Japanese popular culture not only reflects the attitudes and concerns of the present but also provides a link to the past. Japanese cinema, cuisine, television programs, manga, and music all developed from older artistic and literary traditions, and many of their themes and styles of presentation can be traced to traditional art forms. Contemporary forms of popular culture, much like the traditional forms, provide not only entertainment but also an escape for the contemporary Japanese from the problems of an industrial world. When asked how they spent their leisure time, 80 percent of a sample of men and women surveyed by the government in 1986 said they averaged about two and one-half hours per weekday watching television, listening to the radio, and reading Japanese newspapers or magazines. Some 16 percent spent an average of two and one-quarter hours a day engaged in hobbies or amusements. Others spent leisure time participating in sports, socializing, and personal study. Teenagers and retired people reported spending more time on all of these activities than did other groups.

Popular culture (commonly known as pop culture) is the totality of ideas, perspectives, attitudes, memes,images and other phenomena that are preferred^{[citation needed]} by an informal consensus within the mainstream of a given culture, especially Western culture of the early to mid 20th century and the emerging global mainstream of the late 20th and early 21st century. Heavily influenced by mass media, this collection of ideas permeates the everyday lives of the society.

Popular culture is often viewed as being trivial and dumbed-down in order to find consensual acceptance throughout the mainstream. As a result, it comes under heavy criticism from various non-mainstream sources (most notably religious groups and countercultural groups) which deem it superficial, consumerist, sensationalist, and corrupted.

The term "popular culture" was coined in the 19th century or earlier to refer to the education and general "culturedness" of the lower classes, as was delivered in an address at the Birmingham Town Hall, England. The term began to assume the meaning of a culture of the lower classes separate from (and sometimes opposed to) "true education" towards the end of the century, a usage that became established by the interbellum period. The current meaning of the term, culture for mass consumption, especially originating in the United States, is established by the end of World War II. The abbreviated form "pop culture" dates to the 1960s.

J-pop, an abbreviation for Japanese pop, is a musical genre that entered the musical mainstream of Japan in the 1990s. Modern J-pop has its roots in 1960s pop and rock music, such as The Beatles, which led to Japanese rock bands such as Happy End fusing rock with Japanese music. J-pop was further defined by New Wave bands such as Yellow Magic Orchestra and Southern All Stars in the late 1970s. Eventually, J-pop replaced kayōkyoku ("Lyric Singing Music", a term for Japanese pop music from the 1920s to the 1980s) in the Japanese music scene. The term was coined by the Japanese media to distinguish Japanese music from foreign music, and now refers to most Japanese popular music.

The origin of modern J-pop is said to be Japanese-language rock music inspired by The Beatles. Unlike the Japanese music genre called kayōkyoku, J-pop uses a special kind of pronunciation, which is similar to that of English. One notable singer to do so is Keisuke Kuwata, who pronounced the Japanese word karada ("body") as kyerada. Additionally, unlike Western music, the major second (sol and la) was usually not used in Japanese music, except art music, before rock music became popular in Japan. When the Group Sounds genre, which was inspired by Western rock, became popular, Japanese pop music adopted the major second, which was used in the final sounds of The Beatles' song "I Want to Hold Your Hand" and The Rolling Stones' song "(I Can't Get No) Satisfaction". Although Japanese pop music changed from music based on Japanese pentatonic scale and distortional tetrachord to the more occidental music over time, music that drew from the traditional Japanese singing style remained popular (such as that of Ringo Shiina).
