"Without You" (ウィズアウト・ユー, Uizuauto Yū) is a single by American singer-songwriter Debbie Gibson. Written by Gibson and Tatsuro Yamashita, the single was released exclusively in Japan in 1990 by Warner Pioneer under the Atlantic label. It was featured in the Japanese drama series Otoko ni Tsuite (About Men) aired on TBS in 1990, and peaked at No. 26 on the Japanese Oricon chart.
A year after its release, Yamashita rewrote the song as "Sayonara Natsu no Hi" (さよなら夏の日, "Goodbye, Summer Day"). Yamashita's interpretation was issued as one of the lead singles for his Artisan album, and gained more commercial success than the original recording.[1]
