The family departed from Tokyo’s Haneda Airport on Friday. Prince Hisahito, who will one day likely become Emperor of Japan, has gotten so tall! He turns thirteen in September.

On Monday, the family headed for one of the most recognizable venues in Bhutan: the national archery stadium in Thimphu.

Kiko wore a long, traditional Bhutanese-style skirt for the visit. (Remember when the Duchess of Cambridge sported a similar one a few years ago?)

She wore pearl earrings and a lovely pearl station necklace with her ensemble. She also wore the same attire and jewels on Monday for a visit to the National Textile Museum, where they were accompanied by Queen Mother Sangay Choden and Princess Dechen Yangzom Wangchuck.
