今後 Roadmap & releases
Where the data can still go, and how the atlas has grown to here. The plan and the changelog, in one place.
What's possible with deeper data
Where the data can still go. Each row is a capability - shipped, available-but-untapped, or backlog - plus the analysis it unlocks.
| Capability | Status | What it unlocks |
|---|---|---|
| Per-rikishi profiles | Shipped — /rikishi/[id] ×558 + directory | Career rank arc, head-to-head, kimarite preferences, honors — from the cached 1958-present banzuke records. Opponent-quality-adjusted win % still open. |
| Wrestler comparison | Shipped — /rikishi/[a]/vs/[b] ×2,701 + /compare picker | Side-by-side dossier for any two Ozeki- or Yokozuna-ranked wrestlers: head-to-head with per-direction kimarite, overlaid career arcs, full-career fighting-style mix, common opponents. |
| Per-heya (stable) profiles | Shipped — /heya/[slug] ×69 + directory | Full roster, all-time yusho/sansho/yokozuna output, active span. Latest-recorded stable per wrestler (no per-basho lineage — stated on-page). |
| Per-shusshin (origin) pages | Shipped — /origin/[slug] ×61 + directory | Wrestlers by prefecture / country, foreign-born waves over time |
| Per-kimarite pages | Shipped — /kimarite/[technique] ×84 + directory | Per-technique frequency + era comparison back to 1958. Shared kimarite definitions lib already built. |
| Per-basho pages | Shipped — /basho/[id] ×404 + directory | Single-tournament deep dives — day-by-day flow, kimarite mix, attendance |
| Per-kabu (elder name) pages | Shipped — /kabu/[slug] ×104 + directory | Elder-stock lineage, holder history, ichimon × status matrix (SUMO-57) |
Per-bout opponentID (cached) | Lifted + powering head-to-head (SUMO-21) | H2H matrices, rivalry timelines — now live on every profile |
| Sansho (special prizes) | Lifted + surfaced (SUMO-21) | On profile + heya dossiers; all-time sansho trends still open |
/basho/<YYYYMM>/torikumi/<Div>/<day> | Available, not adopted | Tomorrow's-matchups widget during a live basho |
| Tier 2 historical (1909-1957, sumodb scrape) | Backlog | Pre-war yokozuna lineage, kimarite trends through the war years |
| Tier 3 historical (pre-1958 yokozuna lineage) | Lineage shipped | Yokozuna reigns Gantt extended to Tanikaze (1789) via Wikipedia; banzuke rankings still open |
