Below his 2024/25 peak but holding a solid level — the platform for a return is there.
0 tackles, blocks & interceptions per 90 — light defensive volume, with 4 clean sheets across 13 appearances. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.
With a Rating of 41.1, Nishiya carries the 92nd-highest potential of the central midfielders in the J3 League of 241 — 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). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 23–27 (~31), then tapers with age. At 26, Nishiya sits on 31.2, at or near its peak. The blue line is Nishiya's projected Rating — 41.1 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines. Solid = up to today; dashed = projected.
