Target Japan - Yuta Hayashi Sirius G4 - 90% Tungsten Darts (SP)

The Tokyo qualifier winner's exact dart

The Prime Series Sirius G4 is designed in collaboration with Yuta Hayashi — and this is the exact model he used to win the 2025 Tokyo Super Darts Qualifier. A verified buyer gave the set five stars, praising the customer service and extremely quick delivery.

A step in the centre, knurl at the front

The 90% tungsten barrel runs a straight design with a tapered nose and a distinctive step machined into the centre — a positive reference that supports a smooth, controlled release. Multiple knurled radial grooved cuts provide enhanced finger grip at the front for stability through the throw, at a balanced 3/5 overall. Two weights share a 51mm length: 6.70mm at 22g and 6.90mm at 24g.

Nano Swiss front, K-Flex rear

Nano Swiss Points ride Target's patented locking system — secure through play, swapped in seconds with the included SP tool (spares here). The 26mm intermediate K-Flex integrated flight-and-shaft units hold the petals at a constant 90 degrees, with the shaft section engineered to move on impact and cut bounce-outs. For the previous chapter, the Sirius Gen 3 shows where the G4's refinements came from.
