Naoyuki Oi

Naoyuki Oi, nicknamed "Shotgun", ranks among Japan's most accomplished players, with a pair of World Nineball Tour ranking titles to his name. His first came at the 2024 Taom Maxrack Nineball Helsinki Open, and he added a second at the inaugural 2026 Carabao International Open.

Oi has also proven himself on the biggest stages, reaching the final of the 2025 European Open — one of several deep runs that have kept him among the tour's most consistent performers.
