Consistently Mizuno's most chosen 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-centre strikes. Now even thicker behind impact for an enhanced, softer feel, with tour refined short irons for smoother turf interaction. Grain Flow Forged in Hiroshima Japan.
"The longer-term Mizuno professionals tend to play our MP irons - but younger players coming from other brands seem to prefer the stripped-back functionality of the JPX Tour. There's a sharper look and straighter flight that lends itself to the way they interpret the game."
Mizuno’s Stability Frame with toe bias weighting, gives the longer CG distance needed for a straighter, consistent ball flight.

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 a Mizuno's forgings with staggering results. The fastest ball speeds Mizuno has ever produced from a fully Forged iron - a treat for both the senses and the scorecard. Grain Flow Forged in Hiroshima Japan.
Despite the all the tech, the JPX921 FORGED gets noticeably sleeker through the set and flows into precision 1025E Pure Select mild carbon steel scoring irons (8-GW).
A wider back milled slot increases stability from off centre strikes – from a smaller clubhead.
Chromoly 4120 allows a clubface upto 0.5mm thinner for our fastest peak and average ball speeds from a full body Forged iron (4-7 iron).
Additional perimeter weighting with toe bias for stability from off centre strikes.
The JPX921 Hot Metal irons pair Mizuno's fastest ever ball speeds with a piercingly straight, ball flight and controllable landing angles.
The 3rd generation of Mizuno irons to utilize the resilience of Chromoly - the JPX921 has the most complex face geometry to date for additional energy from the clubface. Choose the more Pro version for a more compact profile with reduced offset.
"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."
Extreme perimeter weighting with toe bias for stability from off centre strikes.
A re-engineered COR-TECH face is now 0.2mm thinner across the center point.
A new variable thickness sole design. Resulting in greater face flex and ball speeds
