I'm comparing it to prices in Australia.
The yen has fallen dramatically against the Aussie dollar so I find the cost of living very low in Japan - from food, clothing, local transportation, etc.
For dinner I always eat at an Izakaya pub, which apart from alcohol, serves a large variety of small dishes.
Here's a receipt for a pub meal for 4 people. You can see we had around 19 dishes and 6 drinks - 2 glasses of shochu, 1 large beer, yuzu and honey cocktail, a high ball and an oolong tea. The bill came to 10916 yen (2400 baht, 68 euro, US$71, £56). I would hate to think what such a meal would cost on Australia.
