Below: strengths, watch-points, market-value outlook and the latest transfer news on Sumiyoshi.
Judged on this season alone, Sumiyoshi graded 38 — a strong campaign that ranks top 18% of the 63 centre-backs in the J1 League, on 10 clean sheets and 3.126 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 9 → 38). Across the 4 seasons we hold, it's his best return yet.
On long-term talent our Rating reads 39, top 32% of the 63 centre-backs in the J1 League. At 28 Sumiyoshi is in his prime years, and a market index of 17.9 reflects that trajectory.
A career still climbing — Sumiyoshi is at his peak right now, and the curve hasn't flattened.
3.13 tackles, blocks & interceptions per 90 — moderate defensive volume, with 10 clean sheets across 33 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 0 assists — a useful bonus from the back.
With a Rating of 39.2, Sumiyoshi carries the 20th-highest potential of the centre-backs in the J1 League (top 32%), 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 moderate defensive volume (3.13 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.2× now → 0.9× 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 (~30), then tapers with age. At 28, Sumiyoshi sits on 17.9, past its peak and easing. The blue line is Sumiyoshi's projected Rating — 39.2 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.
