Nico Touches the Walls was a Japanese rock band formed in 2004. The band members were: Mitsumura Tatsuya, Sakakura Shingo, Furumura Daisuke & Tsushima Shotaro. In the same year, they won the Lotte Prize at the Yamaha Teen Music Festival. Rising quickly, they signed to "Senha & Co." before signing to Sony Music Japan's Ki/oon Records in 2007. Their debut single, in a major label, "Yoru no Hate", was released in February 2008.

Vamps is a Japanese rock duo formed in 2008 by Hyde and K.A.Z. Only a year after their founding, Vamps performed its first international tour, ten dates in the United States, and in 2010 they went on their first world tour. Originally signed to Hyde's own record label Vamprose, every release the band has had to date has reached the top ten on the Oricon music chart. In 2013, the group changed labels to Universal Music Group's Delicious Deli Records and produced their worldwide debut release. After several tours and collaborations with Western acts, Vamps worked with outside producers and songwriters for the first time on the 2017 album Underworld before temporarily ceasing all activities at the end of that year.
