How have the farmers of japan been able to raise crops in lands that are very mountainous?

Farmers in Japan have adapted to the country's mountainous terrain by utilizing terraced farming, which involves creating flat areas on slopes to cultivate crops effectively. This method helps to maximize arable land and manage water runoff, allowing for efficient irrigation. Additionally, traditional practices and crop selection tailored to the specific microclimates of these regions have enabled successful agriculture despite the challenging landscape.
