Satoshi Ohno (大野 智, Ōno Satoshi; born November 26, 1980) is a former Japanese idol, singer, actor, radio host, artist, dancer, and choreographer, registered under Johnny & Associates and later under Starto Entertainment. He was the lead vocalist and leader of the boy band Arashi, hence his nickname Leader (リーダー, Rīdā).
Ohno began his career in the entertainment industry when he joined the Japanese talent agency Johnny & Associates in 1994 at the age of 13. He started an acting career in 1997 when he was cast to be part of the stage play Kyo to Kyo. In 2008, Ohno became the first and the only artist from Johnny's to hold his own art exhibition, titled "Freestyle", and also received his first starring role in a Japanese television drama, Maō, for which he earned a handful of Best Actor awards. Since then, he continued to star in numerous dramas and movies, receiving a number of awards and nominations for his roles. For his work as an artist, a singer, and an actor in Kaibutsu-kun the Movie, Ohno became one of the recipients of GQ Japan's Men of the Year Award in 2011.
In February 2026, it was announced that, together with the end of activities of the group, Ohno would be leaving the agency on May 31, 2026.
In July 2026, Ohno appeared on a video reporting the opening of his official website and SNS.
Ohno was born in Mitaka, Tokyo as the youngest child of his family. He has one older sister. During middle school, his mother sent in his application to Johnny & Associates without his knowledge. An invitation to audition was sent back to Ohno, and he subsequently became a trainee in October 1994. To focus on the stage play Kyo to Kyo, which ran from 1997 to 1998 during his trainee days, he withdrew from high school and moved to Kyoto.
Following Arashi's hiatus, Ohno had been absent from the public eye, except for a minimum of messages transmitted via the other members. In late April 2024, he provided an interview to a Post Seven reporter, in which he talked about meeting with the others at late night to talk, given the other's busy schedules. Among the things he talked about was Arashi's newly opened company and Ninomiya's independence from Smile-Up. He barely spoke about the hiatus and totally evaded the question of his commercial businesses opening around Miyakojima, Okinawa, including a hotel and a bar. Ohno has been investing in real estate since 2017, with plans to build a tourist resort. Of these, he said "I don't want to talk about it because it's private". He also talked about learning to drive. He said that it wasn't because of his needing to drive to Miyakojima, but because he felt it was time he learned, since, before, he had to rely on others to take him wherever he needed to go. About the return of activities as Arashi, Ohno said that nothing has been decided yet, not even a return concert that was rumored to be held in Spring next year.
On February 28, 2026, in a post by Starto Entertainment, it was announced that Ohno would leave the agency the same day of Arashi's end of activities, May 31, 2026. In a letter, also shared by Starto, Ohno thanks everyone involved during all the years of his career, including the members (of Arashi) and the fans, who have been supporting him since the beginning. He did not mention retiring from entertainment, but he did point out that after the last concert, he would like to do what he can at his own pace, being true to himself.
Before his music debut with Arashi, Ohno wanted to resign from Johnny & Associates. However, then-president Johnny Kitagawa asked him to help out with a song recording and to pack up for a trip to Hawaii, which turned out to be the place where the press conference announcing the formation of Arashi was held. With Ohno at the age of 18 at the time, Arashi was officially formed on September 15, 1999, and made their CD debut on November 3, 1999. Since much of his trainee days were spent in Kyoto, he was the least known member during Arashi's early days.
Ohno was the lead vocalist of Arashi. Although his music career is primarily with Arashi, he had a solo concert called 3104 (which can be read as his name Satoshi in Japanese) in 2006 and in 2009, became the first and only member in Arashi to release a solo single. It was a soundtrack for his drama Uta no Onii-san titled "Kumorinochi, Kaisei" (曇りのち、快晴) by Yano Kenta starring Satoshi Ohno. Ohno also provided the vocals to the insert song "Yukai Tsukai Kaibutsu-kun" (ユカイツーカイ怪物くん), which was released as a single on July 7, 2010, for the drama Kaibutsu-kun and sold around 59,000 copies on the first day.
Ohno's work as a choreographer began in 2004 for his solo "Top Secret" during Arashi's 2004 Iza, Now Tour, and in 2006 for the group. Since then, he has done numerous solo and group dances, some of his notable group choreography including "Zero-G", the live performance for "Bittersweet", the interlude for the "Kokoro no Sora" music video, "Tsunagu", and "Do You...?".
In 1997, Ohno was a cast member of Kyo to Kyo with Musical Academy (MA) leader Shingo Machida and continued to act in other stage productions such as Koichi Dōmoto's Mask and Shōnentai's Playzone after Kyo to Kyo was over. Since then, he has done a number of stage plays such as True West with Masahiro Matsuoka and West Side Story with bandmates Sho Sakurai and Jun Matsumoto.
The Pū (プーシリーズ, Wind) series that Ohno starred in spanned from 2003 to 2008, consisting of Sengokupū (センゴクプー), Bakumatsu Banpū (バクマツバンプー), Tensei Kunpū (テンセイクンプー), and Amatsukaze (アマツカゼ). In Tensei Kunpū, Ohno portrayed a man named Kaoru Kazamine who was accidentally sent back to the Edo period of Japan through a system malfunction.
In 1999, Ohno made his TV drama debut in the volleyball-centered short drama V no Arashi (Vの嵐), which was Arashi's first drama together.
In 2008, Ohno was given his first starring role in the suspense drama Maō. He co-starred with Toma Ikuta and portrayed a two-faced lawyer who sought for revenge against the person who murdered his brother years ago.
In 2009, he starred in his first comedy drama Uta no Oniisan (歌のおにいさん, Brother of Songs). With Kanjani Eight member Ryuhei Maruyama as his co-star, Ohno played a musician who unexpectedly becomes a singing character for a children's program after being dumped by his girlfriend, kicked out of his band, and labelled useless by his family. Ohno also took part in a television mini-drama project titled 0 Gōshitsu no Kyaku (0号室の客, Guest in Room 0), which aired from October 2009 to April 2010 and starred a select number of different artists from Johnny's. Ohno was the lead actor in the first story of the project called "Akogare no Otoko" (憧れの男, Yearning Man), which ran for four episodes in total. The story was about a salaryman and a club hostess visiting a strange "Room 0" that can reveal anyone's "grade" as a human being.
In January 2010, Ohno co-starred with the other members of Arashi in the human suspense drama special Saigo no Yakusoku (最後の約束, Last Promise). Ohno portrayed Satoru Mashiko, a 28-year-old employee of a cleaning company who is caught up in a building hijack. Beginning in April 2010, Ohno starred in the live-action adaptation of the manga and anime Kaibutsu-kun. Ohno played Tarou Kaibutsu, the prince of Kaibutsu Land who is ordered by the king to go to the world of humans for training as he is deemed unfit for the succession of the throne. He then reprised his role of Kaibutsu-kun for the Kaibutsu-kun special which aired on June 26, 2010. Ohno also starred in the second story, Hajime no Ippo (はじめの一歩, First Step), of the Fall 2010 Yonimo Kimyōna Monogatari (世にも奇妙な物語) special that aired on October 4, 2010.
In October 2011, Ohno once again reprised his role of Kaibutsu-kun for another Kaibutsu-kun special, leading up to the story of the 3D movie version.
On January 3, 2012, Ohno starred in the drama special Mou Yuukai Nante Shinai (もう誘拐なんてしない, I Won't Kidnap Anymore). He played the role of Shotaro Tarui, a freeter who can't forget his childhood dream of being a hero. However, he finds himself planning a fake kidnapping after he receives a request from the daughter of a boss of racketeers, played by co-star Yui Aragaki. Beginning in April 2012, Ohno co-starred with Erika Toda in his first Getsuku drama, Kagi no Kakatta Heya (鍵のかかった部屋, Locked Room). He played the lead character, Kei Enomoto, an employee at a major security firm who has an obsession with keys and locks. Enomoto works with a pair of attorneys, solving mysteries that fall under the "locked room" genre, in which seemingly impossible crimes are committed.
