I. Sekigawa is a 25-year-old central defender at Kashima, rated 48.1 overall by Field Insider's model, ranking 57th of 377 in the J1 League.

Below: strengths, watch-points, market-value outlook and the latest transfer news on Sekigawa.
Judged on this season alone, Sekigawa graded 25 — a workmanlike campaign that ranks 30th of 64 of the 64 centre-backs in the J1 League, on 6 clean sheets and 2.95 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 46 → 25). Over the 6 seasons on record his form has trended upward, peaking in 2023/24.
On long-term talent our Rating reads 48, top 13% of the 64 centre-backs in the J1 League. At 25 Sekigawa is in his prime years, and a market index of 13.2 reflects that trajectory.
Read the appearance count in context: Sekigawa missed 4 games through injury (torn knee ligament) out of roughly 38 this season. The 14 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.
2.95 tackles, blocks & interceptions per 90 — moderate defensive volume, with 6 clean sheets across 14 appearances. Behind a title-challenging side (1st of 20) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume.
With a Rating of 48.1, Sekigawa carries the 8th-highest potential of the centre-backs in the J1 League of 64 — though on just 14 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (2.95 tackles, blocks & interceptions per 90). Approaching peak years; value is still building (price multiplier 2×) with the best seasons likely ahead.

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 (~13), then tapers with age. At 25, Sekigawa sits on 13.2, at or near its peak. The blue line is Sekigawa's projected Rating — 48.1 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.
