Binary options on USD / JPY
USD/JPY is the dollar against the yen. It often wakes up when Tokyo overlaps New York. The payout is 84%, below the euro and the pound.
The yen is the currency of Japan. Buyers often move into it when other markets are uneasy, so the dollar rate listens to Tokyo and to US rates. The Bank of Japan kept money very cheap for years, and the pair still reflects that.
