Mizuno, which has set the golden standard for players irons over the years, is blurring the lines between a blade iron and a forged cavity back with its new JPX-900 Tour irons. The new irons pass the eye-test for a blade, but they’re pumped up with performance features usually reserved for Mizuno’s bulkier JPX irons.
A Mizuno JPX-900 Tour 6 iron at address.
Like Mizuno’s MP iron models, which are designed for the most discerning and skilled golfers, the JPX-900 Tour irons are made from Mizuno’s Grain Flow forged 1025E Mild Carbon Steel to give golfers the familiar soft, solid feel for which Mizuno is known.
“We wanted to make the best Grain Flow Forged iron ever,” says David Llewellyn, Mizuno’s Director of R&D.
What’s different about the JPX-900 Tour irons is the more aggressive styling, which is part form, part function. The addition of Mizuno’s angular “Power Frame” to the cavity increases moment of inertia (MOI), which makes the irons more forgiving. Yet according to Llewellyn, the refined cavity-back irons should be an easy transition for its staff players, Chris Wood and Luke Donald, who currently use the company’s MP-5 blade irons.
Mizuno’s MP-64 irons, a forged cavity-back that many in the Mizuno community believe to be the best-feeling Mizuno iron in recent memory, was used as the benchmark for the acoustics of the JPX-900 Tour irons. By using the company’s HIT (Harmonic Impact Technology) system, which measures and quantifies sound frequencies, Mizuno was able to mimic the acoustics of the MP-64 irons while improving on their construction.
Specs
In terms of looks, the JPX-900 Tour irons are smaller than the MP-25 irons released in 2015, with a lower toe height and a “more modern design” than the MP-25 irons, Llewellyn says. Another note of distinction: the soles of the JPX-900 Tour irons which are thinnest ever used on a JPX model, and feature the same sole geometries Mizuno has been giving its MP irons for several generations. This design will create more versatility than ever from a JPX offering, something better players will surely appreciate.
The stock shaft for the JPX-900 Tour irons is True Temper’s Dynamic Gold AMT, which uses an ascending weight design to improve performance of each iron. In the X100 flex, for example, the 3-iron shaft weighs roughly 115 grams, while the pitching wedge shafts weighs about 130 grams. The lighter long-iron shafts help golfers hit higher-flying long-iron shots, making it easier to hit and hold greens, while the heavier short iron shafts provide added stability for greater precision.
Mizuno’s JPX-900 Tour irons, available Sept. 16, will sell for $1,199.99 in either steel or graphite. There is no upcharge for custom shafts or grips.

I use to play Mizuno blades for the longest time 14’s, 29’s and even the 33’s. Didn’t like the 32’s, but these look like they might be that perfect go between blade and cb. If they feel like my old time dizzy blades with a little extra punch Mizuno may have me back. But for now I’m sticking with my King Cobra pro mb/cb’s. Definitely can’t wait to demo. Love the minimal offset, one thing I din’t like about the 29’s in the scoring clubs was the huge amount of offset thus the Tiger combo of 29’s in long irons and 14’s in scoring clubs.

I am using Mizuno TP9s with DG S400 shafts for the last four years (designed in 1986). I bought them from someone who had only used them four times from new (they were still in the original Mizuno box!). I find them well balanced and accurate and they look fantastic. The loft of the 7 iron is 37 degrees. Does anyone have any thoughts as to how they compare with MPs and JPXs should I want to change to a modern club?

Does anyone else see the Ping s55 when you look at these irons? The toe portion of the cavity is identical as well as the general shape of the cavity. Overall design goal is exactly what the s55 achieved: smaller, players cavity back iron. Good news for all the fans of Ping’s S line who have being asking Ping to forge their clubs.

Just the high toe weighting. Everything else is very different, including the unseen tech.

To bad Mizuno doesn’t offer the Dynamic Gold Tour Issue shafts in custom. That’s my favorite iron shaft. These irons would be awesome paired with those shafts. Most of the club manufacturers carry that shaft but for some reason Mizuno does not.

Not this again.
There is no need for those shafts. Mizuno can build their clubs to precise spec with the standard ones. No need to spend the extra money for labels
Dane
Aug 14, 2016 at 1:51 am
It’s not just labels. The Tour Issue model has a tighter tolerance and are more consistent compared to the standard shafts. I can feel the difference between the two and others can agree with me. It’s the #1 shaft model on Tour. Titleist, TaylorMade, Callaway and Ping offer that shaft but not Mizuno. That’s unfortunate in my honest opinion.
Also, Go to TrueTemper.com where they have a video explaining the differences between the two shafts. Your not paying more for a label, your paying more for a better, tighter tolerance and more consistent shaft.

….and everyone on tour was ALSO SST Pured….every shaft can be found to have a most stable plane to install in the head for optimum feel & performance.
while it’s been illegal to manufacture a shaft specifically with a ‘spine’ to be inserted in a specific orientation, It’s not illegal to ‘find’ it in a shaft and reinstall it so it lies on a better axis…
I’m diggin KBS now after being an original Brunswick Rifle defector from DG X100’s

From what I remember originally they’re the same shaft, just cherry-picked. There wouldn’t be any difference in feel or performance between two shafts weighted the same, with the same playing characteristics. The only difference would be the label and the upcharge.
An expert clubmaker could cherry pick the same exact Dynamic Gold shafts off the rack and there would be no difference, apart from the price. You’re only paying more for True Temper to sort the shafts correctly, which is arguably something they should do in the first place.

Some players won’t feel the difference between the standard shafts versus Tour Issue shafts but good players will. Plus the Tour Issue shafts look better with the Tour Issue shaft band.
Christopher
Aug 17, 2016 at 4:10 pm
They’re the same shaft, so they’re imagining a difference. The only difference is that each shaft will match your other shafts in your irons to a tighter margin, but you could cherry pick the standard Dynamic Gold shafts to achieve the same result. Imagine if you bought new pool balls for your 9-ball table, one or two balls are slightly heavier or lighter than the others, that would be your Dynamic Gold set, and the Tour Issue’s would all be same weight. They’re the same balls, they just have tighter quality control with the Tour Issues.

“…should be an easy transition for its staff players.” Highly doubt LD would move from the MP-5 to a JPX iron. Going to be awhile before anything surpasses the MP-5. Looking forward to the JPX 900 driver though, which I think is the most interesting club of the new JPX line.

I think they look very different for Mizuno in a good way. Really looks like the engineers spent their time on this one. A true leap in the generation of their products. I don’t care what they call them as long as they perform.

I have never owned a set of Mizuno irons but have always wanted to . Just never got around to it. I have some Wilson FG Tour V2s with some Nippon shafts that I just can’t kick out of the bag. These look really nice I never liked the looks of the 800 series and didn’t think the MPs were right for me. The MP-64s are beautiful and I was thinking about getting a used set for fun and to try them out. Maybe I’ll have to look into these. This is the first series of JPX irons that look good to me funny I always thought MPs were some of the best looking irons out there and JPX the worst . Hope to see some reviews soon. Maybe Mizuno will want some WRX testers.

While the “no upcharge” is nice, if you prefer a more stock shaft – DG S300 – kind of have to feel you are getting hosed.

Actually, it was a huge, smart move from Callaway…First year of Apex irons, they knew they were so good – and 1099 – $100 more than other big OEM’s ‘BEST’ they offered whichever shaft you needed for no upcharge. That helped make them a huge successs.
When Rocketblades died a painful death after only 8 months and Speedblades (the next ‘greatest iron ever made’) came out with the same POS $9.00 shaft as Rocketblades for $899, getting into Apex (a FAR better head) w/KBS C-Tapers or Project X’s for 200 more wasn’t that big a stretch for shoppers.
it’s a smart move for every OEM. Cripes – even Adams put CTapers in that funky black head a couple years ago, and they came to market for 699. It destroyed that dog Speedblade head…
DG’s are reliable shafts – the standard we judge from – kinda like an IBM Mainframe – but if for no extra charge, you can
definitely get a better feeling better performing stick.
it always goes back to getting fit by an expert – with outdoor ball flight & proper launch monitor… Steel shaft tech has been blowin’ up big time in last 5 years. Take advantage of it!

1. So no tungsten in the soles or the toes? Do they accomplish most of what is going on with the tungsten inserts in other brands, with just the shape of the perimeter weighting? I’d be fine with that. My gripe with the tungsten-weighted Titleists was that the head was just a shade too compact for my own tastes.
2. Are these the strongest lofts that Mizuno has ever offered?
3. I would want a lot more information on the sole grinds. Does Mizuno offer anything custom in that regard? Can you order a blunted leading edge?
4. So is this the prelude to a new MP model?
Brian
Aug 11, 2016 at 12:55 pm
1. Mizuno has never used tungsten inserts in their irons and these do not depart from that standard.
2. These have the same loft specs as the MP-25, MP-15, and MP-5; so no, these aren’t lofted strong.
3. You would likely have to order custom sole grinds from Mizuno’s Yoro arm and should expect to pay a premium to do so.
4. No idea

And, they are also still 1/4″ shorter than Titleist
kloyd0306
Aug 12, 2016 at 8:57 pm
Don’t you mean that Titleist are 1/4 inch longer than Mizuno?
There is no industry standard for length. Who is to say that Titleist’s lengths are the correct length? Besides, stock lengths are only for stock clubs and if you are buying stock clubs from anyone, you may as well drive a car that does not have an adjustable seat, an adjustable steering wheel or adjustable mirrors.
Mizuno measures length WITHOUT the grip. Titleist measures length WITH the grip. There is still a small difference but not a 1/4 inch when both are finished.

If they are in fact smaller than the MP25s then I’ll be salivating over these. May have to work up a combo set with MP25 4 and 5 irons
