DriversMizuno JPX ONE DriverHow to choose between the JPX ONE and JPX ONE SELECT, and how they differ from the previous ST-MAX 230
Updated: Sep 13, 2026Contains affiliate links
Mizuno's drivers are two models released Mar 6, 2026: the JPX ONE and JPX ONE SELECT. Price, volume and length are the same. The differences are the loft options and how the head looks. I lined them up with Mizuno's official numbers.

Bottom line: how I'd choose
For forgiveness, the JPX ONE (9° and 10.5°). For a smaller-looking head you can work, the SELECT (9° only).
The price is the same ¥92,400.
That's ¥11,000 more than the previous ST-MAX 230 (¥81,400), and the face is about 11% thinner.
Drivers: JPX ONE and JPX ONE SELECT
| Model | Release date | Price (incl. tax) | Loft | Volume | Standard length | Who it suits (from the official description) |
|---|---|---|---|---|---|---|
| Rakuten Ichiba / AdJPX ONE | Mar 6, 2026 | ¥92,400 | 9 / 10.5° (±2° each) | 460cc | 45.5 in | Golfers who want both forgiveness and ball speed |
| Rakuten Ichiba / AdJPX ONE SELECT | Mar 6, 2026 | ¥92,400 | 9° only | 460cc | 45.5 in | Golfers who want a smaller-looking head and workability too |
Both use Toray's new material "NANOALLOY" in the face. Mizuno describes it as a world first.
The SELECT has a face 3mm shorter and 5mm narrower than the JPX ONE (reported by Minna no Golf Digest). Volume is the same 460cc, but it looks different at address.
There is also the "D-132" (440cc, from ¥220,000), which you order after a fitting at a direct store, but it isn't a model you buy off the shelf, so I left it out of the comparison.
Model differences and how to choose
The two models share the same 460cm³ volume, but the SELECT is shaped to look smaller at address. The face technology, 45.5-inch length and ¥92,400 price are also shared, so the difference comes down to how big the head looks and the forgiveness that follows from it. The ONE prioritizes ease, with a choice of lofts and shafts. The SELECT prioritizes workability and comes only in 9.0°, so I think it's a hard choice for anyone unsure about launching the ball high enough.
JPX ONE
Suits
- Players who want high ball speed plus forgiveness (MOI = resistance to twisting on off-center hits, and a wide high-COR area) (official description)
- Players who need 10.5° or an R shaft
- Players who naturally spin it low, around 2,000 rpm (the view of Yoshikazu Matsuo, Minna no Golf Digest)
JPX ONE SELECT
Suits
- Players who want a head that looks smaller at the same volume, plus workability (official description)
- Players with fast head speed who can launch the ball on their own (Yoshikazu Matsuo suggests about 48 m/s)
What's new in the design, and what the maker says it does
NANOALLOY face
Construction: A special resin, based on Toray's patented technology, that softens on impact. Mizuno is the first in the world to use it on a driver face, layering it 0.4mm thick over the forged titanium face (patent pending).
What Mizuno says: a titanium-only face deforms only at the center, but with NANOALLOY the whole face flexes, so the ball deforms less and less energy is lost. Mizuno says the result is “the highest ball speed in Mizuno history” (no ball-speed figure has been published).
New CORTECH face
Construction: The forged titanium base face, redesigned specifically to work with NANOALLOY.
What Mizuno says: up to about 11% thinner than the previous ST-MAX, raising ball speed and enlarging the high-ball-speed area.
Quick Switch
Construction: An adjustable sleeve that changes loft and lie (loft within ±2°).
What Mizuno says: you can set loft and lie to suit your swing and preferred ball flight. The weight is fixed and can't be swapped.
