After the f ukushima disaster, kiko became very concerned about her country’s dependence on nuclear energy. why does japan resort to nuclear energy?

1)government policy

2) import tariffs

3)no native fossil fuel deposits

4)cheapest fuel source available

Option 3,  no native fossil fuel deposits

Explanation:

Japan has extreme resource crunches and therefore it has to rely on nuclear energy resources for energy production.  

This nation has a very little coal reserve and that too is depleting at a fast rate.  There is no natural oil and gas reserve in the country.  

Since the energy demand of Japan grew extensively, therefore in order to meet its rising demand it was required to produce energy at a large rate and hence it relied on nuclear resources.

Hence, option 3 no native fossil fuel deposits
