The grounds of Tokyo's Imperial Palace are home to a little-known garden storing an extraordinary bonsai collection. Overseas guests who visit the Palace may be greeted by masterpieces of the Japanese bonsai art such as the 2-meter high "Neagari-goyo" pine, a 600-year-old juniper, or a 17th century shogun's favorite five-needle pine. Discover the trees -- and their pots of Imari ware and other fine ceramics -- as we explore the unsung cultural ambassadors of the Imperial Household.
