Kouro Launch — Search 130M Japan Customs Records in the Browser

We've launched Kouro, a SaaS for analyzing Japan customs trade statistics in the browser.

Data scope

Type	Volume
Import/export detail rows	~130M (1988–present)
HS codes	1,050+ (2-digit chapters to 9-digit statistical lines)
Countries & regions	200+
Customs offices	146
Update cadence	Monthly (preliminary → final → import final, 3 stages)

The single source of truth is the Japanese MOF customs portal. Kouro syncs the previous business day's release every morning at 10:00 JST.

Sample queries

• "HS 8703 (passenger cars) exports to the US, monthly, last 3 years"
• "HS 271012190 (naphtha) import sources and unit price"
• "Vehicle exports through Nagoya customs, stacked by destination country"

What used to take 30+ minutes in MOF's PDFs or e-Stat is now reproducible from a single URL on Kouro, with CSV / Excel / PDF export.
