Who called me from +81 (Japan)?
Incoming calls with the international prefix +81 originate from telephone networks registered in Japan. Standard telephone numbers in this country adhere to the national numbering format: Domestic 0 + area code (1-4 digits) + subscriber number; mobile 070/080/090. You can enter the full number into our lookup box above to inspect community reports, telemarketing tags, or verified business profiles.
How can I block spam and robocalls in Japan?
Consumers in Japan can register their numbers with the official statutory registry, Specified Commercial Transactions Act Telemarketing Rules (opens in a new tab), to legally restrict cold sales calls. Additionally, network operators such as NTT Docomo, KDDI (au), SoftBank offer call filtering tools, and suspicious activity can be escalated to Ministry of Internal Affairs and Communications (MIC).
Are numbers from Japan toll-free?
Toll-free and freephone status depends on designated non-geographic prefixes within the national numbering plan (such as 800 or 0800 ranges). Standard geographic and mobile numbers incur normal provider airtime rates, and international rates apply when calling from outside Japan.
Where can I report phone fraud or scams in Japan?
Victims of telephone fraud or persistent harassment can file an official complaint with the national scam reporting agency, National Police Agency / Consumer Affairs Agency (opens in a new tab), or submit regulatory grievances to Ministry of Internal Affairs and Communications (MIC) (opens in a new tab).
