Japanese capex abroad

225 overseas projects by destination

By facility type

How these numbers are built: each project is one record, follow-up disclosures about the same project are folded into it, and foreign-currency amounts are left out of yen totals. Company totals match on the company's official English name. Annual-report facility plans enter with the filing date as their announcement date, so they are not used for month-by-month trends.
