Drop in your Korean .srt or .vtt file. SubLingo parses every cue and locks the timings in place.
Set the target language to Japanese. The source is auto-detected, so you can leave it on Korean or let it detect.
Run the translation. Only the text inside each cue is rewritten in Japanese — never the timecodes.

Translating from Korean into Japanese: Japanese subtitles run without spaces between words, so line breaks fall at natural phrase boundaries; players usually cap each line around 13–16 full-width characters per line. Because only the text inside each cue changes, every timecode from the original Korean file carries over unchanged.

Most Korean subtitle files translate to Japanese in a few seconds. Longer files with thousands of cues take a little more, but you stay on the page the whole time.
Typical movie and episode subtitle files — a few hundred KB and a few thousand cues — translate without trouble. Very large files may take longer to process, but the timecodes still come back unchanged.
