D. Sugioka is a 27-year-old full-back at Kashiwa Reysol, rated 40.3 overall by Field Insider's model, ranking 335th of 874 in the J3 League. In his prime years, he has been a fringe squad member this season (30.1% of available minutes). His defensive output reads 2.85 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Sugioka.
Judged on this season alone, Sugioka graded 20 — a workmanlike campaign that ranks 37th of 79 of the 79 full-backs in the J3 League, on 5 clean sheets and 2.845 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 20 → 20). Over the 6 seasons on record his form has trended upward, peaking in 2022/23.
On long-term talent our Rating reads 40, 40th of 79 of the 79 full-backs in the J3 League. At 27 Sugioka is in his prime years, and a market index of 30.6 reflects that trajectory.
Read the appearance count in context: Sugioka missed 3 games through injury (injury) 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 2022/23 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
2.85 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 14 appearances. Behind a title-challenging side (2nd 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. Going forward he chipped in 0 goals and 2 assists — a useful bonus from the back.
With a Rating of 40.3, Sugioka carries the 40th-highest potential of the full-backs in the J3 League of 79 — though on just 14 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (2.85 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.

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 (~31), then tapers with age. At 27, Sugioka sits on 30.6, at or near its peak. The blue line is Sugioka's projected Rating — 40.3 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.
