Scout report
H. Onaga is a 31-year-old central midfielder at V-varen Nagasaki, rated 22.4 overall by Field Insider's model, ranking 171st of 193 on scout potential in the J1 League. A seasoned veteran, he has been a rotation option this season (41.2% of available minutes). His defensive output reads 3.45 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Onaga.
Judged on this season alone, Onaga graded 18 — a workmanlike campaign that ranks 19th of 41 of the 41 central midfielders in the J1 League, on 0 goals, 1 assist and 3.447 defensive actions per 90.
Year-on-year, that's broadly in line with last season (Season 16 → 18). Over the 3 seasons on record his form has drifted down, peaking in 2024/25.
On long-term talent our Rating reads 22, 39th of 41 of the 41 central midfielders in the J1 League. At 31 Onaga is into the veteran stage, where the age curve weighs on the projection, and a market index of 3.6 reflects that trajectory.
Past his 2024/25 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
Output in context · V-varen Nagasaki finished 15th of 20 · a lower-table side
3.45 tackles, blocks & interceptions per 90 — moderate defensive volume, with 1 clean sheet across 9 appearances. Doing that for a lower-table side (15th of 20) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 0 goals and 1 assist — a useful bonus from the back.
Watch points
- Game time. Only 41.2% of available minutes — needs a settled run to prove the level.
- Age curve. At 31, both level and resale value are on the downslope.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 22.4, Onaga carries the 39th-highest potential of the central midfielders in the J1 League of 41 — though on just 9 appearances this season, so the standing rests on a small sample. Defensively he reads as moderate defensive volume (3.45 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).
