The verified update
Players obtain nautical charts to locate remote islands, treasure hunt, and befriend rare animals not found on the mainland.
The evidence was checked against Natsume title announcement and is current to 2026-07-31. The date attached to the underlying source is 2026-03-11.
What the source establishes
- Charts are the named discovery tool
- islands contain treasure opportunities
- some animals are island-specific.
Why it matters
Build the future walkthrough around verified chart acquisition and island access steps after launch.
That distinction helps players make a release, platform, route, story, or purchase decision using the narrow fact actually supported by the source.
The remaining boundary
The number of charts, islands, treasures, and taming requirements has not been published.
Any later change should be dated and linked to a new first-party notice rather than silently overwriting the historical source.
