Output in context · Kagoshima United finished 5th of 20 · an upper-table side
3.32 tackles, blocks & interceptions per 90 — moderate defensive volume, with 6 clean sheets across 22 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 3 goals and 3 assists — a useful bonus from the back.
Strengths
- Attacking threat. Chips in from deep: 0.28 goal involvements per 90, useful for a central midfielder.
Watch points
- Game time. Only 54.8% of available minutes — needs a settled run to prove the level.
- Level. Rates below a nailed-on top-tier starter on our model.

Defensively he reads as moderate defensive volume (3.32 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.
