Outlook

With a Rating of 35.8, Yamamoto carries the 5th-highest potential of the centre-forwards in the J2 League of 32 — though on just 10 appearances this season, so the standing rests on a small sample. In the final third he profiles as a work-in-progress on end product (0.29 goal contributions per 90). Approaching peak years; value is still building (price multiplier 1.9×) with the best seasons likely ahead.

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 (~6), then tapers with age. At 22, Yamamoto sits on 6.1, still climbing toward its peak. The blue line is Yamamoto's projected Rating — 35.8 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.
