Kamakawiwoʻole was known for promoting Hawaiian rights and Hawaiian independence, both through his lyrics, which often stated the case for independence directly, and his life. For Example, the lyric in his song "Hawaiʻi '78": "The life of this land is the life of the people/and that to care for the land (malama ʻāina) is to care for the Hawaiian culture", is a statement that many consider to summarise his Hawaiian ideals. The state motto of Hawaiʻi is a recurring line in the song and encompasses the meaning of Iz's message: "Ua Mau ke Ea o ka ʻĀina i ka Pono" (proclaimed by King Kamehameha III when Hawaiʻi regained sovereignty in 1843. It can be roughly translated as: "The life of the land is perpetuated in righteousness").
Kamakawiwoʻole was born at Kuakini Medical Center in Honolulu to Henry "Hank" Kaleialoha Naniwa Kamakawiwoʻole, Jr. and Evangeline "Angie" Leinani Kamakawiwoʻole. The notable Hawaiian musician Moe Keale was his uncle and a major musical influence. He was raised in the community of Kaimuki, where his parents had met and married. He began playing music with his older brother Skippy and cousin Allen Thornton at the age of 11, being exposed to the music of Hawaiian entertainers of the time such as Peter Moon, Palani Vaughn and Don Ho, who frequented the establishment where Kamakawiwoʻole's parents worked. Hawaiian musician Del Beazley spoke of the first time he heard Israel perform, when, while playing for a graduation party, the whole room fell silent on hearing him sing. Israel continued his path as his brother Skippy entered the Army in 1971 and cousin Allen parted ways in 1976 for the mainland.
The Makaha Sons of Niʻihau recorded No Kristo in 1976 and released four more albums, including Kahea O Keale, Keala, Makaha Sons of Niʻihau and Mahalo Ke Akua. In 1982, Kamakawiwoʻole's brother, Skippy, died at age 28 of a heart attack related to obesity. In that same year, Kamakawiwoʻole married his childhood sweetheart Marlene. Soon after, they had a daughter whom they named Ceslieanne "Wehi" (born in c. 1983).
The group became Hawaii's most popular contemporary traditional group with breakout albums 1984's Puana Hou Me Ke Aloha and its follow-up, 1986's Hoʻola. Kamakawiwoʻole's last recorded album with the group was 1991's Hoʻoluana. It remains the group's top-selling CD.
His voice became famous outside Hawaii when his album Facing Future was released in 1993. His medley of "Somewhere Over the Rainbow/What a Wonderful World" was released on his albums Ka ʻAnoʻi and Facing Future. It was subsequently featured in several films, television programs, and television commercials.

The Hawaii state flag flew at half-staff on July 10, 1997, the day of Kamakawiwoʻole's funeral. His koa wood coffin lay in state at the state capitol building in Honolulu. He was the third person in Hawaiian history to be awarded this honor, and the only one who was not a government official. Approximately ten thousand people attended the funeral. Thousands of fans gathered as his ashes were scattered into the Pacific Ocean at Mākua Beach on July 12, 1997. According to witnesses, many people on land commemorated him by honking their car and truck horns on all Hawaiian highways that day. Scenes from the funeral and scattering of Kamakawiwoʻole's ashes were featured in official music videos of "Over the Rainbow" released posthumously by Mountain Apple Company. As of March 2018, the two videos as featured on YouTube have collectively received over 500 million views.
