IV△7–V7–iii7–vi progression
The IV△7–V7–iii7–vi progression, also known as the Ōdō shinkō (王道進行) or Koakuma chord progression (小悪魔コード進行, koakuma kōdo shinkō),[1] is a common chord progression within contemporary Japanese pop music. It involves the seventh chords of IV, V, and iii, along with a vi chord; for example, in the key of C major, this would be: F major 7–G7–E minor 7–A minor.[2][3]

Nomenclature
The informal name for the progression, Ōdō shinkō (王道進行), literally translates to "royal road progression"; the expression ōdō (王道, "royal road") is used in Japanese to describe an easy or painless method to do something.
An alternative term, Koakuma chord progression, was originally coined by Japanese music producer Seiji Kameda on the 2014 NHK television show Kameda's Music Academy (亀田音楽専門学校, Kameda ongaku senmon gakkō). The phrase koakuma (小悪魔, lit. "little devil") is a pejorative used to describe a seductive lover who teases with one's feelings;[4] as the chord progression involves two major chords in succession followed immediately by two minor chords, Kameda describes the moment where the progression moves from the major dominant chord to the minor mediant chord as akin to the moment of heartbreak induced by a playful lover, hence the name.[5]
History
The IV△7–V7–iii7–vi progression was originally influenced by jazz and rock progressions originating in Western music. Music featuring similar chord progressions were introduced to Japan via Eurodisco-influenced pop tracks that became popular during their early boom in Japan. The chord progression has become prolific in J-pop to the point where it has become a core part of modern Japanese music;[3] pop music lacking the progression is often described as sounding "not Japanese". While artists' overuse of the ōdō progression can often be criticised as lacking in creative originality, the corpus of songs that become bestsellers in Japan and perform well on Japanese record charts feature plenty of tracks utilising the progression,[3] thus contributing to the conservative nature of record labels that lean towards familiar progressions over more risky experimentation.
