Amami Oshima Islands in Kagoshima Prefecture receives one of the largest amounts of rain in Japan. Its rainy season, which runs from May through June, in particular, provides enough water to sustain its lush nature, including rare species of plants and animals, all year round. In this episode of Journeys in Japan, outdoor writer from Sweden Janni Olsson enjoys Amami's rainy season as she engages in activities not available elsewhere and learns about the island's culture.
