Lake Koyama stretches to the horizon line beneath blushing cherry blossoms and a sturdy pine. The village of Karo sits on the opposite bank, reduced to small triangles at the foot of the mountain. Once a bay, over time a sandbar formed, separating Lake Koyama from the Sea of Japan. This historical connection to the sea explains the diversity of fish that populate these waters. Today, Inaba Province belongs to eastern Tottori Prefecture.
