Read the appearance count in context: Kumasaka missed 4 games through injury (cruciate ligament) out of roughly 38 this season. The 18 he did play is a solid return on the time he was fit, and his ratings are weighted toward those games rather than the ones he sat out injured.
A career still climbing — Kumasaka is at his peak right now, and the curve hasn't flattened.
4.91 tackles, blocks & interceptions per 90 — solid defensive volume, with 9 clean sheets across 18 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.
With a Rating of 49.7, Kumasaka carries the 7th-highest potential of the defensive midfielders in the J3 League (top 13%). Defensively he reads as solid defensive volume (4.91 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.

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 (~38), then tapers with age. At 25, Kumasaka sits on 37.8, at or near its peak. The blue line is Kumasaka's projected Rating — 49.7 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.
