Summary

Rakuten Mobile will stop service and automatically cancel lines that are not linked to a Rakuten ID by the end of November. The company began notifying users in late August via its website and has also emailed affected subscribers. All services—including calls and data—will be unavailable if the ID is not linked in time. New customers since around December last year already had to link an ID, so most recent sign-ups are unaffected. This is part of Rakuten’s strategy to integrate users into its ecosystem and expand benefits like Rakuten Points. If you’re an expat or student in Japan, act early to avoid losing service at a critical moment. Create or link your Rakuten ID via the Rakuten Mobile app or website and confirm your line details. Considering a carrier switch? Initiate any number transfer before cancellation to avoid losing your number. Click to read what to do step-by-step and why this policy matters now.

Deadline set: Link your Rakuten ID or lose service

Rakuten Mobile has announced that subscribers who do not obtain and link a Rakuten ID will have their mobile service stopped and their contracts automatically cancelled by the end of November. The company said by September 4 that the requirement applies to existing users who have not yet linked an ID, adding that it began public notices on its website in late August and has also emailed targeted customers directly. According to Rakuten Mobile, all services—including voice calls and data—will become unavailable if an account is not linked in time. New customers have been required to link a Rakuten ID since around December last year.

Why the push? Building a seamless “Rakuten Economy”

The move is designed to bring mobile users into Rakuten Group’s broader ecosystem, often dubbed the “Rakuten Economy,” where a single ID connects shopping, finance, travel, and content services. For consumers, this integration can mean simplified logins, unified billing, and the ability to earn and redeem Rakuten Points—one of Japan’s most popular loyalty programs—across daily life, including offsetting mobile bills. For Rakuten, it supports cross-service engagement and stronger account security, while helping the carrier scale efficiently in Japan’s intensely competitive telecom market.

Who is affected—and who is not

Existing Rakuten Mobile subscribers who never created or linked a Rakuten ID are the ones who must act before the deadline. Customers who signed up from around December last year are generally unaffected because linking a Rakuten ID has already been mandatory for new contracts. Rakuten says that lines without a linked ID will lose access to all mobile services if no action is taken by the end of November, followed by automatic cancellation.

What users should do now

Current users should log in to the Rakuten Mobile app or website and confirm that their mobile line is linked to a Rakuten ID. If you do not yet have a Rakuten ID, you can create one free of charge on Rakuten’s official site, then complete the linkage in your account settings. Watch for emails or in-app messages from Rakuten Mobile with account-specific instructions. If you encounter issues—such as mismatched personal details—contact Rakuten Mobile support promptly to avoid service interruption. Acting early is wise, especially if you rely on the line for two-factor authentication, banking alerts, or work communications.

Context for foreign residents in Japan

For expats, students, and long-stay visitors using Rakuten Mobile, this is part of a broader Japanese trend toward single sign-on ecosystems across mobile, payments, and e-commerce. Similar ID systems exist with other major carriers in Japan, and they underpin the country’s reputation for integrated, convenient digital services. Linking your Rakuten ID not only prevents disruption but can also unlock meaningful savings through points earned on everyday spending across Rakuten’s platforms. If you plan to change carriers instead, move early: once a contract is cancelled, you may lose your phone number, so initiate a number transfer (MNP) in advance if needed.

Big picture: A pro-consumer, pro-integration shift

Japan’s mobile market continues to evolve rapidly, with aggressive pricing, expanding 5G coverage, and tighter integration between telecom and digital services. Rakuten’s ID linkage requirement underscores a nation-wide emphasis on secure, unified accounts that enhance convenience while curbing fraud. For users, the message is clear: take a few minutes to confirm your linkage, and you’ll be better positioned to enjoy Japan’s points-driven lifestyle and the growing suite of services built around it—without risking an avoidable service cutoff.
