Mitsubishi Rayon’s new Fubuki J was introduced to PGA Tour players this week at the FedEx St. Jude Classic, where three players including T3 finisher Matt Every put the new shaft in play in their drivers.

The Fubuki line of shafts is best known for its use by Phil Mickelson, who played the company’s Fubuki K shaft in his Callaway X Hot 3Deep fairway wood that he used as a driver for his back-to-back wins at last year’s Scottish and British opens.

The Fubuki J shares a similar construction to the Fubuki K, using the company’s Ninja Core — a metal mesh construction that’s located in the butt section of the shaft — to prevent ovaling and improve energy transfer. It also has the company’s Modulus Differential Technology (MDT) in its tip section, a combination of different types of graphite materials that add stability and work like a hinge at impact to accelerate clubhead speed and improve launch and spin conditions.

What’s new about the Fubuki J is that it is a counterbalanced shaft, which means that its balance point has been moved farther toward the shaft’s butt section. Counterbalanced shafts are nothing new in the industry, but the way in which Mitsubishi Rayon designed the Fubuki J is. Instead of adding more graphite material to the butt section of the shaft, which can alter a shaft’s feel, the company mixes about 5 grams of tungsten powder into the materials that make up the Fubuki J’s butt section. That makes it a good fit for many of today’s heavier adjustable metal wood heads, which tend to have heavier-than-normal swing weights.

According to Mitsubishi Rayon shaft representatives on site at the FedEx St. Jude Classic, the Fubuki J was launching as much as 2 degrees higher than the Fubuki K for some players while maintaining roughly the same amount of spin.

The Fubuki J is available in four different weights: 50 grams (R, S and X flexes), 60 grams (S and X flexes), 70 grams (S and X flexes) and 80 grams (X flex). It’s currently available through authorized Mitsubishi Rayon dealers and sells for about $400. Check out the gallery below for more technical information about the shaft.
