Output in context · Osaka finished 3rd of 20 · an upper-table side
1.51 tackles, blocks & interceptions per 90 — light defensive volume, with 3 clean sheets across 15 appearances. Behind an upper-table side (3rd of 20) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 0 goals and 1 assist — a useful bonus from the back.
Watch points
- Game time. Only 19.9% of available minutes — needs a settled run to prove the level.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 16.2, Kubo carries the 67th-highest potential of the central midfielders in the J3 League of 96 — though on just 15 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (1.51 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.1× now → 0.8× projected in three years).
