This rice-straw wrapper protects the bark of a tree in Hama Rikyu Koen, the Detached Palace Garden. Originally a hunting preserve for the Tokugawa Shogunate, Hama Rikyu is one of Tokyo's most opulent gardens, located in the Ginza district on an island connected to the mainland by the Nanmon Bridge which arches over an ancient walled moat. The garden features exquisite topiary, moon-watching pavilions and a salt-water tide pool.
