Yakushima holds the distinction of being Japan's first UNESCO World Heritage site, renowned for its ancient cedar forests containing trees over 1,000 years old called yakusugi. The island inspired Studio Ghibli's "Princess Mononoke" and hosts unique wildlife including approximately 7,000 wild Yakuzaru monkeys and 7,000 Yakushika deer found nowhere else. The Tourist Center serves as an essential first stop because staff provide crucial guidance about the island's extreme weather variations, from coastal areas receiving 4,000mm of annual rainfall to mountain peaks experiencing over 10,000mm yearly, ensuring visitors are properly prepared for their adventures.
