First impressions of the Mizuno JPX900 irons
It’s always very exciting to see some new Mizuno irons as you know they will look, feel and perform fantastically well.
They’ve sprung a few surprises this year by launching three new Mizuno JPX900 irons – each with a different look and feel, and each aimed at a different kind of player.
We’ve got JPX900 Hot Metal, JPX900 Forged and JPX900 Tour.

I’d always considered the Mizuno JPX irons to lean more towards the game-improvement market but the previous JPX850 Forged were such a big hit with players of all abilities – from high handicappers to tour players – that we’ve now seen more of a shift.
The Mizuno JPX900 Hot Metal are the largest and most confidence-inspiring of the three, the JPX900 Forged are much sleeker while the JPX900 Tour are more of a traditional blade.
For me, there’s more shelf appeal with the Mizuno JPX900 Hot Metal compared to the previous JPX850 non-forged model. So much so that I think you could blend all three of these new irons into a combo set.
There’s a satin finish on the JPX900 Tour which really make them stand out at there’s nothing like them on the market at the moment.
Technology in the JPX900 irons
We’ve got three different materials in each of the irons which is key to their performance.
Mizuno have used Chromoly in the JPX900 Hot Metal which they say has allowed them to add their thinnest-ever face which will really get the ball coming off at high ball speeds.

It is also a very versatile metal which opens up the door for more precise lie and loft adjustments for proper custom-fitting.
In the JPX900 Forged we again see Mizuno using the performance benefits of Boron. The Boron-infused steel gives a really nice soft feel but still produces high ball speeds.

Boron is a very dense material which means Mizuno can pack a load of performance benefits into the iron while still maintaining a look that elite players will enjoy.
