From there we can find the USD-JPY exchange rate.
On January 3, 2005 the rate was: 1 USD = 102.6694 JPY
On January 2, 2006 the rate was: 1 USD = 117.9245 JPY

2. The dollar appreciated against the yen. With the values above we can use the formula

Appreciation (or Depreciation) = (Change in Exchange Rate / Original Rate) * 100

Plugging in the values we see that

Appreciation = (15.2551 / 102.6694) * 100 = 14.858%
