Mizuno, the Japanese equipment manufacturer long renowned for its expertise in the manufacture of irons, has unveiled its new JPX921 Series of irons engineered with one intention – to improve on-course performance for golfers. The series features the use of Chromoly in a full body forged iron for the very first time.
ATLANTA – Mizuno, founded in Osaka, Japan, in 1906, has long held an enviable industry and tour-wide reputation for crafting the very finest irons in the game, offering golfers the ultimate blend of looks, feel and workability.
The JPX Series irons led a resurgence for Mizuno, starting with the JPX900 Tour and more recently the JPX919 Tour, residing in the bag of the back-to-back 2017/2018 US Open and 2018/2019 PGA champion. Now Mizuno has unveiled the next evolution of JPX – the JPX921 Series, a highly engineered family of irons that has been developed alongside Mizuno’s comprehensive custom-fitting program to deliver exceptional performance and help all golfers get the very most from their games.
The new family comprises JPX921 Forged, integrating the power of Chromoly into a full body forged iron for the very first time, JPX921 Tour, JPX921 Hot Metal and Hot Metal Pro, with each model engineered to help enhance performance for particular swing types. The JPX921 Forged offers the fastest ball speeds Mizuno has ever produced from a fully forged iron; JPX921 Tour blends precision with enhanced stability from off-center strikes; the JPX921 Hot Metal and Hot Metal Pro represent the 3rd generation of Mizuno irons to be crafted from high-strength Chromoly 4140M. Despite design differences, all members of the JPX921 family of irons are unmistakably Mizuno in profile and sensation through impact.
“Applying the potential of Chromoly means that the JPX921 irons hold their own in any simulator test – without having to crank #7 iron lofts at all cost. Look, feel, launch, spin and landing angles have to be right through the set. Ultimately what sets Mizuno irons apart,” says David Llewellyn Director of R&D for Mizuno.
JPX921 Forged / Faster, Forged, First
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.
Additional perimeter weighting with toe bias creates a Stability Frame to maximize results from off-center 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.

JPX921 Tour / The Chosen One
The most chosen Mizuno model on the Tour among non-contracted professionals – the JPX900 Tour and JPX919 Tour were both played to win Major Championships. The stunning new JPX921 Tour maintains its predecessor’s surprising fusion of precision with stability from off-center 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-center 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.

JPX921 Hot Metal / Chromoly 4140M
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 utilize 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 center 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-center strikes.
“The introduction of Chromoly was the breakthrough Mizuno needed to take a step up in ball speed. We learn more about the potential of Chromoly with each generation and push it further each time,” says David Llewellyn.
