Each single featured an original B-side not listed in the title, as well as a cover of a Western artist's song (Louis Armstrong's "What a Wonderful World," Charlie Chaplin's "Smile" and The Beatles' "The Long and Winding Road" respectively).

[11][12] Inspired by the scenery, Kokia chose the themes of life and death, the Earth and about womanhood.

[9][13] Eight of the 14 songs on the album were written about her experiences in Tunisia: "Birth," "Kodoku na Ikimono," "Kono Chikyū ga Marui Okage de," "Love Is Us, Love Is Earth," "Oto no Tabibito," "Real World," "Saishū Jōei" and "Watashi ga Mita Mono.

[9] Recording for the Tunisia-inspired songs from the album began in late December, after Kokia finished her Jū Ni Gatsu no Okurimono tour.

It was based around footage of Kokia in the Tunisian Sahara that was filmed while the photos for the CD jacket were being taken.

[21] Critically, CDJournal described the album as "a work made with all her might, that records her feelings (on life, death, Tunisia, etc) just as they were, with real melodies.
