Earlier on Thursday, the Japanese royal couple joined Vietnamese Vice President Vo Thi Anh Xuan to visit the Presidential Palace Historical Site. The trip is part of the Crown Prince's official visit to Vietnam from September 20 to 25.
As pictured, the Crown Prince and the Crown Princess walk with Xuan in her red ao dai on Xoai Street, which connects the Palace with the Stilt House and a fish pond within the site.
