The mouth of the World Tree, all it does is chat and talk.

None
To chat or talk with the World Tree, just head over to Shaman Bay (しゃべ).
An update is needed before you can continue but you have more than one WaniKani tab open.
Finish up what ever you are doing on the other tab(s), then close them to continue.
The update will complete automatically once the other tab(s) are closed.
