Mizuno JPX ONE Driver Review – Is This The Big Shift For A Forged Iron Brand?

Mizuno have gone and done it. Best known for their buttery soft forged irons, they’ve now turned their attention to the driver head with something genuinely different.

The JPX ONE range, due January 2026, centres on what they’re calling the world’s first NANOALLOY™ driver face, developed with Toray, and it could be one of those tech leaps that actually matters on the tee.

What’s New?

The headline is the NANOALLOY™ face tech thats fresh off the press.

It’s not just marketing fluff: this is a microscopic polymer dispersion that behaves oddly clever. At rest it’s stiff, but on impact it softens slightly so it can store and return more energy than a standard titanium face.

In plain English, the face takes some of the ball’s deformation, cuts down on energy loss during compression, and keeps ball speed higher across more of the face.

CorTech Face & Thinner Sections

Mizuno pair the NANOALLOY™ with a CORTECH face that’s up to 0.35mm thinner than before, down to about 1.8mm in places.

Mizuno say that this causes the high speed rebound zone is expanded by over 15%. Translation, better forgiveness and improved distance on those off-centre smacks we all hit from time to time.

Two Flavours & Who They’re For

JPX ONE (Standard) – Bigger footprint, built-in draw bias. Think stability, high launch and an easier, straighter ball flight.

This is the point-and-shoot model for those who want confidence off the tee without faffing with a million settings.

JPX ONE Select – Smaller, tour-shaped head with neutral-to-fade bias.

Lower spin, more control and better for faster swingers who like to shape the ball. The SLR of the two, more work, more reward.

Looks, Adjustability & Length

They look sharp, deep blue gloss crown with a subtle carbon weave and a blue-tinted face that stands out without screaming for attention.

Both heads get a Quick Switch hosel with 4 degrees of loft adjustability and an adjustable rear weight to tweak swing weight and stability. Mizuno have also nudged the shaft length to 45.75 inches across the board to squeeze out a little extra yardage.

What To Expect

This isn’t just a prettier head, the tech suggests genuine gains in forgiveness and off-centre ball speed.

The standard JPX ONE should suit mid to high handicappers after straighter, higher-launching drives, while the Select will appeal to better players chasing lower spin and shot control.

As always, a fitting will sort which one matches your swing.

Final Thoughts

Mizuno stepping into bold driver tech is exciting. The NANOALLOY™ face could be a real step forward for distance and forgiveness.

If you like Mizuno’s feel and want something that helps on those imperfect strikes, the JPX ONE range is worth a look when it lands in January.

Mizuno JPX One Driver – First Impressions

Mizuno have gone for looks with the JPX ONE,it’s genuinely stunning.

Deep blue gloss crown with a subtle carbon weave and that blue-tinted NANOALLOY face gives it shelf appeal that actually translates to confidence at address.

The standard JPX ONE has a big footprint that sits very calm behind the ball, easy to like.

The Select is the compact, tour-preferred shape for better ball strikers who want less bulk.

On contact it’s generally solid and firm. The acoustics are all over the place though – some shots give a muted “carbon” thud, others a more pingy/harsh note.

The standard head carries a clear draw bias which helps square the face. Early testing doesn’t show it beating the longest drivers yet, but it’s excellent for stability and holding speed on off-centre strikes.

Its expanded high-rebound zone keeps spin and ball speed consistent, so if forgiveness matters, this one’s a legitimate contender.

Who is the Mizuno JPX One Driver for?

Mizuno’s JPX ONE range is aimed at two very different kinds of golfers.

The standard JPX ONE is the obvious game-improvement iron for average players who want maximum forgiveness and a stable platform.

Its bigger footprint and built-in draw bias help square the face at impact, so you get straighter, higher-launching shots with less fuss.

On the other hand the JPX ONE Select is for the quicker swingers and low-to-mid handicappers who want control first.

It’s a compact, tour-preferred shape with a neutral-to-fade bias, lower spin and easier shot-shaping for the player who wants to work the ball.

Both models clean up nicely in the looks department and carry Mizuno’s ball-speed tech. To sum it up like the sources did, the standard JPX ONE is a point and shoot that makes golf easier, while the JPX ONE Select is an SLR that hands the skilled player full control over the shot.
