# List Japan Rail Lines

`GET /japan/rail/lines`

Return a GeoJSON FeatureCollection of Shinkansen lines.

Each feature's `geometry` is a MultiLineString in WGS84 (the underlying
PostGIS column is geometry(MultiLineString, 4326)). Per-feature
properties carry the names + operator labels the FE needs to label
each line. Brand COLORS live on the FE side as a static map (see
`program/app/japan/rail-line-colors.ts`) — they're presentation, not
data, and don't need a DB round-trip.

Cache headers match `japan_places`: short browser TTL, longer at the
edge — data only changes when the loader script runs.

## Response `200`
