I'm not going to try and untangle the complicate political system for you or try and explain why we've had 31 prime ministers since the war ended but look at this quote from the Japan Times:
Kamei, who left ruling coalition member Kokumin Shinto (People's New Party) in April to protest the consumption tax hike, announced the formation of his new party Monday, along with former farm minister and DPJ defector Masahiko Yamada.
Did you follow that?
No wonder it's hard to keep the parties policies straight when making a decision who to vote for, around here it's hard to keep the party members straight!
Seriously though, is there any other country with such a blase approach to party politics?
It really annoys me as I think it leads to voter apathy and I don't think that's good for anyone.
Then again, despite living, working, owning property and raising children here I don't even get to vote so bed-swapping politicians are the least of my political worries, hey?
