The Korean historical drama "Harbin" surpassed the 1 million admissions mark Wednesday, just one day after its release, the film's distributor said.

As of Wednesday afternoon, the film's cumulative admissions reached over 1 million, after garnering more than 380,000 on its release day, according to CJ ENM and data from the Korean Film Council.

"Harbin" debuted at No. 1 at the local box office Tuesday, dethroning the disaster film "Firefighters," which had topped the weekend box office for the second consecutive week.

Set in 1909, the espionage thriller depicts a tense mission to Harbin in northern China, featuring Korean independence fighter Ahn Jung-geun (1879-1910), who assassinated Ito Hirobumi, Japan's first prime minister and resident-general of Korea, at Harbin Station.

Korea was under brutal Japanese colonial rule from 1910 to 1945.
