If you've just arrived in Japan or you're switching carriers from an expensive incumbent, you can open a Rakuten Mobile line completely online in English—no shop visit required, no Japanese language skills needed, no dealing with paper forms or confused staff. With eSIM + eKYC digital verification, activation can happen very fast once identity screening completes, often within the same day you apply.

What You'll Need (5-Minute Prep)

An Unlocked, Compatible Phone

Before starting your application, verify your specific device model works with Rakuten's network frequencies through the official device compatibility checker. Pay close attention to the caveats about overseas models—phones purchased outside Japan sometimes lack critical frequency bands even if the model name appears on the compatibility list.

Check specifically for Band 3 (1.7GHz) for 4G coverage, Band 28 (700MHz) for Platinum Band indoor/rural coverage, and Sub-6 5G bands if you want 5G connectivity. Many overseas phones lack Band 28, preventing you from benefiting from Rakuten's most significant coverage improvement since 2024.

Accepted ID for Digital Verification

Foreign nationals can verify identity online using a Residence Card (zairyuu kaado) or Special Permanent Resident Certificate through AI quick identity verification (eKYC). This digital process involves photographing your ID from multiple angles and taking a selfie for facial recognition matching—it works remarkably well when you follow the lighting and angle instructions carefully.

Short-term tourists typically cannot use eKYC and may need shop visits with passport verification. The system works best for residents with Japanese-issued ID documents containing addresses registered in government databases.

A Payment Method

Rakuten supports credit card or bank account for monthly billing. Credit cards prove simplest for international residents—most Visa, Mastercard, American Express, and JCB cards work fine regardless of issuing country. Bank account direct debit requires a Japanese bank account with address matching your application exactly. See payment method details in the Step-by-Step Guide.

(Optional) Rakuten ID

You can apply without a Rakuten account, but having a Rakuten ID unlocks points programs and campaign eligibility that can substantially reduce your costs. If you plan to use other Rakuten services (shopping, travel, banking), create your ID before applying. If not, you can skip this and create one during the application process. See: Apply without a Rakuten ID.

The Fast eSIM Route (Step-by-Step)

1. Start the Online Application

Open the English application page and choose eSIM for fastest activation. The system walks you through plan selection (typically the Saikyo Plan for unlimited data), optional phone purchase if you need a device, and basic information collection. Follow prompts carefully and keep your ID document handy for reference. See: Online Application Guide.

2. Pick Identity Verification Method

When prompted for verification method, choose AI quick identity verification (eKYC) for the quickest processing flow. This involves photographing your Residence Card or Special Permanent Resident Certificate from multiple angles—follow the on-screen guides for proper lighting and positioning. Then capture a selfie for facial recognition matching against your ID photo. The system processes this remarkably quickly when photos meet quality standards, but poor lighting or blurry shots trigger rejection requiring resubmission. Supported IDs listed on the ID page.

3. Enter Payment Details

Provide credit card or bank account information for monthly billing. The system validates your payment method during application—expired or invalid cards cause immediate rejection. If using an international credit card, ensure it allows recurring international billing without requiring manual authorization for each charge. See payment requirements reminder in the Step-by-Step Guide.

4. Activate Your eSIM

When screening completes—typically within minutes to hours depending on application volume and verification complexity—you'll receive notification to proceed with eSIM activation. Open the my Rakuten Mobile app on your phone and follow device-specific activation instructions. Scan the displayed QR code or manually enter profile installation details depending on your device. Initial setup and activation procedures detailed on the SIM product page and eSIM page.

Your phone downloads carrier settings and activates service within minutes of eSIM profile installation completing. You should see "Rakuten" in your signal indicator confirming successful activation.

Tips That Prevent Delays

Name & Address Must Match Exactly

Your application name must match your ID document exactly—including middle names, name order, and spelling. Your address must match precisely including apartment number format, building name exactly as shown, and district/ward names in the proper format. The ID verification page highlights common issues causing rejection: Identity verification documents.

If your residence card shows your name in both Latin alphabet and katakana, follow the guidance about which version to submit. Mismatches between your application and official ID trigger automatic rejection requiring resubmission with corrected information.

Overseas-Purchased Phones

Even if your phone model appears on the compatibility list, Rakuten specifically flags that devices purchased abroad may not fully work due to regional variants lacking specific frequency bands or carrier features. The BYOD checker shows general model compatibility—verify your specific variant includes Japanese bands before purchasing service.

Consider buying a Rakuten-certified device if your overseas phone shows compatibility concerns. While this increases upfront costs, it eliminates activation headaches and ensures full feature access including VoLTE and 5G capabilities.

Prefer a Physical SIM?

You can select physical SIM card during application instead of eSIM, receiving it by post within 2-5 days. This option works better for devices with problematic eSIM implementation or if you prefer traditional SIM cards over digital profiles. See pros and cons of each option in the Online Application Guide.

Physical SIMs add delivery delay but eliminate device-specific eSIM activation quirks that occasionally cause problems even on officially supported models.
