Check out Webpay for payments in Japan.
Their API was originally supposed to be a clone of the Stripe API, but have gone off with their own API updates based on the JP market.

I know webpay, but it only issues payments in JPY while I charge my customers either in USD or EUR... It's great for Japanese companies targeting the Japanese market, but my customers are mostly in North America and Europe.
