The best-of albums "Kuuku" and "Uchu" were released simultaneously in 2005 as a joint project between Pony Canyon and Universal Music, and will be released simultaneously by both companies as a two-disc analog record set on colored vinyl.

Based on the concepts of "Kuuku" and "Uchu," this album is a best-of compilation in which drummer Kinichi Mogi (currently with Tokyo Ska Paradise Orchestra) selected tracks across various manufacturers, and there was a strong demand among Fishmans fans for this album to be released on vinyl. The cutting master will be produced by Sterling Sound in New York. The album will be a two-disc colored vinyl set (clear sky blue). Limited Edition.
