From what i know,Japan is a true democracy country now.They have
been through world war 2,they know what will happen if a
dictator from a particular party totally dominate the
politics,or a King who has real power control their parliament.So
right now,their King,like some forumer mention here,dont have any
real power n is like Singapore President.
But Thailand on the other hand,their democracy is on
jeopardy.Their King has considerable power,their former PM Tharsin
get thrown off from his PM seat due to him having dispute with the
King.
