6 clean sheets in 22 appearances (27% of games). Keeping that many behind a lower-table side (15th of 20) — a side that concedes more — points to a busy, productive season between the posts.

Outlook

With a Rating of 24.5, Ouchi carries the 6th-highest potential of the goalkeepers in the J3 League (top 34%), and he is posting that for a lower-table side (Matsumoto Yamaga finished 15th of 20) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. A rotation minutes keeper carrying the gloves this season. In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.

Market valueRating

Solid = now · dashed = projected

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 (~2), then tapers with age. At 26, Ouchi sits on 2.1, at or near its peak. The blue line is Ouchi's projected Rating — 24.5 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.
