This study analyzes information compression and reconstruction in Japanese subtitles of Korean dramas distributed on Netflix. Focusing on the long-established Japanese subtitle convention known as the “four-characters-per-second” norm, the study examines how information is compressed and reconstructed under the constraints of Japanese subtitle translation. The average number of characters and characters per second (CPS) were calculated based on a corpus of six Korean dramas comprising nine episodes and 7,569 subtitle segments, and quantitative shifts in lexical retention were analyzed across different parts of speech. Translation examples were also examined to identify strategies of information reduction and reorganization. The results show that, despite differences in dialogue density and genre, most subtitles maintained a reading speed close to four characters per second. Nouns and verbs exhibited relatively high retention rates, whereas adverbs and interjections were frequently omitted. The findings indicate that Japanese subtitles selectively preserve core information while reducing peripheral elements through various forms of linguistic reconstruction, thereby facilitating the efficient transmission of core meaning under temporal and spatial constraints.
