Clean sheets

3.76 tackles, blocks & interceptions per 90 — solid defensive volume, with 19 clean sheets across 38 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.

Strengths

  • Availability. On the pitch for 100% of available minutes — a dependable presence in the XI.
  • Defensive volume. 3.76 tackles, blocks & interceptions per 90 — does the unseen work.

Watch points

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

Outlook

With a Rating of 49.8, Koga carries the 6th-highest potential of the centre-backs in the J1 League (top 10%). Defensively he reads as solid defensive volume (3.76 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.
