Aogashima Island : A double volcano with distinctive natural surroundings and geography - Part 3

The highlight of Aogashima travel is not only viewing the double volcanic craters, but also hiking inside them. The inside of the large crater is beautifully covered with forest greens, including tropical plant bird’s-nest ferns, rarely seen in Japan. A little like a jungle with no trails, where adventurous hiking can be experienced. However, please remember that hikers must ask someone on the island for a guide. Once you enter the dense forest, you should watch your steps very carefully as the forest is a volcanic caldera formed with bumpy lava rocks, and you could lose your direction very quickly. In fact, even the island people get lost, although they remain calm and soon find their way back. Indeed, they seem always calm, as well as perseverant, cooperative and kind to everybody - that must be the nature of Aogashima people, acquired through living in this very distinct natural environment.

Aogashima is the smallest village in Japan, with a population of 170 people, decreasing little by little. The 25 students at the primary/junior high school, will be leaving the island at the age of fifteen to go to high school on the mainland. Nobody knows when they will be back to Aogashima. What the people sing here in their folklore songs are mostly about stories of leaving the island and parting with their loved ones.

To say good bye, they don’t say words meaning “See you again”, instead, they say Omouwayou, in their dialect, meaning “Thinking of you”.
