Japan
Well, Kyushu isn't for sure.
I'm British and find Japan generally cheaper than Britain.
For example:
Average meal = 1,000yen or less (5 pounds) - it's very easy to find good simple food for 600 yen.
Average drink price = 500 - 600 yen (2.50 - 3 pounds)
Hotel prices = cheap 3,500 / average business hotel 5,500
Clothes and other stuff seems much cheaper than Britain.
Transport - shinkansen pricey but other trains much cheaper than Britain.
Fruit and veg can be bizarrely expensive, but depends on where you shop.
Maybe central Tokyo is pricy, but everywhere else is as above.
