology”.  All the same, the JPX-EZ puts the ball out there with some of the longest irons of the year.
All in all, the Mizuno JPX-EZ does everything a super game improvement iron should: it makes golf easier and more fun.  When you take these to the course, you feel like you can aim at flag sticks without any concern for hazards or high scores.

Mizuno may be one of the last names you think of when you think “super game improvement,” but the JPX EZ irons seek to change that.  They are as easy to hit as this year’s most forgiving irons and just as long as the irons with mouthfuls of visible technology.  While they lack the feel and aesthetic appeal of the classic Mizunos, there’s no doubt that these clubs will make the game more fun for a lot of recreational players.

Price & Specs

The Mizuno JPX EZ iron set retails for $700 for an 8 club set.

The stock shaft options are the True Temper XP 105 (steel) or the Fujikura Orochi (graphite).

  1. Hi Matt,

    Watched both of your videos regarding Ping Karsten and Mizuno EZ and seems that you give a pretty nice review of both, so I really didn’t get which irons would be best for a senior high handicapper like me. Can you suggest?

      They’re both good sets. The best answer is to try them both and get a fitting to see which set performs best for you.
      Failing that, I would say the biggest difference is the hybrids: the Karsten set has hybrids, the JPX-EZ is just irons. If you like hybrids, go with the PINGS, if you don’t, opt for Mizuno.



  2. Just bought set of jpx-ez irons. Can’t use them at all. Hard to hit and inconsistent distance. Showed I was hitting 7 iron 145 yards on monitor at golf box, but can’t get 130 yards on the course. Very disappointed in them, will probably sell at big lose$. went back to rocket blades.

    Same thing happened to me. On the launch monitor I was hitting the 7 iron over 150 yards. Played 4 rounds with the Mizuno JPX EZ’s and can hardly get 130 out of the 7 iron.

    I was using Callaway Razr-X HL and recently switched to the JPX EZ’s. I easily hit these 10 yds. more and much more consistency in straight ball flight. Absolutely love these super game improvement clubs.

    Hi Matt,
    I am searching for a new set of irons. My actual hcp is -18 and my actual clubs are Wilson Di7 with steel shafts. I have usually no problem with the distance but more with dispersion. Therefore I am searching for a set of clubs that can help me reduce dispersion. Do you think the JPX EZ could be the right one for me.

    • Matt Saternus


      Good question.
      First, most dispersion problems are caused by not controlling the club face and no club can help that. That said, it will be easier to control a well-fit club (and shaft) than a poorly fit one.
      Second, curvature problems are largely the result of an extreme club path. Again, no club can fix it, but a good fit can help iron out the extremes a bit.
      Finally, what a club can help with is mishits. Hitting the ball on the heel or toe contributes to bad dispersion so a club with higher MOI (what most people call “more forgiving”) will minimize the penalty you pay for a mishit. The JPX EZ claims to be as forgiving as anything, or at least that was the claim when it was new. I would agree that it’s in the conversation with the PING G30 and maybe the Callaway Big Bertha for most forgiving.
      Short answer: get fit by a qualified club fitter. Try everything. Buy what produces the best results.



  6. If you are only hitting the JPX ez 7 iron 130, I’d say that’s a personal problem and not a problem with the club. I own a set of JPZ ez’s and love them. As a matter of fact I holed out from 195 yards for eagle using a 6 iron. To each their own. But, the JPX ez set is a good set and I enjoy using them week in and week out.
