Aiba began his career in the entertainment industry when he joined the Japanese talent agency Johnny & Associates in 1996 at the age of 13. Prior to his debut as a singer with Arashi in 1999, Aiba started an acting career when he was cast as the lead role of Gordie for the stage play Stand by Me, which was based on the film of the same name. About five years after his debut as a singer with Arashi in 1999, he became one of the co-hosts of the variety show Tensai Shimura Dōbutsuen (天才！志村どうぶつ園 Genius! Shimura Zoo) in 2004, making him the first member of Arashi to regularly participate in a variety show not primarily hosted by Arashi.
Aiba was born in Hanamigawa, Chiba as the first child of his family. He has a younger brother who is four years younger. Aiba was raised by his grandparents until he was four years old because his parents were busy running their newly opened Chinese cuisine restaurant then.
Prior to joining Johnny & Associates, Aiba watched a program called Love Love SMAP (愛ラブSMAP Ai Rabu SMAP) and saw SMAP playing basketball on television. Wanting to play basketball with them, he sent in the application to join the talent agency himself, without exactly knowing what the agency specialized in until the day of auditions. Aiba became a Johnny's Jr. in August 1996 at the age of 13.
In collaboration with the other members, he has written the lyrics to "Fight Song" and "5x10". For his solo song "Hello Goodbye", Aiba played the harmonica portion of the song throughout Arashi's Arashi Marks 2008 Dream-A-Live and Arashi Marks Arashi Around Asia 2008 concert tours. Aiba also used to play the saxophone; however, due to the collapse of one of his lungs in 2002, he was forced to stop playing due to the operation he had to undergo.
Aiba began acting in a 1997 stage play based on an American coming of age film called Stand by Me with future bandmates Jun Matsumoto and Kazunari Ninomiya. In 2005, Aiba took up the lead role of Keiji Takashima (高島 啓治 Takashima Keiji), a naive but honest station attendant living in a world after a World War III nuclear war, in Tsubame no Iru Eki (燕のいる駅 A Station with Swallows).

After the announcement of the formation of Arashi in September 1999 and their position as supporters for the 1999 Volleyball World Cup competition, all five members starred together for the first time in the volleyball-centered short drama V no Arashi.
Although Aiba was featured in a number of dramas such as Mukodono 2003 (ムコ殿2003 The Son-in-Law 2003) and Yankee Bokō ni Kaeru (ヤンキー母校に帰る Drop-out Teacher Returns to School), he became more known for his appearances in variety shows instead and went on to focus on stage productions after Yankee Bokō ni Kaeru.
On August 2, 2009, it was announced that Aiba would not only act in his first drama series in nearly six years but also star as the lead actor for the first time. In My Girl, Aiba portrayed a young man who discovers that he has a five-year-old daughter after receiving the news that his girlfriend, who he has not seen in six years, was killed in an accident.
In January 2010, Aiba co-starred with the other members of Arashi in the human suspense drama special Saigo no Yakusoku. He portrayed Akira Tanada (棚田 昭 Tanada Akira), a 28-year-old coffee shop employee who is caught up in a building hijack.
