ATP Masters 1000 on hard (Indian Wells, Miami, Canada, Cincinnati, Shanghai, Paris): Yuichi Sugita has struggled at Masters level on hard: 5–10 (33.3%) in 15 matches. Improving at this level is the clearest path to a stronger overall record on this surface.

2 semifinals on hard without yet reaching a final — consistent deep runs that show the ability to string together wins across a full draw, with the step to the final still to come. 8 quarterfinals adds further depth to that picture.

By format on hard — best-of-five: 8–9 (47.1%); best-of-three: 28–51 (35.4%). Significantly better in five-set matches — a strong physical profile on hard that tends to tell as matches and tournaments progress.

Best season: 2017 — 13–10 (56.5%) from 23 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
