Anonymous SIM Card Delivery
to Japan — No ID, No Registration

Japan has some of the strictest SIM registration requirements in Asia. Since 2015, every SIM card purchased in Japan — prepaid or postpaid — requires identity verification under the Act on Prevention of Transfer of Criminal Proceeds. Foreign visitors must present a valid passport. Japanese residents must present a My Number card or residence card (zairyu card). The requirement is enforced at point of sale and verified against carrier databases.

The practical consequence: if you want a Japanese mobile number, you hand your passport to a carrier representative, they photograph or scan it, and a permanent record links your identity to that number. For privacy-conscious users, visitors who don't want their passport details stored with a carrier, and AI developers who need a Japanese number without an identity trail, this is a hard blocker.

Simbotica ships a pre-activated, KYC-free physical SIM card directly to any address in Japan. No passport. No ID. No carrier registration. The SIM arrives ready to insert and use.

Japan's SIM Registration Law in Practice

The Act on Prevention of Transfer of Criminal Proceeds requires operators to verify identity before activating any SIM. For foreign visitors, this means presenting a valid passport — tourist SIMs at convenience stores (7-Eleven, FamilyMart) or electronics retailers (Yodobashi Camera, Bic Camera) all require it. Even data-only SIMs like IIJmio, LINEMO, and povo require document verification for Japanese residents via My Number card or residence documentation.

The data collected — name, nationality, passport number, date of birth — is retained by the carrier. Japanese law permits law enforcement access under judicial process.

Shipping to Japan

Simbotica ships to all Japanese prefectures via international tracked post. Delivery to mainland Japan (Honshu, Kyushu, Shikoku, Hokkaido) and island prefectures (Okinawa) typically takes 7–12 business days. Japan Post and yamato (kuroneko) delivery to convenience store pickup (combini ukewatashi) is supported for most addresses.

Japanese customs: a single SIM card is a low-value personal electronic item with no import restriction. No duty applies at individual quantities.

Network Coverage in Japan

In Japan, the Simbotica SIM connects to the strongest available network in your location. Japan's main networks — NTT Docomo, SoftBank, and au (KDDI) — provide near-complete coverage across urban and rural areas. Docomo has the broadest rural and mountain coverage; SoftBank and au are strongest in urban centres. Rail corridors and major highways have consistent coverage from all three.

Use Cases for Japan

Tourists and long-stay visitors: You need a Japanese number for account registration on Japanese platforms (LINE, Mercari, Rakuten, PayPay) without surrendering your passport details to a mobile carrier. A Simbotica SIM gives you a real Japanese mobile number without that exchange.

Privacy-conscious Japan residents: You want a secondary number not linked to your My Number card or residence documentation — for classifieds (Jimoty, Mercari), delivery services, or any platform where you don't want your primary number associated with your activity.

AI agent developers targeting Japanese platforms: Your agent needs to verify on a Japanese platform that requires a Japanese mobile number. LINE, Mercari, PayPay, and most Japanese e-commerce platforms use SMS OTP as a hard verification gate. A Simbotica SIM provides a real Japanese number without any account or identity requirement.

Business travellers: You need a Japanese number for a short engagement without committing to a carrier contract or providing passport details for a temporary SIM.
