If you're shopping with us from outside Japan, we're afraid "Bill Me Later" (or, "PayPal Credit") is unfortunately not an available PayPal payment option.
This is because we are in Japan, and our prices are in Japanese yen. We charge you in yen, and the conversion to your local currency is done by PayPal. We're very sorry, but we aren't able to accept payment in a currency other than Japanese yen. As a result, "Bill Me Later" is not an available PayPal payment option if shopping with us from outside Japan.
