To add English translations to a Japanese LRC file, insert a translated line directly after each Japanese lyric line using the identical timestamp, preserving the original LRC structure and timing for karaoke overlays.

You can translate Japanese lyrics into English while keeping LRC timestamps by overlaying the English text as a new line beneath the original Japanese line, ensuring both share the exact same synchronization tag.

The Japanese to English LRC translation process skips non-lyric metadata lines, already-English text, and Chinese characters, ensuring only Japanese lyric content is translated while structural integrity is preserved.

Repeated chorus lines are handled by enforcing consistent translations across all occurrences in the LRC file, ensuring that recurring Japanese phrases receive the same English translation each time they appear.

The best way to ensure natural-sounding English in Japanese lyric overlays is to apply semantic and rhythmic quality checks during translation, producing English lines that fit naturally within the LRC structure.
