At the beginning of 2015, BTS toured Japan for the first time with their Wake Up: Open Your Eyes tour. They also held their second solo concert in Korea, BTS Live Trilogy - Episode 1: BTS Begins. Their third EP, The Most Beautiful Moment in Life, Part 1 (2015), was released that March and was the only Korean album to be included in Fuse's list of the "27 Best Albums of 2015 So Far" that year. The lead single "I Need U" was a top five hit on the weekly Gaon Digital Chart in South Korea and garnered BTS their first ever music show win on SBS MTV's The Show.

Although the second single, "Dope (Korean: 쩔어; RR: Jjeoreo)", peaked at number 44 on the weekly Gaon Digital Chart, its music video became BTS' first to accrue over 100 million views on YouTube in October. "Dope" later peaked at number three on Billboard's World Digital Songs Chart. The Most Beautiful Moment in Life, Part 1 have sold over 300,000 copies to date.

BTS' fourth Japanese single, "For You", was released that June to celebrate the first anniversary of their Japanese debut. The single topped Oricon's daily chart, selling over 42,000 copies within its first day. They also commenced their 2015 Live Trilogy Episode: The Red Bullet world tour, and participated in the Summer Sonic Festival tour in Japan.

During their three-day The Most Beautiful Moment in Life: On Stage tour, the group performed the new song "Run", the lead single for the EP The Most Beautiful Moment in Life, Part 2 later released on November 30, 2015. The album topped the weekly Gaon Album and Billboard World Albums charts and remained atop the latter for multiple weeks, making BTS the first K-pop act to achieve that feat. It also peaked at number 171 on the Billboard 200 Chart with over 5,000 copies. At the 2015 Mnet Asian Music Awards, they received the Best World Performer in recognition of their international fanbase.

The Most Beautiful Moment in Life, Part 1 and Part 2 were later combined into the Young Forever (2016) edition, and was supported by three singles: the top 40 hit "Epilogue: Young Forever", the top 10 hit "Fire" (Korean: 불타오르네; RR: Bultaoreune), and the top 20 hit "Save Me". A two-day concert at the Olympic Gymnastics Arena in Seoul was held in May to support the album, followed by their Asia tour. The group also headlined both US KCON shows held that year in New Jersey (June) and Los Angeles (July), to sold out audiences. Young Forever later won Album of the Year at the year-end Melon Music Awards, becoming the group's first major grand prize (daesang).

On September 7, 2016, BTS released their second Japanese studio album Youth, selling over 44,000 copies on its first day of release and ranking number one in Japan. Japanese editions of "I Need U" and "Run" were released as singles. Meanwhile, back in their home country, pre-orders for the group's second Korean studio album, Wings, released that October, accumulated over 500,000 copies within the first week. The lead single "Blood Sweat & Tears" achieved an "all-kill" in South Korea, becoming their first number one hit on the weekly Gaon Digital Chart.

Its music video gained over 6 million views within 24 hours, breaking the previous record held on YouTube for the highest number of views of a K-pop group music video within 24 hours. They later won Artist of the Year at the 2016 Mnet Asian Music Awards, becoming the first artist not from a "Big Three" entertainment company (SM, YG and JYP) to do so.
