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.

Thus, a reconciliation bill needs only a simple majority to be approved, not the supermajority of 60 votes required to overcome a filibuster.
