A seasoned veteran, he has been a rotation option this season (44.1% of available minutes). His defensive output reads 2.97 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Shirai.
Judged on this season alone, Shirai graded 19 — a workmanlike campaign that ranks 35th of 65 of the 65 central midfielders in the J1 League, on 1 goal, 1 assist and 2.974 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 15 → 19). Over the 5 seasons on record his form has trended upward, peaking in 2023/24.
On long-term talent our Rating reads 20, 55th of 65 of the 65 central midfielders in the J1 League. At 32 Shirai is into the veteran stage, where the age curve weighs on the projection, and a market index of 3.5 reflects that trajectory.
Read the appearance count in context: Shirai missed 6 games through injury (hamstring) out of roughly 38 this season. The 19 he did play is a solid return on the time he was fit, and his ratings are weighted toward those games rather than the ones he sat out injured.
Past his 2023/24 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
Output in context · FC Tokyo finished 11th of 20 · a mid-table side

Watch points
- Game time. Only 44.1% of available minutes — needs a settled run to prove the level.
- Age curve. At 32, 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 19.5, Shirai carries the 55th-highest potential of the central midfielders in the J1 League of 65. Defensively he reads as moderate defensive volume (2.97 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.8× and falling).
