Lee Jun-ho (Korean: 이준호; born January 25, 1990), known mononymously as Junho, is a South Korean singer-songwriter and actor. He rose to prominence as a member of the South Korean boy band 2PM. Lee made his acting debut in the film Cold Eyes (2013) and has since appeared in films such as Twenty (2015), as well as notable television series such as Good Manager (2017), Rain or Shine (2017–2018), Confession (2019), King the Land (2023), Typhoon Family (2025), and Cashero (2025). His performance in The Red Sleeve (2021) earned him the Baeksang Arts Award for Best Actor. As a solo artist, Lee has released two studio albums, one compilation album and eight extended plays, achieving significant success in Japan.
Lee was inspired to pursue filmmaking after watching the film Shiri in elementary school. However, by the fourth grade, his interests had shifted toward acting. Although he initially enjoyed dancing and singing, he aspired to become an actor and subsequently enrolled in the drama program at Sewon High School. While in high school, Lee was active in the school's theater club and participated in various provincial and poetry competitions.
Lee attended Howon University in Gunsan, South Korea, where he completed his undergraduate studies. He later earned a master's degree in cinematography from Sejong University.
In 2006, Lee first gained public attention when he won Superstar Survival. The show began with twelve teenage competitors, who were eliminated one by one over the course of the competition until three finalists remained. Its format was similar to that of the reality show Survivor. Lee signed a contract with JYP Entertainment after winning the contest, placing first among 6,500 competitors.
In 2008, he participated in Mnet's Hot Blooded Men, a program that followed the rigorous training of thirteen aspiring trainees competing for a coveted place in the boy band One Day. The program ultimately led to the formation of two boy bands, 2AM and 2PM.
Half a year after the airing of Hot Blooded Men, 2PM made their debut with the single "10 Out of 10" from their first single album, Hottest Time of the Day. The group gained mainstream success in South Korea following the release of their second single album, 2:00PM Time For Change, in 2009.
Despite the group's success, Lee has spoken about his lack of opportunities and recognition early in his career. He recalled that he was often alone in the dormitory while the other members were busy with their scheduled activities. Lee also stated that, despite his interest in acting, he believed JYP Entertainment had no intention of allowing him to pursue it at the time.
In 2013, Lee made his debut as a solo artist in Japan with the release of his debut solo EP, Kimi no Koe, for which he served as producer, composer, and lyricist across all tracks. The EP topped Tower Records' daily chart and peaked at number three on Oricon's daily and weekly album charts. On July 9, Lee began his first solo tour, Kimi no Koe, which comprised 12 shows across five cities and concluded on August 29 in Tokyo.
On July 9, 2014, Lee released his second self-composed Japanese EP, Feel. The EP topped Oricon's daily album chart on the day of its release and reached number two on the weekly chart. On July 3, Lee began his second solo Japanese tour, Feel, which encompassed 12 shows across five cities and attracted 50,000 fans. The final show at the Nippon Budokan on August 13 was broadcast live in 38 theaters across 23 prefectures in Japan.
On July 15, 2015, Lee released his third Japanese EP, So Good, which peaked at number three on Oricon's weekly albums chart, with first-week sales exceeding 40,000 copies. The EP was described as demonstrating Lee's growth as an artist, with emotional tracks like "Good Life" and "Pressure" reflecting his personal thoughts and emotions. On July 7, Lee began his 2015 Japanese tour, Last Night, which comprised 15 shows across seven cities and attracted over 55,000 fans. The tour included two performances each at Yokohama Arena and World Memorial Hall. The final show at the World Memorial Hall on August 6 was broadcast live in 41 theaters across 32 cities in Japan.
In September, Lee released his debut studio album in South Korea, One, consisting of Korean versions of eleven previously released self-composed Japanese tracks. For the album's promotion, Lee made his first solo appearances on South Korean music shows, including M Countdown, Music Bank, Show! Music Core and Inkigayo, performing the title track "Fire". He subsequently held two Last Night concerts at the Olympic Hall in Seoul on September 19 and 20.
In July 2016, Lee released his fourth Japanese EP, DSMN. The EP became Lee's first release to top both Oricon and Tower Records' daily albums charts, and peaked at number two on Oricon's weekly albums chart. The pre-release single "DSMN" also gained popularity on a Japanese ringtone platform. Lee held a special fan event, Whispering Summer with Junho ~Acoustic Talk Night~, on August 22. His fourth Japanese tour, Hyper, concluded with two performances at the Yoyogi National Gymnasium on August 24 and 25. Lee was responsible for the concert's overall production, including the setlist, opening video, costume concept, stage sound and lighting. On December 3 and 4, Lee held the special encore concerts Last Hyper Night at the Nippon Budokan, with 20,000 fans in attendance. The concerts were also broadcast live at theaters across Japan.
In July 2017, Lee released his fifth Japanese EP, 2017 S/S, which peaked at number two on Oricon's weekly albums chart. Tower Records ranked it as the second best-selling Japanese release of 2017 by a Korean artist. From July to August, Lee held his fifth Japanese tour, 2017 S/S.
In September 2017, Lee released his first Korean EP, Canvas. Music videos were released for "Fine", which Lee dedicated to his late cat Rambo, "Bye Bye" featuring Cheeze, and the title track "Canvas". Following the EP's release, Lee held a fan event, The Special Day "Canvas", on September 16.
In January 2018, Lee released his sixth Japanese EP, Winter Sleep, departing from the summer release and touring pattern established by his previous five Japanese EPs and accompanying tours, which had earned him the moniker "Lee Natsu" ("Lee Summer"). The title track "Winter Sleep" was released in both Korean and Japanese. The EP topped Oricon's daily albums chart and Tower Records' weekly albums chart, and peaked at number three on Oricon's weekly albums chart. Lee also held his first solo winter tour in Japan, Winter Boy (冬の少年), which comprised nine shows across five cities and concluded with two performances at the Nippon Budokan on February 23 and 24.
