Yes, mountainous areas in Japan do make farming difficult. The steep slopes and rugged terrain in mountainous regions can limit the amount of arable land available for agriculture. Additionally, the soil in mountainous areas may be less fertile and more prone to erosion, making it challenging to grow crops. Farmers in Japan have devised ways to terrace the land on mountainsides to create flat fields for cultivation, but this can be labor-intensive and costly. Overall, the topography of Japan's mountainous areas presents challenges for agriculture and has influenced the types of crops that can be grown in these regions.
