Frequently asked questions
About the data
How often is the database updated?
The collection pipeline runs four times a day (Japan time), catching same-day disclosures including the after-market-close rush. New entries are published after passing QA — typically the same day or the next morning.
Where does the data come from?
Primary sources only: TDnet timely disclosures, EDINET securities filings, corporate press releases (PR TIMES and 27+ company newsrooms monitored directly), METI subsidy award lists, and prefectural investment-agreement announcements. Every entry links back to the original document.
Do you translate news from other media?
No. Every entry is built directly from the primary disclosure, not translated from other outlets. Facts are verified against the original document before publication.
How accurate are the investment amounts?
Amounts are extracted from the original filing and machine-checked against the source text (including an order-of-magnitude cross-check), then human-reviewed before publication. When a filing doesn't disclose an amount, the field stays empty — we never estimate.
What does 'construction phase' mean?
Each project is tagged planned (announced, not yet started), construction (ground broken), or completed (operational). The phase reflects the status at the time of the source document.
A project is missing or has an error. Can I report it?
Yes, please — email hello@jscope.tech. Corrections are verified against primary sources and fixed quickly. Coverage suggestions for new sources are equally welcome.
