── Pre-Race Slope Work × 1-Week-Prior Work × Race-Week Work × WHGR ──
April 12, 2026 (Sun) Nakayama Race 9 | Dirt 2400m | 12 runners | Post time 14:15
Introduction
The Inzai Tokubetsu is a handicap race over 2400 meters on dirt. Long-distance dirt races produce a wide variety of runners, and the way each stable prepares its horses is highly individual. This article analyzes the field from three axes: pre-race slope work theory, one-week-prior vs. race-week readiness comparison, and WHGR.
1. Horse + Jockey Combined WHGR Ranking
| Rank | # | Horse | Jockey | Horse | Jockey | Total |
|---|---|---|---|---|---|---|
| 1st | 3 | Shigeru Kamikaze | Takuya Ono | +300 | +300 | +600 ★★ |
| 2nd | 2 | Corlin Carvela | Yutaka Yoshida | +150 | +300 | +450 ★★ |
| 3rd | 12 | Indicator | Osuke Tayama | +150 | +150 | +300 ★★ |
| 4th | 1 | Ocean Half | Kazuo Yokoyama | +80 | +190 | +270 ★★ |
| 4th | 10 | Rafale d’Or | Takuya Kobata | +190 | +80 | +270 ★★ |
| 7th | 7 | Ootachi | Dai Sasaki | +45 | +100 | +145 ◎ |
#3 Shigeru Kamikaze (Takuya Ono) tops the chart at +600, with both horse and jockey at +300 — matching the day’s highest values alongside Juryoku Pierrot in the Wasurenagusa Sho. #2 Corlin Carvela (Yutaka Yoshida) also scores a high +450.
2. Pre-Race Slope Work — Only 4 of 12 Runners
Pre-race slope ranking (Saturday, April 11)
| Rank | # | Horse | 4F | 1F | Lap | Stable |
|---|---|---|---|---|---|---|
| 1st | 11 | Casstrop | 66.0 | 15.6 | Accel | Kazuyuki Ogata |
| 2nd | 7 | Ootachi | 68.3 | 15.8 | Accel | Takashi Kubota |
| 3rd | 10 | Rafale d’Or | 69.8 | 16.8 | Decel | Toshiaki Tajima |
| 4th | 4 | Rompaire | 71.4 | 18.0 | Decel | Tomohito Ozeki |
The top two (#11 and #7) posted accelerating laps. #7 Ootachi with jockey Dai Sasaki also fits the B-1 confirmed pattern.
3. 1-Week-Prior vs. Race-Week — Readiness Comparison
Readiness Pattern Classification
| # | Horse | 1 Wk Prior | Race Wk | Change | Pattern |
|---|---|---|---|---|---|
| 8 | Mugello | Slope 54.5★ | None (Wood 66.9◎) | Switch | Peaked |
| 7 | Ootachi | Slope 54.9◎ | Slope 55.2◎ | +0.3 | Stable |
| 12 | Indicator | Slope 56.4 | Slope 56.6 | +0.2 | Stable |
| 1 | Ocean Half | Slope 65.2 | Slope 54.3★ | −10.9 | Race-Wk Spike |
| 6 | Earth Aios | Slope 69.5 | Slope 66.7 | −2.8 | Improving |
Notable Woodchip Workouts
| # | Horse | Race-Wk Wood 5F | Notes |
|---|---|---|---|
| 10 | Rafale d’Or | 66.6 (fastest) | 1 wk 68.6→race-wk 66.6 improving + pre-race slope |
| 8 | Mugello | 66.9 | Slope 54.5★ 1 wk→switch to wood. Fujiwara Hideaki stable |
| 2 | Corlin Carvela | 67.2 | WHGR +450★★. Race-wk wood only |
| 3 | Shigeru Kamikaze | 67.8 | WHGR +600★★. 1 wk 88.4→race-wk 67.8 big improvement |
4. Win-Bet Strategy Pattern Matching
◎ #7 Ootachi / Jockey Dai Sasaki — B-1 confirmed pattern (Heavenly Stem = 壬 [Mizunoe], OOS recovery rate 195.6%). Slope 54.9→55.2, stable. Pre-race slope 2nd (accelerating). Dual confirmation from training and pattern data.
Note: #8 Mugello / Jockey M. Dee — Last day of short-term license. Entered by the Fujiwara Hideaki stable with a 54.5-second slope workout (fastest in field) one week prior. Strong intent to win, but no WHGR data available (jockey birth date unknown).
5. Overall Assessment
| # | Horse | Pre-Race Slope | Readiness | WHGR | Pattern | Overall |
|---|---|---|---|---|---|---|
| 7 | Ootachi | 2nd, Accel | Stable 54.9→55.2 | +145◎ | B-1 Confirmed | A |
| 8 | Mugello | None | Peaked 54.5★→Wood 66.9 | — | Last-day ride | A |
| 3 | Shigeru Kamikaze | None | Wood 88.4→67.8 big cut | +600★★ | — | B+ |
| 10 | Rafale d’Or | 3rd | Wood 68.6→66.6 fastest | +270★★ | — | B+ |
| 2 | Corlin Carvela | None | Wood 67.2 only | +450★★ | — | B |
Conclusion
1. #7 Ootachi (Dai Sasaki) checks all three boxes: training, pattern, and pre-race slope. The B-1 confirmed pattern (壬 × Sasaki, 195.6% recovery) is supported by stable slope times of 54.9→55.2 and an accelerating pre-race slope lap.
2. #8 Mugello (M. Dee) comes from the Fujiwara Hideaki stable with the field’s fastest slope time of 54.5 seconds one week prior. A strong ride on the jockey’s last day of his short-term license. An ideal peaked-readiness pattern.
3. In WHGR terms, #3 Shigeru Kamikaze (+600) and #2 Corlin Carvela (+450) rank highest, but their training metrics are not outstanding. Horses with both strong WHGR and strong training are rare.
4. #10 Rafale d’Or is supported across all three axes: 3rd in pre-race slope + race-week wood 66.6s (fastest) + WHGR +270. A hidden contender.
