A greenfield investment announcement is a useful signal, but it is not the end of the evidence chain. Projects can change size, timing, location, ownership, or operating scope. A publication that treats every announcement as completed investment will overstate activity and make later comparisons unreliable.
Use stages, not one status
Build a project record with separate stages: announced, permitted, financed, construction started, asset completed, and operations started. Not every project uses every stage, and public evidence can be incomplete. The purpose is not to force certainty. The purpose is to show exactly what has been confirmed.
The JETRO Invest Japan Report 2025 discusses recent inward investment and greenfield activity in Japan. Use the report for the aggregate context that it provides. For an individual project, keep the project announcement and any later operating evidence in separate fields. Do not use an aggregate trend to fill a missing project status.
Record the following items for each project:
- investor and ultimate parent at the report date;
- announced location and facility type;
- stated capital amount and whether it is an estimate;
- expected schedule;
- source date and source organization;
- current verified stage; and
- the last date on which the stage was checked.
If an amount covers several countries or phases, do not assign all of it to one location. If a company gives a capacity target without capital spending, do not estimate the investment unless the method is stated and clearly labeled as analysis.
Keep planned and realized measures apart
An announcement count can show corporate interest. Construction starts can show that more projects moved beyond intention. Operational facilities can support a claim about realized capacity. These are three different measures. A strong dashboard can show all three, provided the labels and dates remain visible.
Cross-border comparisons also need a common rule for cancellations and delays. Do not delete an announced project after it is cancelled. Change its status and preserve the earlier evidence. This prevents the history from becoming artificially clean and lets a reader measure the distance between announced and realized activity.
End with a verification note
Every project profile should state what is not yet known. Examples are an undisclosed investment value, a schedule that has not been updated, or a facility that has not announced operations. An explicit evidence gap is safer than a confident guess.
The result is a project ledger that can support later analysis. It can show where capital signals are concentrated, how quickly projects advance, and which sectors have the widest gap between announcements and operation. Those conclusions become stronger because the underlying stages were not compressed into one word.
