you're borrowing YEN and selling USD, YEN interest rate (what you pay) has to be lower than the USD interest rate (what you get) in order to make a risk-free profit.

(direct quote)
earning risk-free profit is possible buy borrowing yen, thus assuming borrowing 1 jpy for time period t, S (1+ R usd)^t - F (1 + R jpy)^t > 0
(unannualized) hedged japanese interest (relative) return = F (1+R jpy)^t / S < (1+ R usd)^t
(annualized) hedged jpy return = F (1+R jpy) / S - 1 < R usd
