🤗 Also on Hugging Face: the same files as a versioned dataset with a card and per-source licences — loreatec/japan-procurement-open-data (load it straight into pandas with hf://datasets/loreatec/japan-procurement-open-data/awards_fy2025.csv.gz). This site stays the authoritative, always-current copy.
Not included on purpose: the full 5.8M-company registry (get it from the NTA), prefectural construction-licence rosters (per-prefecture terms), and anything personal. Want these datasets on Hugging Face or a bigger quota? contact LoreaTec.
