Ishii S.
01/Record by surface
4 starts on all surfaces, 1 walkover listed and not counted. A count, not a record: the three records above are never added.
02/Round reached
| Stage | Entries ending here | Record at this round |
|---|---|---|
| Champion | 0 of 3 | |
| Quarterfinal | 1 of 3 | none played |
| 2nd Round | 0 of 3 | 1-0 in 1 |
| 1st Round | 2 of 3 | 1-2 in 3 |
An entry is one tournament in one season; its stage is the last round the draw shows her in, and a champion’s is the trophy. The record at a round counts matches started at that round, so a walkover moves her on without a line here.
03/By level
| Level | Starts | Hard | Clay | Grass | Titles |
|---|---|---|---|---|---|
| WTA500 | 2 | 2-0 | none | none | 0 |
| WTA1000 | 1 | 0-1 | none | none | 0 |

04/By season
| Season | Starts | Hard | Clay | Grass | Finals | Titles | Rank, newest row |
|---|---|---|---|---|---|---|---|
| 2025 | 1 | 0-1 | none | none | 0 | 0 | 188 |
| 2024 | 3 | 2-1 | none | none | 0 | 0 | 279 |
Each season is the same count over that season’s matches alone, each surface with its own starts. A season with a start on no grass court says none rather than 0-0. December openers file to the season they open. Finals counts the finals that crowned a champion, a walkover final among them, so Titles is a subset of it and a final lost shows in the gap; the surface columns count starts, which a walkover is not.
05/Head to head
| Opponent | Meetings | Record | Hard | Clay | Grass | Span | |
|---|---|---|---|---|---|---|---|
| Saito S. | 1 | 1-0 | 1-0 | none | none | 2024 | Every meeting |
| Sonmez Z. | 1 | 1-0 | 1-0 | none | none | 2024 | Every meeting |
| Raducanu E. | 1 | 0-1 | 0-1 | none | none | 2025 | Every meeting |
| Siniakova K. | 1 | 0-1 | 0-1 | none | none | 2024 | Every meeting |
| Shnaider D. | 01 w/o | none played | none | none | none | 2024 | Every meeting |
A record, never a share: the most-met opponent is Saito S., 1-0 in 1 meeting. A percentage of meetings is a win probability wearing a hat, and this section prints none. Meetings are matches started; a walkover between the two is noted and counted in neither column.

Main-draw singles on the tour, 2024 to 2025, counted from the match rows. A match ended by retirement keeps the sets that were completed and is marked; a walkover is listed with no score and enters no count. Ranks are the tour’s ranking on the day of the match. No serve statistic appears on this page: the one archive that carries them is licensed for non-commercial use only. The WTA record runs through Aug 30, 2026.
