This article, in The Japan Times, is well worth reading for an insight into some of the factors that are going to impact on the actions Abe & his government can take in coming months.

It seems to me that Abe is going to have to restrain his more forthright views on relations with China and on defence (the two are not unrelated), but that his views on what needs to be done for the Japanese economy (and the implications that has for the Yen) are going to be implemented in a very determined manner.

And yet, even this is constrained. While the LDP and New Komeito coalition have a two-thirds majority in the lower house, allowing them to override most Upper House votes, check this out:

The government can nominate candidates for the BOJ governorship and Policy Board seats, but the Diet must endorse them.
In this case, however, the opposition-controlled Upper House could reject the choices with impunity because Lower House overrides don’t apply to BOJ appointments.

There is plenty more of interest in this article.
