"Earthly Stars (Unsung Heroes)" (地上の星, Chijō no Hoshi) is a song that Japanese musician Miyuki Nakajima composed and recorded for the country's acclaimed television documentary program Project X -Chōsenshatachi-, which aired on NHK during the first half of the 2000s.

Double A-Side single "Earthly Stars (Unsung Heroes)"/"Headlight, Taillight" is the first release under the record label, Yamaha Music Communications, which was newly founded in 2000.

Akira Imai, a producer of the television program decided to ask Nakajima to write theme songs, because he was moved by lyrics of her 1998 smash hit "Another Name for Life".

On 31 December 2002, Nakajima made her appearance on the annual NHK music program Kōhaku Uta Gassen where she performed "Earthly Stars" from the tunnel in Kurobe dam, Toyama Prefecture.

All songs written and composed by Miyuki Nakajima, arranged by Ichizo Seo Footnotes: Until expansion of the hit parade in December 2002, Oricon provided only the top-100 sales charts in general (except a more detailed magazine especially published for the music industry called Original Confidence)
