We hold a single season for Kubo, so there's no year-on-year comparison to draw yet — the read above is this campaign only.
On long-term talent our Rating reads 29, 169th of 241 of the 241 central midfielders in the J3 League. At 29 Kubo is in his prime years, and a market index of 12.1 reflects that trajectory.
1.51 tackles, blocks & interceptions per 90 — light defensive volume, with 3 clean sheets across 15 appearances. Behind an upper-table side (3rd 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 1 assist — a useful bonus from the back.
With a Rating of 29, Kubo carries the 169th-highest potential of the central midfielders in the J3 League of 241 — though on just 15 appearances this season, so the standing rests on a small sample. Defensively he reads as light defensive volume (1.51 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.1× now → 0.8× projected in three years).

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 (~22), then tapers with age. At 29, Kubo sits on 12.1, past its peak and easing. The blue line is Kubo's projected Rating — 29 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.
