Takeshi Kamada, Credit Suisse $($Tokyo$),$ observes that the $/$$ spot rate has been holding steady, and both dollar and yen interest rates have remained relatively fixed over the past week. Takeshi wonders if he should try an uncovered interest arbitrage $($UIA$)$ and thereby save the cost of the forward cover. Many of Takeshi's research associates$-$ and their computer models$-$ are predicting the spot rate to remain close to $/$$ $118\mathrm{.}00$ for the coming year. Using the data below, calculate the UIA profit potential $($in yen$).($round to two decimal places$).$

Arbitrage funds available $$5,000,000$ or its Yen equivalent
