About this extension

This extension automatically converts Japanese Yen prices to US Dollars on Amazon Japan (amazon.co.jp). Features include:

- Real-time currency conversion using up-to-date exchange rates
- Toggle between showing both currencies (¥1000 ($6.37)) or USD only ($6.37)
- Converts all prices on the page, including search results and product pages
- Updates automatically when new content loads
- Simple one-click toggle via the toolbar icon
- Works with all Amazon Japan pages

Some products require you to select a size, length, or amount before it will display the price. This is intended, as the "final price" is not shown until an amount is selected.

Developer comments

The extension uses the free exchangerate-api.com service for currency conversion rates. The extension only runs on amazon.co.jp domains and only modifies price displays. No user data is collected or stored beyond display preferences.
