The Japanese ambassador gave a 300-year-old stone lantern to the city of Washington to commemorate the signing of the 1854 Japan-US Treaty of Amity and Friendship by Commodore Matthew C. Perry. For a number of years, the lighting of this lantern formally opened the Festival. Three years later, the president of The Pearl Company started by Mikimoto Kōkichi donated the Mikimoto Pearl Crown. Containing more than of gold and 1,585 pearls, the crown is used at the coronation of the Festival Queen at the Grand Ball. The next year, the Mayor of Yokohama gifted a stone pagoda to the City to "symbolize the spirit of friendship between the United States of America manifested in the Treaty of Peace, Amity and Commerce signed at Yokohama on March 31, 1854."
