Kilauea

Kilauea is the "Land of Fire" where Musshuru was exiled to after he released a massive wave of poisonous spores that annihilated a massive portion of Drum Kingdom ten years ago. The land is most likely on fire, as he was sent here to neutralize the fire-weak spores. The Land of Fire is only mentioned in the ninth movie, and has not made an actual appearance in the series.
