Master Japanese PDF Annotation for Complex Pages

Mercor; Greater London; On-site; GBP 24,000 - 36,000; Full time

Job summary

Mercor seeks a meticulous Japanese language annotator to build structured maps of Japanese documents. You will identify page regions, label reading order, and faithfully transcribe kanji, kana, furigana, and handwritten content across diverse sources.

Applicants should be native Japanese speakers with experience in transcription/editing and a commitment to character-level accuracy. Remote, flexible hours, with rigorous review processes in place.

Qualifications

• You are a native Japanese speaker with full command of kanji, hiragana and katakana, including furigana and variant character forms.
• You have professional experience in interpretation, journalism, transcription, translation, editorial work, or comparable document-intensive work.
• You are exact: character-level accuracy matters more here than speed, and a single wrong character is a defect.
• You are systematic: you apply a taxonomy consistently across hundreds of pages rather than improvising per document.
• You are comfortable with unfamiliar layouts: vertical text, multi-column newspapers, exam papers, handwritten forms.

Responsibilities

• Source documents: find a publicly accessible Japanese PDF in an assigned document type, containing at least one multimodal element, and record where you obtained it.
• Annotate structure: identify and bound every meaningful region of the page - document title, section heading, paragraph, list, table, figure, diagram, caption, formula, question, answer field - and assign each a component type and a reading-order index.
• Record relationships: link each region to the figure or table it belongs to through a parent component identifier.
• Transcribe faithfully: reproduce all text exactly as it appears, including kanji, hiragana, katakana, furigana and handwritten content, flagging any region where the source is not legible.
• Capture page metadata: language, document type, source, page dimensions, and flags for tables, formulas and handwriting.
• Review a colleague's work: every task is reviewed end to end by a second Japanese expert, and experienced annotators take on that review.
