PV International Desk : Prince Akishino, the second son of Japan’s Emperor Akihito, and his wife, Princess Kiko, are making their first official visit together to the U.S.

The Japanese royal couple is in Hawaii this week as part of a yearlong celebration of the 150th anniversary of the first Japanese immigrants arriving in the islands.

Akishino and Kiko laid a white wreath with peace lilies on Monday at the National Cemetery of the Pacific in remembrance of soldiers who died during World War II and the Vietnam War.

The couple was accompanied by cemetery director James Horton, and Adm. Phil Davidson, who became last week the commander of U.S. Indo-Pacific Command in Hawaii, the American military’s Pacific headquarters.

They also laid a second white wreath at Ehime Maru Memorial in downtown Honolulu’s Kakaako Waterfront Park, which commemorates Japanese lives lost when a U.S. submarine collided with a Japanese ship in 2001.

During their visit, the royal couple will also plant a tree in Thomas Square, visit the Japanese Cultural Center of Hawaii, and attend dinner with Gov. David Ige at his residence, Washington Place.

The Hawaiian-inspired menu features local ingredients with Japanese touches, such as oysters from Kualoa Farm served with yuzukosho, a Japanese condiment typically made of chilis, yuzu peel and salt.
