Leaves and samara on a Japanese maple (Acer palmatum, unknown cultivar)
Japanese are familiar with special phrases like “Momiji-gari”, which literally means hunting Maple or Maple viewing. Many people visit and enjoy the fall color of wild and natural Japanese Maples in the mountains or fields of Japan. Furthermore, there is a Japanese expression, “Yama ga moeru” which translates to “burning mountain in autumn” because an entire mountain filled with wild Japanese Maples can transform into a fiery crimson red due to the color of the Japanese Maples in the distance.
