The verified update
Yes. Official feature text connects nautical charts with reaching remote islands that contain rare collectibles and animals.
This briefing isolates one part of the public record so that a player can act on the confirmed detail without mistaking a broad trailer, preorder listing, or product page for a complete specification.
What the source establishes
- Remote islands are part of the exploration loop.
- Nautical charts are the named discovery tool.
- The number of charts, islands, and exact acquisition steps are not published.
Why it matters now
Prelaunch guidance should focus on the expedition loop rather than inventing chart coordinates.
For editorial tracking, this topic should be reviewed again when Natsume publishes another game-specific release, when a verified platform store exposes new metadata, or when launch-day testing can answer the remaining operational question.
What this update does not establish
The relationship between charts and islands is confirmed, but a walkthrough needs real map locations and tested requirements.
No unannounced feature, value, route, schedule, performance target, item table, or story outcome has been inferred. The distinction is important because the game is still unreleased.
