Review: Mizuno JPX 925 Forged irons

If you’re looking for some stunning irons, then you don’t need to look past Mizuno. In 2025, that’s especially true, with the JPX 925 Forged range of irons.

The Japanese brand are synonymous with irons that both look the part and crucially, feel and perform to the highest level. But, how do the latest offerings compare?

As you’ll likely know, January is a big month for equipment brands, with plenty of new clubs launching. Mizuno is no different and their JPX 925 Forged irons certainly look great, let’s see how they perform.

The First Look

There’s absolutely no surprises here. If you’re a Mizuno fan, then you’ll love the look of these from the Japanese giant.

I was at a launch event for these irons – amongst some other Mizuno gear – in London last year, and everyone was immediately drawn to the JPX 925 Forged Black irons, which is no surprise when you take a look at them.

They’re the same shape as the JPX 925 Forged irons, and they are both very easy on the eye. From the back, these certainly aren’t busy to look at, while you can see that there’s a good level of technology here, which we’ll get onto.

Behind the ball, these are so clean, without being intimidating. Minimal offset along with a fairly thin topline makes them appealing to decent ball strikers, without alienating amateur golfers.

It’s worth noting that these irons are a continuation from the Mizuno JPX 923 Forged range, which catered well for solid ball strikers looking for good levels of forgiveness. They join a range of 925 Hot Metal irons that will perform well for golfers looking for great distance and forgiveness in their scoring clubs.

The Tech

Let’s take a look at some of the key technologies in the Mizuno JPX 925 Forged range of irons.

CORTech Design

Mizuno fans will be well aware of this technology, which features a Contour Ellipse Face. An advanced multi-thickness face profile optimises ball speed across the whole face, giving impressive ball speed even on mishits. The innovation behind this Contour Ellipse Face required new methods for Mizuno and it certainly looks to have paid off.

Grain Flow Forging

In these irons, Mizuno employs its proprietary Grain Flow Forged HD process. The long irons (4-7) in the JPX 925 Forged series are crafted from Chromoly 4120, a material known for its exceptional strength and malleability, enabling higher ball speeds and easier adjustability. While this still feels great, emphasis is placed on performance, particularly in clubs that are more likely to be mishit.

The shorter irons (8-GW) are forged from 1025E Pure Select Mild Carbon Steel, a material that delivers superior control, precision, and the legendary buttery feel Mizuno players expect. Together, these materials ensure a flawless transition through the set, offering the perfect balance of speed, precision, and feedback.

Triple Cut Sole Design

This is a key part of the design of these irons, which improves turf interaction. The leading edge is gently bevelled for a clean entry into the turf, while a hard-cut trailing edge allows for a smooth exit for superior uninterrupted ball contact.

The bunkered Verdict

I’ve always been a huge fan of Mizuno irons. Before my current set, I had some JPX-850 Forged irons, which I didn’t think I would ever get rid of. So, when Mizuno invited me down to try these, as well as some other products out, it was a blessing.

Like everyone else in Golf Groove, Wimbledon, that day, I was immediately drawn to the black version of these irons. I’m happy to confirm that they perform just as good as they look.

It’s hard to describe the feel of a Mizuno iron but if you’ve hit them, then you know what I mean. They’re buttery, without being so soft that they’re unresponsive from the face. That’s something that Mizuno is unlikely to ever lose and it’s a huge plus point.

Looks wise, these nail it too. In both the regular chrome and black models, they are stunning. Minimal branding on the back makes for top shelf appeal, while behind the ball they are great to look at. A hint of offset, with a thin topline means they really make you feel like a player.

When it comes to performance, I was seeing solid distances with these. I’m never going to be someone who will hit the ball miles, but these are designed to blend distance and control and that certainly shines through in the first few hits with them. I also found that mishits, particularly low on the face, were still solid.

I’m yet to get these out on the course – if you’ve been in Scotland in the last few weeks you’ll understand why – but I’ve no doubt they would be a great addition to the bag. I’m a single figure handicap golfer and would happily game these, and I think anyone up to a high teen index would love to do the same.

Mizuno certainly know how to make irons and that’s not changed in 2025.
