Designed for young golfing prodigies ready to take their very first steps towards greatness, the Mizuno JM01 120 is a complete 5-piece junior golf set built specifically for children aged 7–9 years with a height of approximately 119–140 cm. Engineered with Mizuno's legendary commitment to quality and performance, the JM01 120 delivers the ideal balance of lightweight feel, easy playability, and course-ready performance — giving young players every reason to fall in love with the game from day one. Lightweight graphite shafts matched to junior swing speeds make the clubs easy to swing, helping beginners develop proper technique and build confidence right from the start.
The Exsar graphite shaft is the backbone of the JM01 120 set. Engineered specifically for junior swing speeds, its ultra-light construction reduces overall club weight so young players can swing freely without fatigue. The J-Flex rating matches the lower swing speeds typical of 7–9 year olds, helping them load the shaft correctly and release maximum energy through impact. Club lengths are precisely calibrated — from 36" for the driver down to 28" for the 9-iron — to match the proportions of a child in the 119–140 cm height range and encourage correct posture and ball-striking fundamentals from day one.
The 16° driver features a 330 cc head — compact enough for junior hands yet generous enough to offer a forgiving sweet spot. The high loft angle helps younger players who haven't yet developed a powerful swing to still get the ball airborne with a penetrating trajectory. The 23° fairway wood (130 cc head) complements the driver perfectly, offering an easier-to-hit alternative off the tee and from the fairway. Both woods are fitted with protective headcovers to safeguard the clubheads during transport and storage.
The JM01 120 includes two carefully chosen irons — a 7-iron (36° loft) and a 9-iron (44° loft) — that cover the full range of approach distances a junior golfer will encounter on the course. The clubhead geometry is specifically designed to be forgiving on off-centre strikes, with a weight distribution that keeps the centre of gravity low to promote easy, high-flying shots. At 29" and 28" respectively, these irons are sized to suit the arm length and stance width of children in the 119–140 cm range, helping them build consistent, repeatable ball-striking from the very beginning.
The putter is fitted with the dedicated JR Original shaft — a purpose-built junior putter shaft that delivers the right balance of stiffness and feel for small hands and shorter strokes. At 26" in length and a 2° loft, the putter is optimised to get the ball rolling smoothly on the green. The 72° lie angle positions junior players in an ergonomically correct stance, naturally encouraging the shoulder-driven, pendulum-style putting stroke that coaches recommend for beginners. A putter headcover is also included to protect the face during transport.
The included Mizuno junior stand bag is designed to be as light and easy to manage as possible, so young players can carry their own clubs around the course and develop independence and confidence. Built-in retractable support legs keep the bag upright on the fairway or green, and multiple storage compartments provide space for balls, tees, gloves, and other accessories. Mizuno's stylish aesthetic ensures young golfers look the part from their very first round.
