The geographic feature that caused the Japanese to become dependent on other cultures for food is mountains.

Explanation:

To understand why mountains led to Japan's dependence on other cultures for food, we need to examine the impact of these geographical features on agricultural practices.

1. Terrain: Japan is a mountainous country, with rugged and steep terrain making up around 70% of its land area. This topography poses challenges for large-scale farming, as it limits the amount of arable flat land available for cultivation.

2. Limited arable land: Due to the presence of mountains, Japan has relatively small areas of flat, fertile plains suitable for agriculture. These plains are mainly found along the coastlines and some river valleys. Consequently, the overall land area available for agricultural production is relatively limited.

3. Intensive land usage: The scarcity of flat land for cultivation has led to a widespread practice of terraced farming in Japan. Terracing involves cutting steps or terraces into the slopes of mountains to create flat areas for farming. While this technique maximizes land use efficiency, it does not provide enough agricultural output to sustain the population.

4. Limited self-sufficiency: The combination of limited arable land and a growing population has made it difficult for Japan to be self-sufficient in terms of food production. As a result, Japan has historically relied on trade with other cultures to meet its food requirements, especially for staple crops like rice and wheat.

Therefore, it can be concluded that the mountainous terrain in Japan has caused them to depend on other cultures for food due to the scarcity of arable land and limited agricultural output.
