V-Preca (Visa Prepaid Card)

Hi Jehye.

I am not absolutely sure about V-Preca because I havent heard of it before. But as far as I ca see, its just a regulr visa card so you should have no problem using it anywhere online where they accept visa cards.

About amazon Japan:
Here's the Japanese page containing info on all accepted payment types in Amazon Japan (I usually use cash on delivery or delivery at the kombini and pay at the kombini with any accepted means of payment there).

You should translate the info. if you are using google chrome, jsut right click any blank space in the page and select "translate page to english"(its the last option).

Here's a translation of the page I jsut sent you above:
