Job summary

Mercor seeks native Japanese annotators to build high-quality transcription and structural maps of Japanese documents. You will faithfully reproduce kanji, kana, furigana and handwritten content while marking regions and their reading order.

This role emphasizes accuracy over speed, with peer review by a second expert. You will work on diverse real documents, including handwriting and multi-column layouts, to diversify the corpus for AI training.

Qualifications

• Native Japanese speaker with full command of kanji, hiragana and katakana, including furigana and variant character forms.

• Annotate structure: identify and bound every meaningful region of the page and assign a type and 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, kana, furigana and handwritten content.
• 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.
