Yes, in Japan, particularly in regions like Fukui Prefecture where Fudai is located, it is common for homes and businesses to be built in valleys between mountains. This practice is influenced by various factors, including geography, climate, and historical development patterns.
Building in valleys can provide relatively flat land, which is conducive for construction and agriculture. Additionally, valleys may offer protection from harsh weather conditions, such as strong winds, and can provide access to resources like water from rivers and streams. However, such areas may also be susceptible to natural hazards, such as flooding and landslides, which are considerations in planning and construction.
Overall, the choice of location often reflects a balance of these factors, alongside cultural and historical influences.
