Field notes
The page says its monthly Japan records are normalized from official customs statistics, with origin-country entries and source references alongside independently reconciled national totals. It defines supplier by customs country of origin, and keeps each country’s import values in its source currency: JPY for Japan and USD for South Korea. The extract describes matching-period comparisons and hypothetical supplier reductions, though it does not expose their interface.
