Scout report
Y. Koizumi is a 30-year-old centre-forward at Kashiwa Reysol, enjoying a standout season — 3 goals and 3 assists in 10 appearances, a Season grade of 31, top 21% of J1 League centre-forwards. On long-term scout potential he's rated 29.5, ranking 64th of 193 in the J1 League. An experienced operator, he has been a rotation option (48.9% of available minutes). He brings 0.65 goal contributions per 90 (0.32 goals, 0.32 assists). Below: strengths, watch-points, market-value outlook and the latest transfer news on Koizumi.
Judged on this season alone, Koizumi graded 31 — a strong campaign that ranks top 22% of the 28 centre-forwards in the J1 League, on 3 goals and 3 assists in 10 appearances (0.645 involvements per 90).
Year-on-year, that's a drop on last season (Season 35 → 31). Over the 6 seasons on record his form has drifted down, peaking in 2021/22.
On long-term talent our Rating reads 30, top 40% of the 28 centre-forwards in the J1 League. At 30 Koizumi is into the veteran stage, where the age curve weighs on the projection, and a market index of 6.7 reflects that trajectory.
Below his 2021/22 peak but holding a solid level — the platform for a return is there.
Output in context · Kashiwa Reysol finished 5th of 20 · an upper-table side
3 goals in 10 appearances (0.3 per game) — light end product the role wants to see climb. He also laid on 3 assists, so the all-round involvement reads 6 goal contributions (0.6 per appearance).
Strengths
- Final-third output. 0.65 goal contributions per 90 (0.32 goals, 0.32 assists) — productive for the role.
Watch points
- Game time. Only 48.9% 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 29.5, Koizumi carries the 11th-highest potential of the centre-forwards in the J1 League of 28 — though on just 10 appearances this season, so the standing rests on a small sample. In the final third he profiles as a genuine goal threat (0.65 goal contributions per 90). Experienced and reliable, but the value curve is easing (1× now → 0.7× projected in three years).
