K. Tachi is a 28-year-old central defender at Shonan Bellmare, rated 32.1 overall by Field Insider's model, ranking 519th of 874 in the J3 League. An experienced operator, he has been a rotation option this season (40.2% of available minutes). His defensive output reads 3.86 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Tachi.
Judged on this season alone, Tachi graded 12 — a workmanlike campaign that ranks 100th of 204 of the 204 centre-backs in the J3 League, on 2 clean sheets and 3.859 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 1 → 12). Over the 6 seasons on record his form has drifted down, peaking in 2022/23.
On long-term talent our Rating reads 32, 119th of 204 of the 204 centre-backs in the J3 League. At 28 Tachi is in his prime years, and a market index of 14.6 reflects that trajectory.
Past his 2022/23 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
3.86 tackles, blocks & interceptions per 90 — solid defensive volume, with 2 clean sheets across 17 appearances. Doing that for a relegation-threatened side (19th 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 1 goal and 0 assists — a useful bonus from the back.
With a Rating of 32.1, Tachi carries the 119th-highest potential of the centre-backs in the J3 League of 204, and he is posting that for a relegation-threatened side (Shonan Bellmare finished 19th of 20) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as solid defensive volume (3.86 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.2× now → 0.9× 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 (~24), then tapers with age. At 28, Tachi sits on 14.6, past its peak and easing. The blue line is Tachi's projected Rating — 32.1 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.
