Scout report

Experienced headCentral midfielder

Y. Komai is a 34-year-old central midfielder at Yokohama FC, enjoying a standout season — 0 goals and 1 assists in 21 appearances, a Season grade of 15, top 71% of J1 League central midfielders. On long-term scout potential he's rated 12.5, ranking 346th of 377 in the J1 League. A seasoned veteran, he has been a rotation option (42.9% of available minutes). His defensive output reads 3.19 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Komai.

Judged on this season alone, Komai graded 15 — a workmanlike campaign that ranks 46th of 65 of the 65 central midfielders in the J1 League, on 0 goals, 1 assist and 3.192 defensive actions per 90.

Year-on-year, that's a drop on last season (Season 42 → 15). Over the 6 seasons on record his form has drifted down, peaking in 2024/25.

On long-term talent our Rating reads 13, 63rd of 65 of the 65 central midfielders in the J1 League. At 34 Komai is into the veteran stage, where the age curve weighs on the projection, and a market index of 1.7 reflects that trajectory.

Clean sheets

3.19 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 21 appearances. Doing that for a relegation-threatened side (18th 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 42.9% of available minutes — needs a settled run to prove the level.
  • Age curve. At 34, both level and resale value are on the downslope.
  • Level. Rates below a nailed-on top-tier starter on our model.

Outlook

With a Rating of 12.5, Komai carries the 63rd-highest potential of the central midfielders in the J1 League of 65, and he is posting that for a relegation-threatened side (Yokohama FC finished 18th 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 (3.19 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.6× and falling).
