Japanese Election

It had* been for about three years since the change of ruling parties in Japanese Gorverment.Yesterday, 16th December, a general election was held.

Yesterday, there was a general election is Japan.  It's* been three years since power changed hands in Japan.

*Since the results of the election are still relevant/immediate, I'm using HAS BEEN rather than HAD BEEN.  As well, in the news genre, stories are often told in this tense to convey the sense of connection of the events being reported to the present moment (that's why it's news, right, because it usually *just* happened) compared to HAD BEEN, which is normally used to sequence completed actions in the past. 

The Liberal Democratic Party(LDP) and New Komeito got two-thirds of the Diet seats, marking the end of the Democratic Party of Japan(DPJ)'s three years in power.

It seems that the proposed policy of scaling back nuclear power generation / reduding Japan's dependence on nucleur energy haswas not been supported by voters.

The most needed policy Voters were looking for candidaites with platforms that would make a strong economy.   As well, a large portion (or, a large proportion) of the voters has wanted a new government to resolve the matter of territorial disputes among the neighboring countries.

In my opinion, I'm disappointed about with the result because I've been supporting policies aimed at ending the use of nuclear power. 

Anyway, (or, In any case...)we hope that a new government will figure out the these** severe matters (serious issues) clearly step by step with a strong faith.

** using the pronoun "these" rather than the article "the" is a good way to have tighter referencing (i.e.less ambiguity about what words are pointing to which ideas).  Clear referencing is one of the characteristics of more advanced writers. Using "the' is "correct", just less clear.  Hope this makes sense.

with a strong faith ... not sure what you mean here.  I percieve some incongruency here because we don't often consider that problems or issues are resolved with faith.  It's not a matter or correct ot not correct, it's matter of translating the original idea differently???

I think an approximation to the Japanese might be to say that these very serious national problems should be tackled with everyone putting forth their best effort?
