Asukayama, Japan's first public park, was opened in 1737 as an act of piety by the shogun Yoshimune (1684–1751), who ordered the planting of hundreds of cherry trees there to create a pleasant place for popular outings. Into the distance extends a delicate green haze, spreading out to a gray-wash pattern of rice paddies and a blue line at the horizon suggesting the Tone River. Hovering above this all, streaked with thin bands of clouds, is the accentuated outline of Mount Tsukuba.
