Mizuno’s new JPX923 irons are engineered for total performance and feature five unique models created from three specific metals, based on Swing DNA data from over 350,000 golfers. This creates options for elite tour players, slow swinging amateurs and every player in between.

The JPX923 Tour, Forged, Hot Metal, Hot Metal Pro and Hot Metal HL all come with a white-satin brush chrome-plated finish which is non-reflective.

JPX923 Tour
Consistently Mizuno’s most-played iron model in professional golf and still one-piece Grain Flow Forged in Hiroshima, the JPX923 Tour adds a copper underlay for an even smoother sensation at impact comapred to the JPX921.

The JPX923 Tour also presents a narrower top line and sole in tandem with more rounded trailing edge for cleaner turf interaction. Player enhancements made possible through the introduction of Mizuno’s new ‘V-Chassis’.

One-piece Grain Flow Forged HD: Forged from 1025E Pure Select mild carbon steel at Mizuno's iconic facility in Hiroshima, Japan, where Mizuno irons have been produced since 1968.
Soft copper underlay: A microlayer of copper between the base Nickel and outer Chrome for legendary feel. Made famous in the iconic TN87.
New V-Chassis, thinner topline: Engineered via Mizuno’s ‘Harmonic Impact Technology’ project to create ‘muscleback’ type vibrations and feel from a cavity design. Prior models required a slightly thicker topline to maintain feel.
Cleaner turf Interaction: A generously rolled trailing edge enables versatility and immaculate turf interaction.
Refined scoring irons: Noticeably shorter blade length and more compact from 6 iron to GW for precision where most needed.

JPX923 Forged
A mid-sized, full body Grain Flow Forged iron delivering optimal balance of ball speed, stability, and feel.

Mizuno's third generation of Chromoly Forging (4-7 iron) incorporates a milling slot that extends wider to heel and toe. Paired with an even thinner clubface, it creates the brand's highest one-piece forged ball speeds from an even greater portion of the clubface.

The irons showcase a thinner top line throughout, plus compact scoring irons (8-GW) and bevelled sole for improved turf interaction.

Grain Flow Forged: For Mizuno's unique, soft feel, at Mizuno's facility in Hiroshima, Japan.
New V-Chassis, thinner topline: Mizuno’s ‘Harmonic Impact Technology’ creates a dense, more satisfying feel at impact. Prior models needed a slightly thicker topline.
3rd Gen Forged Chromoly with wider Microslot (4-7 iron): Forged from a single billet of 4120 Chromoly and back milled from to heel and toe, resulting in extreme ball speeds from a compact workable profile. Face thickness is reduced to just 2.2 mm behind impact (vs 2.6mm in the JPX921 Forged) .
1025E Pure Select Mild Carbon Steel (8-GW): For ultimate precision, and control, and feel in the scoring zone.
Mre Bevelled Trail  Edge: Additional bevelling to the trailing edge for immaculate turf interaction.
Refined Scoring Irons: Noticeably shorter blade length and more compact from 7 iron to GW, for precision where most needed.

JPX923 Hot Metal

JPX923 Hot Metal / Hotel Metal Pro / Hot Metal HL
Hailed as Mizuno's 'fastest-flying and fastest-stopping irons, the JPX923 Hot Metal uses Nickel Chromoly, a new material with help generate additional ball speed.

At 35% stronger than the original Hot Metal material, 4335 Nickel Chromoly enables a high-energy 8% thinner clubface. Combined with Mizuno’s vibration controlling V-Chassis and deep CG design, the JPX923 Hot Metal irons are as enjoyable and controllable as they are long.

Faster Nickel Chromoly: New 4335 Nickel Chromoly is 35% stronger than the original Chromoly, for an 8% thinner, high ball speed clubface.
New V-Chassis: Delivers a more solid satisfying vibration pattern, even though the clubface is 8% thinner.
Increased Stopping Power: Seamless cup face construction delivers the deep CG needed for a high launch and controllable landing angle.
Consistent ball speeds across the face: The thinnest part of the sole is extended 18% wider, creating a wider high-energy area.

JPX923 Hot Metal Pro

Studying over 175,000 recorded Swing DNA fitting sessions with real golfers each year, Mizuno’s R&D team highlighted the need for three distinct player needs and launch patterns, resulting in three Hot Metal models - the Hot Metal, Hot Metal Pro and Hot Metal HL.
