Boy group Nu'est gave fans in Japan the full K-pop star experience this summer.

The five-member idol group wrapped up their "Nu'est Japan Tour 2014 One L.O. Λ.E" concerts on August 25, according to the Korean publication Osen Entertainment.

The recent tour was launched to celebrate the success of their album "Nu'est Best In Korea," which was released on July 30, according to Yahoo Entertainment Singapore. The boys performed for fans in Nagoya, Osaka and Tokyo on August 18, 21 and 25, singing for a total of approximately 5,000 audience members.

Nu'est is all about changing their concept and image with every comeback.

"Nu'est tries to show different themes with every new album," explained member JR during an interview in 2013.

It's clear that their recent choice of theme was quite a success. "Nu'est Best In Korea" debuted at No. 1 on Japan Tower Records Daily Charts for three consecutive days.

A giant poster of Nu'est is hanging on every floor of Tower Records Shibuya branch.

Nu'est grasped the hearts of local fans with the first performances of their hit tracks "Good Bye Bye," "Story Book," "A Love Without Love" and more.

During the last concert in Tokyo, the members revealed that Nu'est would be making their Japanese debut on November 5 with the release of their single "Shalala Ring."

Nu'est's musical domination doesn't stop at Japan. The K-pop group will head to Chile, Peru and Brazil to launch their new tour.

Since their debut, the five idol members of Nu'est have grown closer than ever as they reach to the top of the K-pop world.

"Aron is 2 years older than the rest of us, and because the rest of are all the same age, we have a great friendship. Since we're all living in the same house, we all take different roles, as well. Aron is like the father, and I'm like the mom. (Laughter) We try to understand each other, and that makes us feel like we're a real family. We spend our leisure time together watching movies or playing games," stated member Minhyun.
