Registrars accredited in Japan
10 registrars holding an ICANN accreditation in Japan (JP) report 3,933,080 legacy-gTLD domains under management.
This is where each registrar is accredited, not where domains or their owners are.
Neither zone files nor ICANN's monthly reports carry registrant location. A registrar accredited
here sells worldwide, and a domain registered through it may belong to anyone anywhere.
Methodology.
Registrar figures are for April 2026. ICANN publishes
monthly registry reports about three months in arrears, and they are the only
source that attributes domains to registrars — zone files do not contain
registrar information. Methodology.

Data currency. Domain counts on this page are from zone files dated and refresh daily. Registrar figures are from ICANN's monthly registry reports for April 2026, which ICANN publishes about three months in arrears; zone files contain no registrar information, so no fresher source exists.
