Year-on-year, that's a clear step up on last season (Season 1 → 6). Across the 3 seasons we hold, it's his best return yet.

Output in context · Roasso Kumamoto finished 18th of 20 · a relegation-threatened side
0 tackles, blocks & interceptions per 90 — light defensive volume, with 3 clean sheets across 14 appearances. Doing that for a relegation-threatened side (18th of 20) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 1 goal and 0 assists — a useful bonus from the back.
Watch points
- Game time. Only 36.8% of available minutes — needs a settled run to prove the level.
- Defensive numbers. Modest 0 defensive actions per 90 for the position.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 28.7, Iwashita carries the 30th-highest potential of the centre-backs in the J2 League of 73 — though on just 14 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.
