On long-term talent our Rating reads 52, top 3% of the 73 centre-backs in the J2 League. At 25 Nishio is in his prime years, and a market index of 9.3 reflects that trajectory.
Below his 2021/22 peak but holding a solid level — the platform for a return is there.
Output in context · Omiya Ardija finished 2nd of 20 · a title-challenging side
2.41 tackles, blocks & interceptions per 90 — moderate defensive volume, with 3 clean sheets across 25 appearances. Behind a title-challenging side (2nd 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.
Strengths
- Availability. On the pitch for 81.2% of available minutes — a dependable presence in the XI.
Watch points
- Few red flags. No obvious weaknesses in the current-season profile — consistency is the next test.
Outlook
With a Rating of 51.5, Nishio carries the 2nd-highest potential of the centre-backs in the J2 League (top 3%). Defensively he reads as moderate defensive volume (2.41 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.
