Yen backs off four-week high against dollar

Dollar tilted higher in Asian trade away from August 22 lows versus yen, amid a lack of data from Japan today and ahead of US housing data. 

As of 05:54 GMT, USD/JPY rose 0.11% to 111.97, with an intraday high at 112.01, and a low at 111.67. 

Investors await Bank of Japan's policy meeting later this week, expected to introduce more flexibility in the monetary policy and maintain the interest rates at minus 0.10% for the 16th meeting in a row. 

Awaited US data today include an index tracking the housing sector, expected to increase to 66 from 67 in August, in addition to housing starts and building permits data.
