Can you buy a local SIM or eSIM in Japan without ID?
Identity verification is established for Japanese voice SIM contracts in the sources below. MIC confirms Act No. 25 of 2026 was adopted on 22 May 2026 and promulgated on 29 May. Its 3 August announcement says some implementing details are delegated to ministerial ordinances. This review has not established the current requirements for each data-only product.
22 May 2026: an amended law was adopted to extend identity checks to data SIM contracts; its application date was not found.
What is documented for a foreign travel eSIM in Japan?
Applicability of the local identification framework to a foreign-issued travel eSIM in roaming remains unverified. The MIC announcement confirms a May 2026 amendment and states that some details are delegated to ministerial ordinances; it does not establish a profile-specific roaming exemption.
Does Japan's May 2026 amendment establish the rule for my travel eSIM?
The MIC announcement confirms Act No. 25 of 2026 was adopted on 22 May and promulgated on 29 May. It describes work on the implementing framework and notes that some system details are delegated to ministerial ordinances.
That announcement alone does not establish the current activation requirements for a particular foreign-issued data profile. We therefore distinguish the known existence of the amendment from its unverified scope for inbound roaming. The earlier claim that tourists were unaffected has been removed. Before purchasing, check the exact product requirements rather than applying a rule for a Japanese voice line to every travel eSIM.
What should a visitor check before travelling to Japan?
A data-only line cannot call 110 (police) or 119 (fire and ambulance), according to Simology, an eSIM seller. Keep your home SIM active for emergency calls.
Japan's 2026 amendment may later bring ID checks to data SIM contracts. This page will be updated when the ministerial ordinances are published.
iPhone 17 models sold in Japan are eSIM-only, with no SIM tray, according to heise; the iPhone Air is eSIM-only everywhere. If you buy one there, a local physical SIM card will not fit it.
What does an UnlistedSIM plan for Japan cost?
From $2.09. Review the allowance and validity before purchasing. Minimum balance top-up: $10; unused balance is non-refundable. No phone number is included.
What else is specific to Japan?
Can I call 110 or 119 with a data-only eSIM in Japan?
No. A data-only line has no phone number and cannot call 110 (police) or 119 (fire and ambulance), according to Simology, an eSIM seller. Keep your home SIM active in dual SIM mode for emergencies, or carry a phone with a voice line. UnlistedSIM eSIMs are data only: no number, no calls, no SMS.
Where can I check the checkout and privacy limits?
