On long-term talent our Rating reads 25, 44th of 72 of the 72 goalkeepers in the J3 League. At 30 Yoshimaru is into the veteran stage, where the age curve weighs on the projection, and a market index of 9.5 reflects that trajectory.
2 clean sheets in 13 appearances (15% of games).
With a Rating of 25, Yoshimaru carries the 44th-highest potential of the goalkeepers in the J3 League of 72 — though on just 13 appearances this season, so the standing rests on a small sample. A limited game time keeper carrying the gloves this season. Experienced and reliable, but the value curve is easing (1× now → 0.7× projected in three years).

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 (~19), then tapers with age. At 30, Yoshimaru sits on 9.5, past its peak and easing. The blue line is Yoshimaru's projected Rating — 25 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.
