Asagimadara Rest Area
The Chestnut Tiger ("Asagimadara" in Japanese) is a type of migratory butterfly that can travel up to 2,000 kilometers. These creatures with beautiful feathers stop by Himeshima between May and early June every year in search of argusia nectar just before heading further up north.
The following generation of butterflies fly back down to the island in mid October in search of nectar from a plant species called eupatorium fortunei growing on the island.
This makes the Asagimadara Rest Area quite an amazing location for witnessing a rare and mystical natural phenomenon.
