Why might Japan impose a tariff on imports of US-produced rice?

Imposing a tariff on imports of US-produced rice is mainly aimed at protecting domestic rice growers from competition. Japan has a long history of rice cultivation, and its agricultural sector is sensitive to foreign competition. By implementing tariffs, the government can increase the cost of imported rice, making it less attractive to consumers compared to domestically produced rice. This protectionist measure helps maintain local agricultural practices, supports the livelihoods of Japanese farmers, and promotes food security by ensuring that domestic production is not undermined by cheaper imports. It reflects a broader policy goal to safeguard local industries from international market pressures and to encourage the consumption of local products.
