Below: strengths, watch-points, market-value outlook and the latest transfer news on Yamahara.
Judged on this season alone, Yamahara graded 22 — a solid campaign that ranks top 38% of the 79 full-backs in the J1 League, on 8 clean sheets and 1.233 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 19 → 22). Across the 3 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 43, top 40% of the 79 full-backs in the J1 League. At 27 Yamahara is in his prime years, and a market index of 32.5 reflects that trajectory.
Yamahara is operating at his career peak — the 2025/26 level is the level.
1.23 tackles, blocks & interceptions per 90 — light defensive volume, with 8 clean sheets across 30 appearances. Doing that for a lower-table side (14th of 20) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 1 goal and 4 assists — a useful bonus from the back.
With a Rating of 42.8, Yamahara carries the 31st-highest potential of the full-backs in the J1 League (top 40%), and he is posting that for a lower-table side (Shimizu S-pulse finished 14th of 20) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as light defensive volume (1.23 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. 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 (~33), then tapers with age. At 27, Yamahara sits on 32.5, at or near its peak. The blue line is Yamahara's projected Rating — 42.8 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.
