We hold a single season for Yamamoto, 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 23, 14th of 21 of the 21 full-backs in the J3 League. At 26 Yamamoto is in his prime years, and a market index of 1.9 reflects that trajectory.
Output in context · Matsumoto Yamaga finished 15th of 20 · a lower-table side
1.17 tackles, blocks & interceptions per 90 — light defensive volume, with 4 clean sheets across 17 appearances. Doing that for a lower-table side (15th 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 0 goals and 1 assist — a useful bonus from the back.
Watch points
- Game time. Only 33.7% of available minutes — needs a settled run to prove the level.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 22.5, Yamamoto carries the 14th-highest potential of the full-backs in the J3 League of 21, and he is posting that for a lower-table side (Matsumoto Yamaga finished 15th 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 (1.17 tackles, blocks & interceptions 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.
