This is a steeplechase G1 race (Nakayama Grand Jump). The WHGR system was developed and validated on flat racing. Its application to steeplechase races has not yet been validated. The evaluations below are reference values based solely on WHGR indicators plus hillside and woodchip training data, and do not account for jumping technique, jumping form history, or suitability to the 4260m ultra-long distance. Please use these alongside steeplechase-specific factors when making any betting decisions.

No horse satisfies both combined WHGR ★★ and training ★★/★★★. The top-voltage pair have limited flat-training data, while those with confirmed training carry modest indicators — the steeplechase-specific scarcity of flat-training data is the judgment wall here.

We present the top B+ tier below, split by strength type (indicator-led vs. training-led), ordered by combined WHGR.

Horse WHGR +80, jockey +150 — balanced split. Flat-training data this week is thin, but last week’s woodchip 3F in 37.6s is on record. Takada is a steeplechase veteran; Tsujino’s Ritto shipper brings travel intent.

Horse WHGR +200, jockey +0. Onodera is the steeplechase-only specialist, Iizuka a Miho-based trainer with a local-track advantage. Flat-training data is limited but indicator support is clear.

Last week’s woodchip 6F in 36.2s (absolute time) followed by this week’s relaxed work — the completed-preparation pattern. Mori is the dedicated steeplechase jockey; Takahashi’s Miho stable brings home-track advantage.

Woodchip maintenance type ★★★ — consistent gallops week over week. Ishigami is a top steeplechase rider; reliable baseline preparation.
