List of highest-grossing films in Japan

The following is a list of the highest-grossing films in Japan. This list only accounts for the films' box office earnings at cinemas and not their ancillary revenues (i.e. home video sales, video rentals, television broadcasts, or merchandise sales). Two tables are listed in terms of nominal gross revenue, while the two other tables are listed in terms of box office admissions.

Box office revenue
Among the films that have grossed over ¥10 billion in Japan, nineteen are Japanese films.

Box office admissions
The following table lists high-grossing films by the number of box office admissions, which refers to the number of cinema tickets sold at the Japanese box office. Only films that have sold at least 10 million tickets are listed. The list is not ranked, as the list is incomplete.

A separate column lists the gross revenue adjusted for ticket price inflation in 2021, based on data from the (MPPAJ). The adjusted gross revenue is calculated by multiplying the total number of admissions by the average 2021 ticket price (¥1,410). Admissions better reflect the popularity of older films, since they are less susceptible to the effects of inflation. This mainly affects films released prior the 1990s, as there has been very little Japanese ticket price inflation since the 1990s. Where the number of admissions is unknown, they are estimated by dividing the nominal gross revenue by the average ticket price in the year of release (or the distributor rentals by the average rental earnings per ticket) to provide an estimate.
