Erosion control forests in Enshu Nada run from the south coast of Lake Hamana to the east of Omaezaki for about 100km, but their depth is only 200 m at most. I often walk back and forth in the 200m-wide forest, and already two years have passed since I started doing this.
There is a word "Ubusuna", and its characters mean the land (sand) that gives birth. Some people think it originally meant "sand" rather than "land". The birth of human beings is closely related to the boundary between the sea and land. The evolution of fish to amphibians took place on the coast. Japanese mythology describes a story about maternity houses that were built on beaches, which was also an interesting anecdote about the birth of humans. The maternity houses remained in various parts of Japan until the Meiji era. Like the maternity houses on the beaches, in the maternity houses in villages deep in the mountains, there was always white, clean sand laid on the floor. On the north coast of Lake Hamana, there is only one beautiful maternity house with a thatched roof remaining.
Forests on beaches were created by humans by planting trees, but the dense forests where grass on the ground is overgrown looks like it is refusing entry to humans. However, even in such places, if I remove only a few dead branches and fallen leaves, I can immediately find white sand. Long ago, humans came up from the ocean to the land through beaches during the process of evolution. Beaches are "places" that are deeply related to the birth of humans, but are also "places" of death. Numerous people lose themselves in this quasi forest in search of a place to die. The life and death of humans is silently repeated between the sea and land.
