Mitsubishi, broadly, is one of the most recognizable brands in the world, owing largely to the visibility Mitsubishi Motors. Golf gearheads, however, are just as familiar with Mitsubishi Chemical, makers of some of the most popular golf shafts at both amateur and professional levels.

With respect to the latter, Mitsubishi’s history is impressive: More winning driver shafts than any other brand for 16 of the past 17 years on the PGA Tour—and the past seven years straight on the European Tour. Indeed, Mitsubishi Diamana models also have more than 270 wins and Tensei has 80. Kuro Kage and Fubuki, names well known to GolfWRXers and often seen in tour WITBs over the years, have more than 80 wins combined.

With win totals this high across multiple shaft families, it shouldn’t be surprising to hear a Mitsubishi driver shaft was played for the 500th time in a win on a major professional tour.

A little more about the makers of the Diamana DF gamed in victory number 500. In the golf equipment world, you’ll often see Mitsubishi designated “MCA.” Perhaps puzzling to the carbon fiber and kick point neophyte, “MCA” merely stands for Mitsubishi Chemical America. As a sidebar, many GolfWRXers familiar with “MCA” think it denotes the combined companies of Mitsubishi Chemical and Aldila — both venerable shaft houses in their own right — as Mitsubishi acquired Aldila in 2013, but isn’t the case.

With respect to Mitsubishi proper, the Japanese company established a carbon fiber division way back in 1974. In other words, the company, broadly, has been active in the space since, well, it was a space to be active in. Mitsubishi began making carbon shafts in 1979, doing so for decades for its domestic OEM partners in Japan.

It wasn’t until 2004, however, that Mitsubishi Rayon Composites, Inc. proper hung a shingle in Carlsbad, California, to begin developing its own branded products for sale to the aftermarket to satisfy the graphite boom.

The first solo Mitsubishi win (non co-branded shaft) came in July of 2004 at the European Open, and it was also the first victory for the Diamana.

In any industry where innovation and improvement are expected with each product iteration and where new materials are being developed all the time, it’s difficult to pinpoint inflection points and key technologies.

Nevertheless, we asked Mark Gunther, MCA’s Vice President of Sales & Marketing, to highlight a few touchstone innovations and how they informed future shaft developments.

Gunther told us the decision to use metal wire in the butt section of the Diamana Ali’Islei shaft in 2008 led to the development of the TiNi Wire prepreg (the sheets of carbon fiber and resin that are rolled together into golf shafts), which featured in the Kuro Kage line. That technology eventually begat the 304 Stainless Steel Metal Mesh, which is the centerpiece of the popular MMT (Metal Mesh Technology) iron shafts, which debuted in 2019.

Additionally, Gunther highlighted the use of pitch fiber in Diamana X shafts in 2012. Shortly after Mitsubishi merged its pitch fiber production with, at the time, Mitsubishi Rayon’s carbon fiber division to form one business unit, pitch fiber was used for the first time in an $800 Mitsubishi shaft. This led to the use of pitch fiber in the third generation of the Diamana series, and later, the popular Aldila Rogue series. It continues to be the platform for innovation in MCA pitch fiber today.

Mitsubishi has leveraged the GEARS full swing and body tracking system as a secondary testing process after running products through internal testing protocols. MMT (Metal Mesh Technology) shafts were validated via GEARS prior to PGA Tour seeding and rapid adoption by many of the game’s best.

With these innovations as a bedrock — and 500 professional wins under their belts — looking to the future, Gunther says

“There’s every reason to be excited about the future. We’ve built a very talented team that covers tours and golfers globally, we continue to create breakthrough technologies and materials that you’ve seen in Tensei Pro White 1K and in things you’ll see soon like Kai’li and Ascent, and we’re more committed than ever to validating the performance of our products through testing systems like GEARS. Whenever it’s possible to turn over a stone to help golfers shoot lower scores, we’re going to explore it.”

No doubt those explorations — and foundational shaft families like Diamana and Tensei — will have Mitsubishi’s win tally ticking toward 600 faster than, say, a Mitsubishi Lancer EVO GSR.
