Designed for young golfing prodigies ready to take their first steps towards greatness, the Mizuno JM01 140 is a complete 7-piece junior golf set purpose-built for players aged 10–12 years with a height of approximately 140–160 cm. Mizuno, renowned worldwide for its high-quality and high-performance golf clubs, brings this expertise to the junior market with a set that delivers the perfect balance of lightweight feel and genuine on-course performance. Every club in the JM01 140 has been scaled and engineered specifically to suit the swing speed, strength, and stature of developing junior players, giving them the confidence and equipment to grow their game season after season.
The 330cc driver head features a 16° loft angle — higher than a standard adult driver — specifically chosen to help junior golfers launch the ball on an optimal trajectory with lower swing speeds. The generous head volume (330cc) provides a larger sweet spot and forgiving face, so off-center strikes still travel a useful distance. At 40 inches in length and just 281 g total weight, the driver is easy to control and helps young players develop a repeatable swing tempo from their very first rounds.
The 130cc fairway wood (23°) and 120cc hybrid (30°) bridge the crucial distance gap between the driver and irons. Both clubs feature elevated lofts to ensure easy launch from fairway lies, semi-rough, and even light rough — situations that a developing junior will encounter constantly. The hybrid in particular is a forgiving alternative to long irons, allowing young players to confidently cover mid-range distances and learn to shape their approach play. All carry the lightweight Exsar graphite shaft for smooth, effortless acceleration.
The set includes a 7-iron (36°), 9-iron (44°), and sand wedge (54°) — a thoughtfully chosen trio that covers approach shots, pitching, and greenside play. Loft angles are optimised for junior swing speeds so the ball gets airborne quickly and lands softly on greens. Club lengths are stepped down progressively (34", 33", and 32.5") so each club feels natural in the hands of a 140–160 cm golfer. The Exsar graphite shafts keep overall weight low (336 g to 361 g), reducing fatigue during a full round.
The included putter is fitted with the JR Original shaft — a junior-specific putter shaft designed to provide the right feel and feedback for smaller hands and shorter stances. At 31 inches in length and 430 g total weight, it sits perfectly in the setup of a 10–12-year-old golfer. The 2° loft and 72° lie angle are calibrated to encourage a proper putting stroke, helping young players build the consistent roll and distance control they need on the greens from an early age.
All clubs except the putter are fitted with the Exsar graphite shaft — a lightweight, junior-optimised graphite design that reduces total club weight and lowers the effort required to generate swing speed. Graphite shafts are the preferred choice for junior golfers because they absorb vibration at impact, making off-center strikes more comfortable. The J-Flex designation indicates a soft, junior-appropriate flex profile that helps players with developing swing speeds launch the ball consistently and build good swing mechanics without fighting the shaft.
The JM01 140 set comes complete with a premium junior stand bag featuring a dual-strap carry system, making it lightweight and comfortable for young golfers to carry themselves around the course. The bag is sized appropriately for junior clubs, keeping them organized and protected. A stand mechanism allows the bag to stand upright on the fairway, making club selection quick and easy during the round. The inclusion of the bag means the set is truly complete — a young golfer can open the box and head straight to the first tee.
