On long-term talent our Rating reads 20, 36th of 62 of the 62 central midfielders in the J2 League. At 30 Kojima is into the veteran stage, where the age curve weighs on the projection, and a market index of 1.8 reflects that trajectory.
Output in context · Omiya Ardija finished 6th of 20 · an upper-table side
0 tackles, blocks & interceptions per 90 — light defensive volume, with 5 clean sheets across 13 appearances. Behind an upper-table side (6th 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 1 goal and 0 assists — a useful bonus from the back.
Watch points
- Game time. Only 33.1% 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 20.3, Kojima carries the 36th-highest potential of the central midfielders in the J2 League of 62 — though on just 13 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (0 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1× now → 0.7× projected in three years).
