K. Masui is a 25-year-old central midfielder at Jubilo Iwata, rated 46.7 overall by Field Insider's model, ranking 157th of 874 in the J3 League. In his prime years, he has been a fringe squad member this season (25.9% of available minutes). Below: strengths, watch-points, market-value outlook and the latest transfer news on Masui.
Judged on this season alone, Masui graded 6 — a workmanlike campaign that ranks 162nd of 241 of the 241 central midfielders in the J3 League, on 2 goals, 0 assists and 0 defensive actions per 90.
Year-on-year, that's a drop on last season (Season 11 → 6). Over the 3 seasons on record his form has trended upward, peaking in 2024/25.
On long-term talent our Rating reads 47, top 17% of the 241 central midfielders in the J3 League. At 25 Masui is in his prime years, and a market index of 35.5 reflects that trajectory.
Below his 2024/25 peak but holding a solid level — the platform for a return is there.
0 tackles, blocks & interceptions per 90 — light defensive volume, with 3 clean sheets across 13 appearances. Behind an upper-table side (5th 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 2 goals and 0 assists — a useful bonus from the back.
With a Rating of 46.7, Masui carries the 39th-highest potential of the central midfielders in the J3 League of 241 — though on just 13 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (0 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 (~36), then tapers with age. At 25, Masui sits on 35.5, at or near its peak. The blue line is Masui's projected Rating — 46.7 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.
