Target Japan Sirius G4 90% Tungsten SP Steel Tip Darts

The Prime Series Sirius Generation 4 was developed with Yuta Hayashi, a rising star and recent Japan Pro Tour champion. This fourth-generation barrel pairs astronomical styling with competitive precision, built as a 90% tungsten straight barrel inspired by old star charts—think grid textures, circular formations and constellation-style dot detailing.

The grip zone blends 3D grid textures with ring cuts for a secure, balanced hold, while silver micro-dots and a laser-etched star symbol add detail to the black PVD-coated barrel. Yuta's own signature purple finish represents the depth of space—a barrel built to perform and designed to shine, much like the star it's named after.

Each set comes with Target's Swiss nano points, cut with fine nano grooves for extra board grip. Thanks to Target's patented Swiss Point system, swapping points takes seconds with the included tool.

The set is finished with blue K-Flex No.6 integrated flights and shafts—a fully moulded system built for consistency and durability. Produced through advanced injection moulding, K-Flex absorbs impact, cuts deflections and prevents flight dropouts, with a fixed 90-degree flight angle and universal 2BA thread for smooth, uninterrupted play.
