At a height of 1,982 meters, Mt. Ishizuchi is the tallest peak in western Japan. It takes about three and a half hours to the summit if you board the ropeway for part of the journey. During the fall season many people hike up to view the autumn leaves. Mt. Ishizuchi has been revered as sacred since ancient times. Mountain ascetics worship here to this day. It is also called "the mountain of life" by neighboring residents. At the foot of the mountain lies Saijo City, where its plains' annual rainfall registers only 1,400 millimeters. But the rainfall on Mt. Ishizuchi is two to three times that amount, most of which flows into the city. The rich groundwater is said to rank among the tastiest in Japan. There are many public water fountains in Saijo.

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.
