The JPX921 Forged iron integrates the power of Chromoly into a full body Forged iron for the very first time. Initially applied in Mizuno’s Hot Metal irons – Chromoly has made the cross over to Mizuno’s forgings with staggering results. Testing shows the fastest ball speeds Mizuno has ever produced from a fully Forged iron.
Grain Flow Forged HD in Mizuno’s legendary facility in Hiroshima Japan, the JPX921 Forged irons offer an identifiable and unsurpassed Mizuno feel. The integration of Chromoly 4120 allows for a clubface up to 0.5mm thinner which delivers the fastest ball speeds Mizuno has ever produced from a full body Forged iron (4-7). A shorter blade length throughout, bevelled training edge and reduced offset gets noticeably sleeker through the set and flows into precision 1025E Pure Select mild carbon steel scoring irons (8-GW).
Additional perimeter weighting with toe bias creates a Stability Frame to maximise results from off-centre strikes, while a 6.4% wider CNC back milled slot further increases stability.
Despite this, the JPX921 Forged irons offer a sleeker, compact profile – a shorter blade length throughout, a beveled training edge and reduced offset. The feel is that of a traditional forged iron as the JPX921 Forged gets noticeably sleeker through the set.

MIZUNO JPX921 Tour
The stunning new JPX921 Tour maintains its predecessor’s surprising fusion of precision with stability from off-centre strikes. Now even thicker behind impact for an enhanced, softer feel with tour refined short irons for smoother turf interaction.
Grain Flow Forged HD from 1025E Pure Select Mild Carbon steel, the JPX921 Tour delivers an identifiable and unsurpassed Mizuno feel. In addition, Mizuno’s Stability Frame with toe bias weighting promotes a longer, straighter and more consistent ball flight, even on off-centre strikes.
The shorter irons feature a narrower sole for improved turf interaction while a thicker cavity pad throughout the set, evolving from Mizuno’s study of vibration patterns, produces a harmonic impact that can be felt for a fraction longer.
With a pearl brush, anti-glare finish to minimize distractions over the ball, the JPX921 Tour offers the sharper, stripped-back functional look that the modern player appreciates.

MIZUNO JPX921 Hot Metal
The JPX921 Hot Metal irons deliver Mizuno’s fastest ever ball speeds, a piercingly straight ball flight together with controllable landing angles. The JPX921 Hot Metal represent the 3rd generation of Mizuno irons to utilise the resilience of Chromoly – R&D generally accepts that any new technology needs three generations to reach near-optimal performance.
The JPX921 features Mizuno’s most complex face geometry to date, to produce additional energy from the clubface; the Hot Metal Pro version offering a more compact profile with reduced offset.
The use of Chromoly 4140M and a re-engineered CORTECH face, now 0.2mm thinner across the centre point, creates exceptional ball speeds. These are further enhanced by the Seamless Cup Face featuring a variable thickness sole design that allows the leading edge to act as a hinge, generating greater flex.
Three additional sound ribs produce a more solid sensation at impact while extreme perimeter weighting and toe bias in Mizuno’s Stability Frame help to deliver greater consistency from off-centre strikes.
