Mizuno launches new Mizuno JPX923 irons

Mizuno‘s new JPX923 irons have been designed to help all golfers maximise their game, particularly amateur players with moderate or slower swing speeds – and there’s a new hybrid, too.

The new irons have five different models, and Mizuno has increased the bounce of all of them, and also introduced a more lofted, high launch model. These developments are to specifically benefit lower swing speed players.


The JPX923 Hot Metal models are in shops now, while the Tour and Forged versions will arrive in February 2023. There’s also a new hybrid to help players who prefer this club to a longer iron, which many amateur players find tricky to hit.

JPX923 Tour

This is a shallow cavity back iron aimed at elite amateurs and pro players. It’s Mizuno’s most-played iron model in professional golf. It’s a one-piece iron forged from 1025E mild carbon steel, and has a new copper underlay for an even smoother sensation at impact. RRP £185 per club.

JPX923 Forged


A mid-sized grain flow forged cavity iron that’s aimed at pro to low and mid-handicappers. It mostly delivers distance, but also a blend of ball speed, stability and feel. The 4-7 irons are forged from a single billet of Mizuno’s third-generation, springy 4120 chromoly steel. For extra feel and precision in the scoring irons, the 8-GW are forged from 1025E mild carbon steel, same as the JPX923 Tour. RRP £185 per club.

JPX923 Hot Metal Pro

The JPX Hot Metal family targets mid to high-handicap players. All three models have a larger profile with additional hosel offset and wider soles. All three are cast, not forged like the Tour and Forged, which makes them cheaper. All are made from Mizuno’s new nickel chromoly, which is 35 percent stronger than the original Hot Metal. Mizuno say its both strong and springy and allows engineers to reduce face thickness by 8 percent.

The Pro is a players’ speed cavity iron for mid handicappers with moderate swing speeds and provides high launch with good stopping power and ball speed. RRP £150 per club.

JPX923 Hot Metal

Hot Metal

This is a forgiving speed cavity iron for mid to high handicappers and slower swing speeds who want straight flight and distance. RRP £135 per club.

JPX923 Hot Metal HL

The HL is a high launch version for mid to high handicappers with slower swing speeds, and for those with an aggressive shaft lean. RRP £135 per club.

JPX 923 Fli-Hi Hybrid


To replace your long irons, which can be difficult to hit for average players. Available in 4, 5, 6 and 7 with 20, 23, 26 and 29 degrees of loft respectively, providing reliable distance gaps between clubs, just as long irons would. They can be included within a custom iron set, with the same shafts.

Weight is located internally on the back to encourage a draw bias as well as a higher launch. A 17-4 stainless steel face and 431 SS body deliver an upgrade in ball speed, and the bendable hosel allows for adjustments in lie angle. The Fli-Hi’s wider footprint and material construction deliver a playable, high-flying hybrid. RRP £150 per club.
