Super Junior members Donghae and Eunhyuk performed together at the "a-nation" concert that was held at the Tokyo Agimoto Stadium on August 31.

The two idol stars performed for fans under the event "Donghae & Eunhyuk, A Promise To Reunite With Fans," according to the Japanese publication Sankai Sports.

Donhae and Eunhyuk debuted as a separate unit from Super Junior and started promoting themselves as a duo in Japan back in 2012, building a solid fan base for themselves since.

During the "a-nation" concert, the boys were seen performing tracks from their third single album, including "Skeleton" and "Oppa, Oppa" for the 55,000 local fans that attended the event, according to the Korean publication Naver.

"Last year, we performed at 'a-nation' as Super Junior, but we're very happy to be performing as our own unit of Donghae and Eunhyuk this time," explained Donghae at the concert.

Eunhyuk added, "Please show a lot of love for Super Junior's new album. All the members of Super Junior will be coming to visit you guys soon so please wait for us just a little bit longer."

Super Junior released their seventh studio album "Mamacita" on August 29 after two years of hiatus, according to the publication Asia One. The music video for their title track has already become so popular it was seen ranking No. 1 on China's YinYueTai Music Video Chart, according to Allkpop.

"The term 'mamacita' has many different meanings actually ... but in English it can be thought of like, 'She is gorgeous," stated member Lee Teuk during a press conference with his fellow bandmates at the Imperial Palace Hotel in Seoul last week.

Lee added, "The basic concept of this album is having our musical components and especially, this time around we feel as though we have come back as handsome, real men. I think for the past 10 years we have always been trying to tackle the concept of being manly."
