With the full moon on a long autumn night

The Japanese Pampas Grass is one of the seven grasses of autumn and is characterized by the broom-like white ears that appear at the tips of its stems in autumn. The ears appear white because of the white hairs growing on the shoots, which allow the seeds to fly far in the wind.
Japanese Pumpas Grass and other grass plants that contain oil in their stems are called "Kaya", and because of their high water resistance, they were used for roofs and rain gear, livestock feed, and fertilizers, and there used to be a wide area of Kaya fields around rural villages. Although the number of Kaya fields has gradually decreased with modernization, traces of it can still be found in place names and surnames.
From the perspective of land succession, the Japanese Pampas Grass is considered to be a plant that grows almost at the final stage of grasslands, and if left as it is, trees will eventually invade and transform the land into a forest. As a result, much of the Kaya fields have become forest.

In Japan, there is a custom of decorating Japanese Pampas Grass and rice dumplings on the full moon day of September. It is a typical autumn scene.
