Roei no Uta (露営の歌?, Song of the Camp) is a Japanese gunka song composed by Yūji Koseki with lyrics by Kīchirō Yabūchi. The song was released by Nippon Columbia in October 1938.
In the wake of the outbreak of the Second Sino-Japanese War in July 1937, demand for patriotic songs to boost public and military morale swelled in Japan. Newspapers regularly held competitions calling for submissions from the public of songs and song lyrics. The lyrics for Roei no Uta were chosen in such a fashion, after a contest jointly held by the Tokyo Nichi Nichi Shimbun and Osaka Mainichi Shimbun. The jury, which consisted of luminaries such as the writer Kan Kikuchi and the poet Hakushū Kitahara, awarded Kīchirō Yabūchi's Roei no Uta as the winning entry. The 28-year-old composer Yūji Koseki was chosen to set the lyrics to music.
Nippon Columbia recorded the song soon after with singers Tadaharu Nakano, Akira Matsudaira, Noboru Kirishima, Hisao Itō, and Akira Sasaki performing, backed by the Nippon Columbia house orchestra under the direction of the composer. The song, originally the B-side to the Shingun no Uta (進軍の歌?, Song of the Advance) which was performed by the Toyama Military Academy's band and male chorus, quickly eclipsed its discmate in popularity, eventually selling in excess of 600,000 copies.
