Mitsubishi Golf is the golf-focused division of Mitsubishi Chemical America, a vertically integrated manufacturer of premium graphite golf shafts—ranging from the groundbreaking Diamana series (introduced in 2004 with its iconic White/Blue/Red board profiles) to innovative lines like Tensei, Kuro Kage, Fubuki, MMT, and Vanquish—all built using proprietary raw materials and in‑house carbon‑fiber prepreg production to ensure top-tier performance and consistency. With over 500 professional tournament wins since 2004—including on the PGA and European Tours—and widespread adoption among both tour pros and amateurs, Mitsubishi Golf shafts are praised for their feel, stability, and tailored launch/spin characteristics .
