Without being too extravagant you can get by with 5000 to 10000 yen per day on lunch and dinner including transportation/subway/rail. That's about $50.00 to $100.00 in American dollars (minimizing taxi usage). Try to avoid the taxi's because that could cost a small fortune, especially in rush hour.
The popular referendum is a device which allows voters to approve or repeal an act of the Legislature. If the Legislature passes a law that voters do not approve of, they may gather signatures to demand a popular vote on the law.
In certain circumstances, a proposed amendment can be submitted to a referendum if it is passed on two separate occasions by only one House of the Parliament. At the referendum the proposed alteration must be approved by a 'double majority'. That is: 1  a national majority of voters in the states and territories. 2  a majority of voters in a majority of the states (i.e. at least four out of six states).
