WRX Insider: An exclusive and very rare look inside the bag of Hideki Matsuyama



Not many bags on tour carry the mystique and secrecy that Hideki Matsuyama’s does. Yes, we have seen pictures and general WITB info, but the why and the how have been under lock and key. The only other player I can think of that shuns information snoopers as much as Hideki is Brooks Koepka. It’s not necessarily a negative thing, a player’s bag is his own and whether he chooses to share the exact ingredients is his decision.

However, today is a new day, and I was finally given an inside look into the why and how of Hideki’s bag. At a glance, it might look like any bag on tour, but it’s the nuance and the process that pique my interest. I’ve been inside the Cleveland/Srixon headquarters in Huntington Beach, California, and the guy has his own wall. That’s right, some players have a drawer or cupboard—this guy has a wall. It consists of old sets, prototypes, extra sets, and things that could work at some point. Besides Tiger’s cage at Artisan, it’s the most fascinating space I’ve seen dedicated to one player. Bryson’s old stock at Cobra is a close third, but I don’t understand half of the clubs that are in there—it’s golf nerd sightseeing on steroids, Jolt cola, and Pop Rocks.

For the purpose of this deep dive, I was able to ask some very targeted questions to one of the members of Hideki’s team who is tasked with keeping the bag humming at all times.

Thank you to Yoshihiro Iwamoto for the awesome photos!

JW: Historically, Hideki has preferred heavier shafts and swing weights. Is that to complement his unique tempo, or is it to satisfy launch conditions more?

Srixon: Hideki is constantly testing driver shafts, including lightweight options. He has found that heavier shafts allow him to generate more clubhead speed with his swing. Hideki also believes that heavier shafts help create and support his unique tempo.

JW: What launch data numbers are his sweet spot, what does the driver have to do numbers-wise?

Srixon: Hideki is very protective of his launch monitor numbers, and he is constantly tracking them and analyzing them. Based on PGA Tour launch monitor data, he averages mid-to-high 170s ball speed, low to mid-2,000s RPMs backspin, and 100 feet peak height.

JW: Any internal weighting to the driver head?

Srixon: Through the fitting process, we did quite a bit of testing and definitely explored different internal weighting options with hot melt. Hideki enjoys the test process and exhausting all options before making a final decision. With the ZX5 driver, we ended up finding a very unique place to put the hot melt, but that is a secret we prefer to keep.

JW: Is there a certain acoustic he prefers?

Srixon: Hideki has a very sensitive sense of hearing. This drives his extremely particular passion for finding the perfect sound and feel. For drivers, he prefers a higher pitch sound over a muted tone, which may also be a reason he prefers the larger game improvement shapes on woods. In addition, Hideki’s sense of sound even trickles down to his ball preference. It is incredible what Hideki can sense when ball testing, specifically in his short game and putting.

JW: What about the ZX5 has he responded the most to?

Srixon: The key factor for him was the ball speed. The ZX5 was a touch hotter for him compared to the ZX7 and it beat his previous gamer. In addition to the ball speed, he really likes the new shape of the ZX5 from the address view. This is a critical step in the introduction process. If Hideki has any issues with the address shape, he will not test the product. We included a lot of his feedback into the ZX driver shaping and masking. He prefers a very straight topline with a nice contrast between the crown and face.

JW: In testing, how did the 7 perform for him, and what were the deciding factors getting into the 5?

Srixon: We had success with both the ZX5 and ZX7 drivers. Hideki played both models in numerous PGA tournaments this year. The deciding factor for Hideki to choose the ZX5 over the ZX7 was distance. The ZX5 setup generated more ball speed and carry distance. The ZX7 setup allows him to maximize his control. During a tournament, Hideki played the ZX7 and hit over 80 percent of his fairways, but it was not carrying as far as the ZX5. He went back to the ZX5 mid-way through that event.

JW: In regards to the sole grinds, how has the sole been modified to give him the preferred turf interaction? In addition, Hideki is a player that prefers offset vs no offset?

Srixon: We are constantly adjusting to Hideki’s swing and changes to his thought process. Recently, we have added a small C-grind to the leading edge of his irons along with a flat “full” sole design. In addition, Hideki is one of the leaders in developing the toe and heel notches. He strongly believes the toe and heel notch creates a more consistent, smooth turf interaction. Hideki has always had these notches in his irons, and he was a huge part of bringing the notches back in the ZX line.

With regards to offset, Hideki prefers some offset over zero offset in his irons. He has the most specific eye, and he loves to tinker and test all products. The key areas for Hideki when it comes to irons are the general hosel shape and taper consistency, the blend between the face flat and hosel, and most importantly the smooth transitions from the hosel into the leading edge–there needs to be offset as he wants the transition to be smooth and almost straight.

JW: Beyond the sole grinds what other accommodations are made to get his irons dialed in?

Srixon: Hideki’s general iron shape has stayed consistent throughout the years. We have done some testing with different offsets, CG location, muscle and flange shaping, and topline thickness, but we generally come back to his baseline gamer. He enjoys the testing process and making sure he has the best product for his game in his bag at all times. Currently, we have been tinkering with his long irons, and he will change what is in the bag depending on the tournament. He has tested all of the new ZX products (ZX Utility, ZX5s, and ZX7s) long irons and has put the ZX Utility and ZX7 4-iron in his bag. The ZX5 and ZX7 irons had his sole ground to his spec.

Similar to the head design, he likes to test shafts all the time. Hideki is constantly looking for the best combination of the length, loft, and lie to hit the gaps he needs for that week. In terms of builds, Hideki has a very heightened sense of feel and one area that constantly comes up is how he can feel the weight. For his builds, we weight sort and document everything for each club build. We also travel with pre-cut lead tape in half-gram and one-gram increments, and Hideki will apply the tape to different areas of the club (muscle, flange, hosel, shaft), depending on how the club feels while testing. When iron testing, Hideki likes to have a full set built rather than just a few lofts. We do this because if he likes the iron while testing, then we have the full set ready to go for him to test right away.


JW: From 52 to 60, it appears that Hideki has multiple angles ground into his clubs. Can you explain each nuance and what purpose it serves?

Srixon: All three sole grinds have a similar characteristic. Hideki doesn’t change his 52-degree sole often, but he is constantly tinkering with his 56 and 60.  All three soles have a subtle C-grind shape. The 56 and 60-degree have an aggressive heel relief. Hideki also utilizes a similar subtle leading-edge grind that is in his irons. Hideki will vary the width and bounce angles of the three surfaces depending on the conditions and shots that he is looking to hit. These three tiers as well as the sole radius (the sole curvature from heel to toe) allow us to manipulate the sole design to achieve the turf interaction and versatility that he may be asking for without changing the address shape. In the 56 and 60, Hideki plays a very straight leading edge with little-to-no offset. He plays his 60 and 56 weaker to help remove the offset and maintain a very straight, smooth transition from the hosel to leading-edge


JW: Is there a miss you tend to build out of his clubs (left or right)?

Srixon: Hideki does not like to see the ball go right. He likes to hit it straight and see the ball fall left. If a driver has a right miss, it has no chance to make it in his bag.

JW: He prefers higher MOI heads. Why is that? And what is he trying to achieve more than anything?

Srixon: Spin, forgiveness, launch, speed, etc. This is driven by the address shapes. Hideki always gravitates toward larger heads at address because they look easier to hit. As stated with the irons, Hideki has an extremely critical eye, and if a product look does not meet his expectations, he won’t even try to hit/test it. This also means Hideki is always looking at all driver shapes and giving us feedback on his preference.

JW: Can you explain the detailed testing process Hideki goes through to put any club in his bag?

Srixon: Once he finds a shape he likes, we will start to dial in the performance of the driver. We typically need to manipulate the masking line between the crown paint and face to achieve the topline shape, face angle, and lie angle that he wants to see at address. Ball speed is always critical for him. The new ZX driver with Rebound Frame has really helped us improve our competitiveness this year and it has been unmatched for him, in particular with the ZX5 driver. When ball speed is sufficient, we work through the fitting process (adjusting loft, CG location, and shaft) to dial in the ball flight and spin numbers that he wants to see. If it feels good on the range, Hideki will take it to the course to confirm he can hit all the shots he needs.

JW: With his unique tempo, what types of shafts does he respond the best to?

Srixon: Hideki tests many different shafts, but the tendency is to fit him in higher kick point shafts.

    I’d really like to see how the 56 & 60 look at address both square and open. He’s one of the only guys who, like me plays a stiffer shaft in the wedges than the irons. I don’t know why anyone would want a loose shaft in a wedge

    Although I never owned one (don’t recall even ever seeing one in my local golf shops), I think Srixon makes some great looking drivers!

    Not sure having a wall of stuff on the guy that doesn’t really win anything matters. maybe get a better stable of players and see what happens.

      He’s won 5 times on the PGA Tour and 8 times on the Japan Golf Tour. He’s a proven winner. Do your research before spouting mindless statements.

    The buried lede is that Hideki is a nightmare to work with.

    I would have to agree that he is a horrific putter.
    When watching him on the putting green and he is using his alignment aids, he’s lights out.
    His problem is his set up. He sticks the toe of the putter up so far that he misses everything to the left of the hole. He will hit great putts from time to time, but they are generally right to left putts. Watch his putts and prove me wrong.

    Looks like he has put a black DI in his driver this week

      Its actually a new Proto Tour AD MD. A beefed up tip on an XC profile

    For a dude that is a notoriously horrific putter, I’d have assumed at least a mention of that part of his bag. If he ever learned to putt, he could win multiple times per year…

    I mean, I know that was a Srixon rep, so a discussion of his Scotty wasn’t gonna happen, but I’d have hoped for some mention of it somewhere.

      Hot damn u need to look up the word horrific! I know the guy works on it constantly…so between the ears has much to do with it. Great stuff to the author thanks!

    Wish the retail z forged had the toe and heel notches..

    Is there not going to be any discussion around the long hosel version of his ZX5 that’s different than the retail model? If we’re going to get deep, let’s get deep!

  12. Kenny

    Jan 6, 2021 at 10:05 am

    I don’t understand why they’re secretive about his specs. It’s not like others will suddenly copy his swingweight and lie angle or something

  13. Travis

    Jan 6, 2021 at 9:45 am

    Agree with an above comment, this was hardly a “deep dive”. There are still the exact same unanswered questions and mysteries around Hideki’s bag than before…

    Also, good god, check your articles for typos before you post. There’s at least two or three in the first half alone.

  14. Jdogg

    Jan 6, 2021 at 9:32 am

    Not really a deep dive. If it was, you’d get into why the iron shape, sole and muscle is completely different than retail? Why? Does he not like the v sole?

    • Benny

      Jan 7, 2021 at 7:14 pm

      Most of the Srixon Pros have grinned away the V Sole. Those soles are more for retail and to help us hit better shots.
      I remember him putting well with some flow neck Scotty’s and he bagged them a couple years ago but he continues to go back to a standard offset plumbers necks. .
      This article shows how amazing of a ball striker and player he is.
      Great article JW. I don’t see any typos. Know why? I could care less.

    What every bag needs most is nuance.

  16. Jordan

    Jan 6, 2021 at 9:13 am

    You’re going to need a whole article just to talk about this dude’s putters. He is testing new Scotty’s almost weekly.

  • JMB83: “I played the 3 wood with Ventus Blue 6s this past weekend, and it was a weapon off the tee. I really like the deep face for that purpose, and I appreciate the more neutral to open setup at 14*. The feel is unbelievable too.”
  • JDW3: “Got mine out on the course today. I hit it really well off the deck and off the tee. I really like that the lie angle is a little flatter. Looking forward to getting out this weekend to get in some more testing.”
  • Kale_m: “Ummmm, this thing is a cannon…Best looking 3w ever though. Turned it down a notch, and it sits perfect. A hook is my miss with the 3w. Not 1 with this in about 15 balls I hit.”

Srixon ZX7 vs Srixon 785 irons – GolfWRXers discuss



In our forums, our members have been pitting Srixon’s ZX7 irons against the brand’s 785 irons. WRXer ‘AbSWFPGA’ is currently playing the company’s 745 irons and reaches out to members for feedback on the ZX7’s and 785’s, and WRXers have been sharing their experiences with both in our forums.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • tssgj65: “I played the 785 last season. Went ahead and bought the ZX7 because of the hype. Same shaft in both, but for whatever reason, I am back with the 785. Probably no different than any other iron change, but as of now, I feel more confident with the 785’s.”
  • KPH808: “I’ve had both sets with the same shafts as well. I prefer the 785s, but the ZX7s look much better. I had the 785s in the bag for a while, but the ZX7s lasted only a few rounds.”
  • ace036: “I had the ZX7’s and also ended up going back to my Z785’s. I prefer the shape and longer blade length appearance of the Z785’s. The slightly wider sole works better for me as well.”
  • Haber: “I’ve had my Z785’s for almost 2 years now. Hoping I can go a couple more without switching. I recently demoed the zx7 and the apex pro for fun. Zx7 felt very similar and looked fantastic. Apex pro launched higher and carried a little further, but the sound and feel of the cup face made them an instant turn off. Couldn’t discern too much between the 2 Srixon offerings, so I will be sticking with my z785’s until the next round of temptation hits. I will say dollar for dollar Srixon irons are the best value in the golf market. Hundreds cheaper than the other guys and amazing quality.”
