We hold a single season for Shiohama, so there's no year-on-year comparison to draw yet — the read above is this campaign only.
On long-term talent our Rating reads 34, top 29% of the 32 centre-forwards in the J2 League. At 26 Shiohama is in his prime years, and a market index of 6 reflects that trajectory.
7 goals in 15 appearances (0.47 per game), a meaningful share of the load for a relegation-threatened side.
With a Rating of 33.6, Shiohama carries the 9th-highest potential of the centre-forwards in the J2 League (top 29%), and he is posting that for a relegation-threatened side (Roasso Kumamoto finished 18th of 20) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. In the final third he profiles as a genuine goal threat (0.57 goal contributions 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 (~6), then tapers with age. At 26, Shiohama sits on 6, at or near its peak. The blue line is Shiohama's projected Rating — 33.6 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.
