Dr. Downer's aggressive punk rock sound is rooted in the notes and beats of Japanese traditional folk music. The band name Dr. Downer is taken from the U.K. band Dr. Feelgood and Nirvana's song Downer.
The band is based in Yokosuka city, a residential suburb of the Tokyo-Yokohama urban area. They sometimes release their songs in the format of cassette tape.
Since 2010, their songs are released under the label Only in Dreams launched by Masafumi Gotoh.
