The verified update
Yes. Natsume says remote islands contain rare animals that players will not find 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
- Nautical charts locate the islands
- animals can be befriended
- island exploration also includes treasure hunting.
Why it matters
Treat island exclusivity as confirmed while keeping species-level pages out of the sitemap until evidence exists.
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
No species list, spawn schedule, or taming requirement is published.
Any later change should be dated and linked to a new first-party notice rather than silently overwriting the historical source.
