Mizuno fitting
Would you like to find out your swing personality = SWING DNA?
Mizuno fitting will "transform" your golf.
There are as many swings as there are golfers. Each person has their own values, playing style, skill level, and concerns.
We promise to deliver the best golf clubs that perfectly match your swing DNA, based on scientific evidence derived from the latest technology and the experience and know-how we have cultivated over the years.
NIKI GOLF has the largest number of manufacturer-certified fitters.
No. 1 in the industry
Since 2004, NIKI GOLF has been working to train Mizuno-certified club fitters, and in 2012, all stores except Ameyoko Flagship Store were certified as MPF stores (Mizuno Performance Fitting stores), the predecessor of GCF stores. Moving forward, based on our experience and the trust of our customers, we will continue to provide even higher-level fitting services as a member of the GCF store network.
Customer feedback after fitting
(Male, 50s) The staff were very polite and explained things clearly.
(Woman in her 30s) It was my first fitting, so I was a little intimidated, but they made me feel relaxed and at ease, so I was able to leave it to them.
(Man in his 40s) I felt that their knowledge and experience was far superior to other retailers. I would like to continue using their services in the future.
Hit three balls and your golf game will change.
Mizuno's exclusive Shaft Optimizer is a measuring device that can instantly measure your swing characteristics (SWING DNA) by simply hitting three balls.
After eight years, the Shaft Optimizer, which has accumulated data on over 600,000 people, will debut as the new SET OPTIMIZER on Tuesday, December 23, 2025.
First, discover your swing's unique "SWING DNA"
We believe that the most effective way to fit a golfer is to understand their innate "SWING DNA." The new Set Optimizer measures 10 data points in a player's swing to discover their SWING DNA. From there, a Mizuno fitter will work with you to select the clubs that will bring you closer to your ideal distance and trajectory.
Find the shaft and head that's right for you based on your SWING DNA
Using the Mizuno Performance Fitting System, we will create a list of over 50 shafts and iron heads that are best suited to you based on your swing DNA. We will then recommend the best club for you based on the measurement results and test shots.
The only device in the world that can measure drivers, irons, and wedges with one device
The Set Optimizer can measure the driver, iron, and wedge all with one device. The Set Optimizer is the only technology in the world that can measure the shaft movement and swing behavior of three types of clubs with a single device. (Mizuno patent pending)
For irons
In addition to the nine existing parameters, a new parameter, "Rotation Rate," has been added for even greater accuracy. Based on your SWING DNA, you'll find the recommended shaft, head, and lie angle that's right for you.
For wedges (Available only at participating stores)
We've developed a new measuring device specifically for wedges that measures the swing DNA of your approach shots and suggests the optimal wedge bounce and grind for you.
For drivers (scheduled to begin operation in February 2026)
We have developed a new measuring device specifically for drivers that measures the swing DNA of each driver and suggests the optimal shaft, head type, and loft specifications.
What is SWING DNA?
It is the individuality of each individual golf swing.
The habits and characteristics of a golf swing that golfers are born with are called SWING DNA.
Except for changes in muscle strength and the effects of injury or illness, there is little change as your golf level improves.
Discovering your SWING DNA and finding the club that suits you will help you improve your golf game.
Elements of SWING DNA
There are 10 key elements to SWING DNA.
These factors are used to determine the shaft, head, and lie angle that best suits the player.
Head speed
Head speed just before impact
Swing Tempo
Shaft deflection at the top
Toe Down
Amount of shaft deflection in the toe-down direction just before impact
Front camber angle
The angle at which the shaft bends forward (towards the ball flight) at impact
Flexibility coefficient
Degree of flex during swing
Impact lie angle
The angle between the shaft and the horizontal plane
Shaft lean angle
Angle between the shaft and the vertical plane in the forward and backward direction
Angle of Attack
The angle between the head's direction of travel and the horizontal plane
Face-to-path angle
The angle between the direction of the club face and the direction of the club head movement
Rotation Rate
The magnitude of face rotation just before impact
Club fitting process
When you hit three shots with a club equipped with the Set Optimizer, it instantly measures 10 aspects of your swing characteristics, or SWING DNA.
From the measurement results, the optimal shaft stiffness, weight, and kick point are identified and a list of recommended shafts is provided.
At the same time, the optimal head type and lie angle will be identified and a list of recommended models will be made available.
Based on the recommended shaft and model, the fitter will select and assemble the shaft and head, taking into consideration your golf style and preferences.
You will be asked to try out the assembled club, and the fitter will check the impact point, etc. They will then fine-tune the club to perfectly match your swing DNA.
If you can hit the shot you imagine, then you have the perfect club.
