Rinky Hijikata has found hard courts difficult, recording 37–48 across 85 matches (43.5%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

At Grand Slam level (Australian Open & US Open): Rinky Hijikata is 6–9 (40.0%) across 15 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

ATP Masters 1000 on hard (Indian Wells, Miami, Canada, Cincinnati, Shanghai, Paris): a positive 12–12 (50.0%) across 24 matches — winning above .500 at this level, week in week out, is a genuine sign of quality on hard.

5 quarterfinals on hard — regularly reaching that stage is a solid baseline, with the next step being to break through to the final rounds more often.

vs. Top 10 on hard: 1–11 (8.3%, 12 matches). Top 10 opponents have represented a clear ceiling on hard; addressing that deficit is the single biggest lever for improving the overall record here.

By format on hard — best-of-five: 6–9 (40.0%); best-of-three: 31–39 (44.3%). Slightly stronger in three-set contests on hard, though the five-set record is still respectable.

Best season: 2024 — 11–12 (47.8%) from 23 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.

Recent Form 2026: 11–13 (45.8%) on hard. Last 10: W W L W W L L W L L — mixed results, some inconsistency in the current period.
