Clean sheets

2.97 tackles, blocks & interceptions per 90 — moderate defensive volume, with 14 clean sheets across 31 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 7 goals and 4 assists — a useful bonus from the back.

Strengths

Availability. On the pitch for 74.3% of available minutes — a dependable presence in the XI.
Attacking threat. Chips in from deep: 0.39 goal involvements per 90, useful for a defensive midfielder.

Watch points

Few red flags. No obvious weaknesses in the current-season profile — consistency is the next test.

Outlook

With a Rating of 49.4, Kubo carries the 8th-highest potential of the defensive midfielders in the J1 League (top 17%). Defensively he reads as moderate defensive volume (2.97 tackles, blocks & interceptions per 90). 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 (~22), then tapers with age. At 27, Kubo sits on 22.3, at or near its peak. The blue line is Kubo's projected Rating — 49.4 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.
