Back in January, Red Velvet dropped a bouncy Japanese single - accompanied by an aptly playful visuals - called "Sappy." A little over three months after, the K-pop quintet released concept photos revealing a colorful theme for their upcoming sophomore Japanese EP of the same name.

Though sporting rather serious sultry gazes in one of the two photos, all members - namely Joy, Wendy, Irene, Seulgi, and Yeri - are wearing ensembles with a touch of bold, bright hues like red, orange, green, and blue.

In the other photo, the ladies exude another brand of femininity with their pastel-themed numbers. The photo-teaser features them and their group name (yes, in bright red font) creatively nestled in a leafy background image. 

According to previous reports, "Sappy," the mini album," will be released on May 29. It will also include Japanese versions of their hit tracks "Peek-a-Boo," "Power Up," and "Rookie."

It was in July 2018 when the group launched their first-ever Japanese EP, "#Cookie Jar." The well-received offering peaked at No. 3 on the Oricon Weekly Album Chart and No. 4 on Billboard Japan's Hot Albums Chart.

The said record includes the titular single, plus two more original tracks "Aitai-tai" and "Cause It's You." Completing the six-track effort are the Japanese recordings of their songs "Dumb Dumb," "Russian Roulette," and "Red Flavor."

Red Velvet first debuted in August 2014. Then a four-piece act (sans Yeri), they made a strong debut securing "Rookie of the Year" trophies from the Golden Disk Awards and Seoul Music Awards. 

In 2015, Yeri joined the group; since then the R&B-synth pop quintet has become one of the most globally recognized K-pop acts of their generation - with smashes like "Bad Boy," "Ice Cream Cake and the aforementioned under their belt. 

Back in February - a month after they released "Sappy," the single - Red Velvet embarked on a North American and Canadian tour, the first for a K-pop girl group in three years. They performed for their fans across Los Angeles, Miami, Dallas, Chicago, Newark, Toronto, and Vancouver.

Earlier in April, the group was also featured in the remix of Ellie Goulding and Diplo's "Close To Me," which featured Korean lyrics they contributed themselves.
