The friend that I bought the card for thanked me immensely! I live in California and she lives in Tokyo. It allowed her to purchase whatever she wanted and there were no "restrictions" or "returns" normally associated with purchasing clothes or whatever. I use USA Amazon a lot since I live in California and I was very happy to find out there was a JP Amazon! Go job Amazon!!
It is very convenient to buy, send and use a gift card issued by Amazon. What I want to say is it would be better if it can supports multi language - especially Korean, Chinese encodeing. Currently, the message left will be broken if it is written in other Asian language but not Japanese. You know, there are lots foreigners in Japan and many of them are also using Amazon.co.jp a lot.
