Cloudy Cloud Calculator is a 1997 album by Takako Minekawa. It was released by Emperor Norton Records in the United States. It is Minekawa's fourth album. Cloudy Cloud Calculator was described as one of Minekawa's "finest and most unique [sic] moments", "highly inventive, restrained pop", and "wonderfully cute, all-synthesizer musings." Minekawa played almost every instrument on the album and produced, arranged, wrote, and sang all its songs. Minekawa toured in the United States to support the album. The album Ximer, released in 1998, featured remixes of Cloudy Cloud Calculator by artists including Cornelius, Markus Popp, Sukia, and Michiko Endo (Citrus).
