Mitsubishi Rayon's Gunther, Ibuki team up

Mitsubishi Rayon president Tsutomi Ibuki (left) moved to California in 2013 to work closely alongside Mark Gunther, a testament to the importance of the U.S. market and the PGA Tour.

Mitsubishi Rayon, headquartered in Japan, is well-known for Diamana, Fubuki and other shafts frequently seen on the PGA Tour. On the retail side, Mitsubishi Rayon sales in the U.S. have grown steadily, and Mitsubishi Rayon shaft designers here often work directly with their Japanese counterparts in product creation. Ibuki, the company’s new president, moved to Carlsbad, Calif., in 2013, a testament to the importance of the U.S. market and the PGA Tour.

In golf circles, Ibuki is known as one of the original team members behind the design and global launch of the successful Diamana shaft. The company is commemorating Diamana’s 10th anniversary with new W-Series and B-Series Diamana shafts. The W-Series and B-Series shafts are made with strong and costly pitch fiber, a form of carbon fiber that provided engineers control and stability.

Ibuki works closely with Mark Gunther, 45, recently promoted to vice president. Gunther, with an undergraduate degree in business administration and a masters degree in marketing, both from Loyola Marymount, got his start in the golf industry with Lynx Golf. He has been with Mitsubishi Rayon for 10 years.
