I am trying to explain to someone why the Japanese government seems to experience such difficulty, and take such a long time to make decisions. I know this is not unique to Japan, but I'm trying to explain Japan's case anyway. Many times, the laws needed are just not there to help solve the problem. Plus he is at the mercy of the bureaucrats when it comes to interpreting laws which are already on the books. Influential minorities have near-veto power in this process.
Money helps round-off the sharp corners.
The PM has the authority to dissolve the government and call a snap-election. Or this may be forced upon the PM by a vote of no-confidence. Either way, Lower House Dietmembers do not have the job security of fixed terms, and elections are expensive, thereby forcing the PM to be cautious. Would be interested in comments from the collective.
