What factors contribute to Japan's dependence on trade and fishing?

Question:

Answer:

Are you talking about Japan lacks natural resources line of thought?
Then 98% of oil she consumes comes from foreign countries just because there is not a large oil source domestically.
But as rabbiton wrote Japan has rich sea resources as well as some minerals such as whattyamacallit i forgot the english name. Also the soil in Japan is rich in nutrients and water is plenty, so Japan is suitable for cultivation.
Fishing is important just because Japan consists of small islands and there are lots of fish in the sea.

As he or she wrote Japan's economy does not depend on her exports.
This is an English website that tells you the proportions of exports in GDPs of various countries:

Japan's rank in this list is 171. So it's in near the bottom. The proportions of exports of various countries in their GDPs are: 10%(the US), 13%(Japan), 26%(the UK), 26%(Italy), 40%(Germany), 37%(China), 42.5%(South Korea). Which shows that the proportion of Japan's exports in her GDP is the second lowest in G8.
Simply speaking, Japan's exports is probably not as import for her economy as Germany's or Italy's exports are import for them. So people in Japan says that Japan's "dependence on foreign demands" is low. Whatever this means.

But then again, Japan doesn't not produce oil so Japan "depends" on imports. Well if you have watched Godfather II, you should know that(there's a reference to this at the end of the movie).
