What is Sakura Mobile?

Founded in 2014, Sakura Mobile is a Japanese telecommunications provider specifically designed for foreign residents and tourists in Japan,often providing more stable connections and better localized support than international eSIM resellers. Their primary goal is to eliminate the language and bureaucratic barriers that often make getting mobile service in Japan difficult for non-Japanese speakers.Their products include rental pocket Wi-Fi devices, data-only SIM cards, eSIMs, and monthly voice and data plans.They are a MVNO (Mobile Virtual Network Operator), meaning they don't own their own physical wireless network. Instead, they rent capacity from major carriers. Sakura Mobile operates on the NTT DOCOMO network, which is renowned for having the best coverage and reliability across Japan, including rural areas.Now,Sakura Mobile has became one of the most popular choices among international travelers thanks to its stable network, unlimited data plans, and excellent English-language support.

Key Characteristics of Sakura Mobile

1. Target Audience: Foreigners

This is their core focus. Everything from their website to customer support is tailored for non-Japanese:

• Full English Support: Their customer service is available in English via phone and email.

• Simple Requirements: They streamline the sign-up process, which is a significant advantage in Japan where standard contracts can require complex resident registration.

2.Key Advantages

• Top Network Coverage: By utilizing the NTT Docomo network, they offer some of the most extensive and fast 4G and 5G coverage throughout Japan, including on the Shinkansen (bullet trains) and in many subway stations.You won't lose connection in mountainous regions or small towns.

• Convenience: Tourists can order an eSIM online before they arrive and have internet the moment they land. Residents can get a functional phone number quickly without fluent Japanese.

• No Complex Registration: They handle the compliance with Japanese telecom regulations on your behalf, making the process much smoother than going directly with a major Japanese carrier.

• Flexible Contract Terms: They offer both short-term (for tourists) and long-term (for residents) plans, many without a strict long-term contract.

• Hotspot Support: You can tether on both iOS and Android (depending on plan).

• Convenient Pick-up/Delivery: You can often choose to have your SIM/Pocket Wi-Fi delivered to your hotel or pick it up at a counter in major international airports (like Narita, Haneda, and Kansai).

3. Potential Drawbacks

• Price: They are generally more expensive than mainstream Japanese carriers or some other MVNOs. You are paying a premium for the English support and convenience.

• Data Speeds: As an MVNO, their data speeds can sometimes be slower during peak congestion times compared to direct Docomo customers (a practice called "bandwidth throttling"). However, for typical tourist use (maps, web browsing, social media), this is rarely an issue.

Who is Sakura Mobile For?

• Tourists & Short-Term Visitors: Their eSIM and Tourist SIM plans are ideal for anyone needing reliable data without the hassle of picking up a SIM at the airport. The ability to set it up before arrival is a huge plus.

• New Foreign Residents: For those who have just moved to Japan, Sakura Mobile is a perfect "starter" service. It provides a crucial Japanese phone number and data immediately, allowing you to get settled without the language barrier. Many people use it for their first few months before switching to a cheaper provider once they are more established.

• Students & Workers on Medium-Term Stays: Anyone staying for 6 months to a few years who values English support and a straightforward process.

How to Purchase and Install?

The process is fully digital and can be completed before you leave home.

Step 1: Check Compatibility

To use Sakura eSIM, your phone must be:

1. eSIM-compatible

Before purchasing, ensure your device is eSIM-compatible. Most modern smartphones (iPhone XS/XR and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer) support eSIM.Go to your phone's settings to confirm eSIM support.

iPhone: iPhone XS, XR, or newer (including all iPhone 11, 12, 13, 14, 15 models and SE 2nd & 3rd generation). Go to Settings > General > About. If you see an "EID" listed, your phone supports eSIM.

Android: Many newer models from Google Pixel, Samsung Galaxy, Motorola, and others support eSIM. Check your manufacturer's website or look for "EID" in your Settings > About Phone menu.

Dial *#06# → If an EID number appears, your device supports eSIM.

2.Unlocked

Ensure your phone is not locked to a specific carrier. You can usually contact your home carrier to confirm this.Carrier-locked phones will not work.

3.Support Japan network bands

Japanese networks use specific LTE/5G bands. Most modern, unlocked phones support the necessary bands, but it's good to verify. Sakura Mobile (using DOCOMO) primarily uses Band 1 (2100 MHz), Band 19 (800 MHz), and Band 21 (1500 MHz).

Step 2: Choose and Purchase Your Plan

Visit the Sakura Mobile website, select your desired plan (data size and duration), and complete the payment.

2. Select eSIM Plan: Choose the "eSIM" section and select the data plan that best fits your travel duration and data needs.

3. Checkout: Proceed to checkout. You will need to provide your email address and pay with a credit/debit card.

6. Important: Set "Data Mode" to Allow More Data on 5G or Standard and make sure your Primary line (your home number) is selected for "Cellular Data Switching" if you want to use your home plan as a backup.

7. To ensure it uses the Sakura eSIM for data, go to Settings > Cellular > Cellular Data and select the Sakura Mobile plan as your primary data line.

8. Activation: The eSIM should activate automatically once you are in Japan and connected to the DOCOMO network. You may need to turn on "Data Roaming" for this line in your cellular settings.
