Amazon Coins (not to be confused with Amazon’s recently launched store for collectable coins) is expanding into Japan and Australia.

The virtual currency was launched last year, and the company says customers have already spent hundreds of millions of Amazon Coins. Amazon’s Mike Hines writes in a blog post:

Now customers in Japan and Australia can use Amazon Coins on apps, games, and in-app items from their Kindle Fire, Android phone or tablet, and on amazon.co.jp and amazon.com.au. Customers can enjoy apps and games for less by purchasing Amazon Coins, and the more they buy, the greater the discount.

For a limited time, every Kindle Fire owner in Japan and Australia will find 500 Yen/$5.00 AUD worth of free coins deposited into their Amazon Account. And as an additional incentive, customers can also purchase coins in bulk and receive a discount of up to 20% to spend on apps and games in the Amazon Android Appstore (regular discount is 10% off apps and games).

Amazon Coins enable users to save up to 10% on app purchases. According to Amazon, many developers count the currency as being responsible for the majority of their revenue.
