Feel So Bad are a Japanese hard rock/heavy metal band that originally formed in 1993. Fronted by idol Daria Kawashima, the group initially had some very mild success, although Feel So Bad stopped breaking the Oricon charts by 1999. In 2001, Feel So Bad disbanded, but reunited temporarily in 2005, only to mysteriously disappear once more in 2008. In 2016, after a mysterious eight year long hiatus, the group suddenly resumed activities, and new material from Feel So Bad is reportedly currently in the works. In 2017, Feel So Bad released "Pentagon", which was their first original album in over a decade.
