The yen continued to trade lower against the dollar in Asia Tuesday, as the Greenback was again back in vogue. With little fresh news in Asian trading hours, the dollar continued its recent resurgence. The yen slipped to Y122.58 against the dollar and Y109.30 against the euro, before Japanese corporate sellers capped rises. The euro could not regain any ground against the dollar, ending little changed from late New York levels at $0.8915.
