Taiga drama (大河ドラマ Taiga dorama?, "Big River Drama") is the name NHK gives to the annual, year-long historical fiction television drama series it broadcasts in Japan. Beginning in 1963 with the black-and-white Hana no Shōgai, starring kabuki actor Onoe Shoroku II and Takarazuka star Awashima Chikage, the network has hired a producer, director, writer, music director, and actors for the series. The 45-minute show airs on the NHK General TV network every Sunday at 20:00, with rebroadcasts on Saturdays at 13:05. NHK BS Premium and NHK World Premium broadcasts are also available.
Saka no Ue no Kumo was originally set for a 2006 broadcast as "21st Century Taiga Drama". However, the scriptwriter of the series committed suicide, causing a delay in production. The series was aired as "NHK Special Drama" in three parts, each part airing from late November to late December of each year.
