(くわ)()
A mulberry tree.
Silkworms eat mulberry leaves.
There is a large mulberry tree in my grandmother's garden.
In the past, mulberry was widely cultivated in this region for silkworm raising.

A tree species historically of enormous economic importance in Japan because its leaves are the only food that silkworms ((かいこ)) will eat. In premodern and modern Japan up through the mid-twentieth century, entire regions were dedicated to 桑畑(くわばたけ) ('mulberry fields') to support the silk industry.

Usage

  • The kanji (くわ) is written with a distinctive three-(また) component on top representing leaves.
  • (くわ) can refer to both the tree itself and, by extension, its leaves and fruit in context.
  • The edible berries are usually called (くわ)() ('mulberry fruit') to distinguish from the tree.
