Tsuyoshi Nagabuchi (長渕 剛, Nagabuchi Tsuyoshi, born September 7, 1956) is a Japanese singer-songwriter, actor, poet, and human-rights advocate, who is a prominent figure in Japanese popular music.

Nagabuchi favored popular Japanese folk singers such as Takuro Yoshida, Ryo Kagawa, Masato Tomobe and Kenji Endo.

Around 1974, he formed a folk duo called "Takeshi and Tsuyoshi" and gained experience as a performer.

In 1975, he entered Kyushu Sangyo University but eventually dropped out and chose the career of show business.

The next year, this song was released as his first single from JVC Victor Records (credited as Go Nagabuchi) and failed to chart.

The approach of "Ame no Arashiyama" arranged by Motoki Funayama was enka-style and Nagabuchi wanted to avoid such a conservative style.

After the failed debut song, he contracted with Toshiba EMI and attempted to break onto the music scene again.

In 1980, Nagabuchi released another well-known Japanese folk song classic, "Kanpai," which he wrote for his friend's wedding.

"Goodbye Seishun" in autumn of 1983, his first smash-hit single since "Junko," was written with Yasushi Akimoto for the TV drama series he starred in.

In the 37th film of the movie series Otoko wa Tsurai yo in 1986, he acted with his future wife Etsuko Shihomi.
