Target Japan Kosuzu Iwao Diamond G4 90% Tungsten Swiss Point Steel Tip Darts

Developed with Kosuzu Iwao (いわお小鈴), DIAMOND G4 reworks the “Diamond” concept into a blend of beauty, precision and performance, with this fourth-generation model capturing Kosuzu's confident, radiant presence both on and off the stage.

At its core sits a signature triple diamond ring motif, taking inspiration from stacked jewellery rings. The result is a fashionable, layered look that pairs artistic styling with real functional precision.

• Each of the three diamond rings uses a different groove depth and shape, giving varied grip textures that boost control and help prevent slipping.
• The stacked-ring structure lets the fingers naturally recognise their position, supporting consistent throws and a stable release.

Like fine jewellery, the triple ring pattern carries real elegance, a fusion of strength and sophistication.

Vivid red line accents reflect Kosuzu's favourite colour, tying the barrel to the DIAMOND series' vibrant art direction. Beyond the visual impact, the red detailing is meant to evoke energy, confidence and passion, mirroring the player's own fiery determination.

The straight barrel profile is built for versatility and balance, offering smooth, adaptable handling suited to beginners and advanced players alike. Softened shark cuts on the front section give a smooth, responsive touch for a controlled release. The centre section carries the signature diamond-pattern cuts alongside ring grooves for precise feedback and visual flair, while alternating mild shark cuts at the rear provide a moderate but firm grip that's easy to find and hold.

Every part of the barrel is arranged to deliver grip stability across all hand positions, supporting a wide range of throwing styles.

DIAMOND G4 carries the series' legacy forward, combining competitive performance with fashion-led design. A sleek black body, bold red accents and geometric precision embody the brilliance of its name and reflect both strength and individuality. Stylish, versatile and powerful, DIAMOND G4 is the next evolution of the range, ready to shine in every game.
