Following Arashi's hiatus, Aiba has continued to thrive as a solo entertainer, hosting the annual music special The Music Day, launching his own YouTube channel in 2024, and maintaining a strong presence in variety shows and dramas. As of 2026, he remains active in the entertainment industry, focusing on his individual projects.[edit]

Masaki Aiba was born on December 24, 1982, in Chiba Prefecture, Japan. He grew up in Chiba with his parents and an older sister. His father ran an Indian restaurant, and his mother was a homemaker. As a child, Aiba was energetic and loved sports, especially baseball and soccer. He attended Horikoshi High School in Tokyo, a school known for producing many entertainers, but did not graduate due to his busy schedule with Johnny & Associates.

In 1996, at age 13, Aiba passed the audition for Johnny & Associates and began his training. Before debuting with Arashi, he gained early acting experience by starring as the lead role of Gordie in the stage play Stand by Me in 1997, based on the film of the same name. This role marked his first significant step into the entertainment world.[edit]

Masaki Aiba debuted as a member of Arashi in 1999 with the single A·RA·SHI, launching one of the most successful careers in Japanese pop history. In 2004, he became a regular co-host of Tensai! Shimura Dōbutsuen, making him the first Arashi member to regularly host a non-Arashi variety show. This role solidified his reputation as a talented television personality.

In 2009, Aiba starred in his first leading drama role in My Girl, winning the Best Actor award at the 60th Television Drama Academy Awards. He followed this with the drama Lucky Seven in 2012, for which he won Best Supporting Actor at both the 73rd Television Drama Academy Awards and the 7th Tokyo Drama Awards. Throughout the 2010s, he became a central figure in Arashi's variety shows like VS Arashi and Himitsu no Arashi-chan!, and hosted his own radio show, Aiba Masaki no Arashi no Aibaka.

After Arashi's hiatus announcement in 2020, Aiba continued his solo work, starring in the drama series Kikazaru Koi ni wa Riyuu ga Atte (2021) and the film Gift of Fire (2023). He launched his personal YouTube channel, "Aiba Masaki's Channel," in 2024, which has over 500,000 subscribers.

In August 2026, the 93rd most famous person in Japan according to the iFANN Global Fame Rankings, his influence remains deeply rooted in daily life. Within the specific sphere of music, he holds the position of the 35th most famous person in J-Pop / J-Rock, a steady placement that reflects his enduring relevance since his debut. These metrics track global attention across media coverage, search, and consumption signals worldwide, yet they only scratch the surface of his actual connection with the public. His fanbase operates under the collective identity of "Arashi no Yousei," a unified group of over 345,000 Instagram followers who identify strictly through the agency's official system rather than individual monikers. There is no separate official name for Aiba alone; the community rallies as one. This cohesion was on full display during his 42nd birthday in December 2024, when fans coordinated massive digital and physical tributes. The bond is further proven by their ability to mobilize for charity drives and streaming campaigns, ensuring chart positions remain strong even during hiatuses. While individual nicknames like "Aibaka" exist as terms of endearment within the community, the group's collective power defines the experience. From reading bedtime stories during the pandemic to cheering at farewell tours, the audience treats Aiba as an emotional anchor, celebrating his genuine reactions and unscripted laughter as much as his professional achievements.[edit]

One widely retold story in Japanese pop culture centers on his reputation as the "sweetest idol," where his trademark smile became legendary for instantly calming crowds or lifting the mood of television audiences. Another iconic moment occurred in September 2021, when Aiba and Sho Sakurai announced their marriages simultaneously, causing Twitter to trend globally and marking a pivotal transition point for the group. During the COVID-19 pandemic in April 2020, he gained further affection by reading "The Three Little Pigs" to comfort families stuck at home. His role as host for major events after the death of Ken Shimura in March 2021 cemented his status as a resilient figure.
