Mizuno JPX is targeted at a wide cross-section of players, from the pros through to the high handicap golfers, and senior players. It is a game improvement range and designed to enhance ball speed, forgiveness and loft, through the use of a wider head and technologies like perimeter weighting and deep cavity backs.

The Mizuno MP line is meant for the pros and low handicappers, with a focus on workability, feel, feedback and the ability to shape and manipulate shots.
