Japan can afford to import agricultural products that cannot be grown locally because it has an advanced economy

The correct answer is - industrialized.

Japan is one of the biggest economic players in the global economy, and this is due to their advanced industrialized economy. Japan is a country that lacks natural resources, and it is a country heavily dependent on importing resources, but it is a country that has much more advanced industry that most of the countries in the world, so they import the raw resources, manufacture them, and them sell them for bigger amount of money. This gives them the opportunity to be able to import agricultural products as well, since they have a very strong economy, and do not have enough land for production of the same, they focus on what they see as most suitable and import the things they need from other countries, usually less developed economically.
