Under the Sun is the 16th studio album by Japanese singer-songwriter Yōsui Inoue, released in September 1993.

Two songs "Gogatsu no Wakare" and "Make-Up Shadow" were released as a single prior to the album, and the latter became a massive hit.

"Make-Up Shadow" was featured as the theme song for Subarashikikana Jinsei, a television drama aired on Fuji TV.

The music was composed by Jun Sato (who used the pseudonym Utsuru Ayame), and Inoue wrote the lyrics.

The song became the highest-charting single for Inoue, reaching number-two on the Japanese Oricon Weekly Singles charts, selling in excess of 800,000 copies.
