ReviewsMizuno JPX ONE Driver ReviewScoring the JPX ONE and JPX ONE SELECT on construction and numbers
Updated: Sep 14, 2026Contains affiliate links
I'm a golf gear nerd. I cross-check head materials, construction and weight placement against official specs and third-party measurements and test reviews, and I write the weaknesses before the strengths.
The Gear Nerd's Bottom Line Overall ★★★★★ 3.3 / 5
“A club that helps low-spin players get easy distance.” I don't recommend it for players who already spin the ball a lot, or for anyone stretching to play the SELECT.
Buy it if
- Players with low spin, around 2,000 rpm (ONE)
- Players with 43 m/s+ head speed who want a strong, low-spin ball flight (SELECT)
- Players who care about how the club looks at address (it rates highly for ease of alignment)
Pass if
- Players who spin it 3,000 rpm or more (risk of ballooning)
- Players who want a draw-biased head to fix a slice
- Players under 43 m/s head speed who are eyeing the SELECT
The JPX ONE in one minute
A face with a 0.4mm resin layer over forged titanium. Mizuno says it's a world first for a driver face. As a gear nerd, I get honestly excited by a design this bold. It isn't for everyone, though.
What I like
- A face with 0.4mm of NANOALLOY over forged titanium
- The ONE's measured MOI is 5,199 g·cm², higher than the norm
- Highly rated for how it sets up at address (4.9 in my caddie's category scores)
- The sleeve adjusts loft by ±2°
What I don't like
- Tests in Japan and abroad found a bit too much spin, which holds back distance
- Reviews of the feel split between soft and firm
ONE or SELECT?
- ONE: for lower-spin players at around 2,000 rpm. Also the one if you need 10.5° or an R shaft
- SELECT: 9° loft only. Most testers put the guide at a head speed of 43 m/s (about 96 mph) or more
- Skip both: players who spin it at 3,000 rpm or more. Shots may balloon
If you're unsure, go with the ONE. I don't recommend reaching for the SELECT. Also know up front that the weight is fixed on both models and can't be swapped.

Bottom line: how I'd choose
“A club that helps low-spin players get easy distance.” I don't recommend it for players who already spin the ball a lot, or for anyone stretching to play the SELECT.
If I had to name one weakness: “too much spin, so it doesn't reach full distance.”
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)
Better off skipping it
- Players who usually spin it 3,000 rpm or more (Yoshikazu Matsuo warns it may balloon)
- Players who want to swap weights to fine-tune ball flight (weight is fixed)
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)
Not for players who struggle to get the ball up
- Players who struggle to get the ball up (Japan-spec loft is 9.0° only)
- Players who value help on off-center hits (in media measurements its MOI is lower than the ONE's: ONE 5,199 vs. SELECT 4,664 g·cm² / Minna no Golf Digest)
- Players who need an R shaft (S and SR only)
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.
Scored in six categories
| Aspect | Score | Why (from construction and numbers) |
|---|---|---|
| Distance design | ★★★★★ 3.0 | High ball speed, but a bit too much spin to reach full distance (Sponavi's Orangeman). About 3,200 rpm in an overseas test |
| Forgiveness (straightness) | ★★★★★ 4.0 | The ONE's measured MOI of 5,199 g·cm² is above standard (4,600–4,799). The SELECT, at 4,664, is about standard |
| Feel & sound | ★★★★★ 3.0 | Opinions split: “soft, grabs the ball” (Sponavi) vs. “a little firm and dull” (Golf Monthly) |
| Workability | ★★★★★ 3.0 | The ONE favors straightness over workability. The SELECT is neutral with little curve |
| Adjustability | ★★★★★ 3.0 | Has a sleeve (Quick Switch), but weight mass and whether it can be swapped weren't confirmed on the Japanese official site |
| Value for money | ★★★★★ 3.5 | ¥92,400 (¥11,000 more than the previous ST-MAX 230). Seen online at about 20% off |
Construction through a gear nerd's eyes
The headline feature is the face. A 0.4mm layer of Toray's special resin, NANOALLOY, sits on top of the forged titanium face (Mizuno official). According to Mizuno, the material softens the instant it's struck, letting the whole face flex to reduce energy loss.
What catches the Gear Nerd's eye is that there's a separate layer of material on the surface the ball hits. That kind of construction tends to make the feel seem softer, but it also changes how the face grips the ball. Many testers write that “ball speed is high but spin runs a bit high,” and I think this layer may play a part (that's my guess, not Mizuno's explanation). Some user reviews also mention that “tee marks show up on the face,” which is worth knowing if you care about how the face looks.
The body is Ti811, and the official materials list names carbon only for the crown. The weight is SUS304 (stainless), which Minna no Golf Digest describes as “one at the rear of the sole.” The number that bothered me is the low-CG ratio. The measured 68.3% is higher than standard (62.0–63.9%), and Yoshikazu Matsuo calls it a “high-CG design.” If you're choosing it just because it looks forgiving at address, check this number first.
Cons
1. Too much spin, so it doesn't reach full distance
Sponavi's Orangeman (HS about 45 m/s) wrote that “ball speed is high but spin is a bit high,” and Golfalot overseas rated about 3,200 rpm as “too much.” Club designer Yoshikazu Matsuo also notes that players who usually spin it 3,000 rpm or more will see it balloon with little roll. A domestic test, an overseas measurement and a designer's view all point the same way from different positions, so I see this as the biggest weakness.
2. Some say the feel and sound aren't what they expected
Golf Monthly calls it “a little firm and dull”; for the SELECT, a Golf Do! user review says “it felt firmer than I expected,” and one on my caddie says “the feel is very hard.” Sponavi, on the other hand, calls it “soft, grabs the ball.” With opinions this split, if feel is your reason to buy, the only way to know is to hit it yourself.
3. The SELECT is unforgiving on mishits and comes only in 9°
The SELECT's measured MOI is 4,664 g·cm², about standard. Golf Monthly notes it's weak on heel misses, and several testers suggest a head speed of 43 m/s or more. The Japan-spec loft is 9° only. This isn't a model to stretch for.
What still earns credit
It rates highly for ease of alignment: 4.9 in my caddie's category ratings, and 4.2 in user ratings on the GDO catalog. The ONE's MOI is above standard, and one test (Sponavi) found it squares the face well too. Even the extra-spin weakness helps hold the ball up for players who naturally spin it low. For players with low spin or modest head speed who want easy distance from a good-looking head, I think it's worth the price.
Numbers vs. the previous model and rivals
| Item | Previous ST-MAX 230 | JPX ONE |
|---|---|---|
| Length | 45.75 in | 45.5 in |
| Total weight (S) | About 299g | approx. 310g |
| Carbon (official listing) | Crown, sole | Crown |
| Price (incl. tax) | ¥81,400 | ¥92,400 |
Who it suits, who it doesn't, and alternatives
Mizuno doesn't state a target head speed. The guide I'd use is Yoshikazu Matsuo's view: the ONE suits players with around 2,000 rpm spin or who lack confidence in their power, and the SELECT suits players around 48 m/s who can launch the ball on their own. Some of you may be drawn to the SELECT because it looks like the better player's club, but if you don't meet that bar, I think the ONE will give steadier results. If you want a draw-biased head to fix a slice, try draw-leaning models like the PING G440 or Callaway QUANTUM MAX D first.
FAQ
What's the difference between the JPX ONE and JPX ONE SELECT?
The ONE is a forgiving, high-MOI design; the SELECT has roughly standard MOI and leans low-spin. The Japan-spec SELECT comes only in 9° loft, and most testers suggest a head speed of 43 m/s or more.
What's different about the NANOALLOY face?
A 0.4mm layer of resin that softens the instant it's struck sits on top of the forged titanium face. Mizuno says the aim is to let the whole face flex and reduce energy loss.
