[100, 200, 300, 400, 500, 600, 700 ,800, 900]
This kinda money'll probably buy you a meal at a fast food joint or a neat little toy from some vending machine, but knowing the average person traveling to Japan what you desire will undoubtedly climb into the 1000+ or even 10,000+ yen range. Here are the kind of numbers you'll most likely come across as you roam around the various stores.
[1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000]
This is the most common range of numbers you'll see when you're shopping around the cities, and the only things I know more expensive than 9000 are specialty goods, collectors editions of stuff and so on(the stuff I know a lot of you want, but might not be able to afford without donating a kidney or first born child). Now, before we go higher up the ranks of spending, I think it's time for a bit of a break to review the money system, as well as how to recite our larger chunks of change.
