Sakura Mobile Monthly Pocket WiFi: A Complete Guide for Japan Residents

If you're an expat, student, or long-term resident in Japan, getting internet isn't as simple as it should be. Many major carriers require long-term contracts, in-person visits, and paperwork in Japanese, which can make getting connected slow and frustrating.

Sakura Mobile's Monthly Pocket WiFi is designed for this exact situation. It offers a simple, no-contract internet solution in Japan for international residents and long-term visitors, with reliable connectivity and no language barriers.

In this guide, you'll learn how Pocket WiFi works, which plan to choose, how the network performs, and how to order.

What Is Sakura Mobile's Monthly Pocket WiFi?

A Pocket WiFi is a small device you carry with you. It connects to Japan's mobile network and creates a personal WiFi hotspot. Your phone, laptop, tablet—anything with WiFi—connects to it just like it would at home. No cables, no wall socket, no installation.

With Sakura Mobile's Monthly Pocket WiFi, you're renting the device—not buying it. You pay a monthly fee for as long as you need it. When you're done, you return it in the prepaid envelope that comes in your package. No hardware to buy, no multi-year contract to sign.

This is different from Sakura Mobile's short-term Travel Pocket WiFi, which is made for tourists staying just a few days or weeks. The Monthly Plans are for people who need internet for a month or more—a student on a school year, an expat getting settled in a new apartment, a remote worker on a long stay.

The device comes ready to use right out of the box. Turn it on, connect your device, and you're online. No settings to change. No SIM card to install.

Quick Specs: The device is 74 x 74 x 17 mm—about the size of a drink coaster. Battery life: up to 20 hours.

Sakura Mobile Monthly Pocket WiFi Plans & Pricing

Sakura Mobile has two Monthly Pocket WiFi plans. Both use the SoftBank 4G LTE network. The only difference is how much data you get each month. Pick the one that matches how you use the internet.

There is also a one-time activation fee of 5,500 yen (tax included) when you sign up. You only pay this once, no matter which plan you choose.

Ways to pay less:

• Student Discount: If you're a student, you can get 1,100 yen off the activation fee. Just upload a valid student ID when you apply and enter the coupon code studentdiscount at checkout.
• Bundle with a SIM: Order a Sakura Mobile Monthly Voice + Data SIM plan at the same time as your Pocket WiFi, and the Pocket WiFi activation fee is waived completely.

💡 Need more than 200 GB? Contact Sakura Mobile directly.

Billing & Payment Cycles

Your monthly usage fees are invoiced at the end of the following month, with payment timing determined by your chosen method:

• Credit/Debit Card: Fees are automatically charged at the end of the month following usage (e.g., March usage is charged at the end of April).
• Smart Pit (Convenience Store): Fees are invoiced at the end of the month, and are payable between the 1st and 10th of the subsequent month (e.g., March usage is payable between May 1st-10th).

Network, Coverage & Speed

Sakura Mobile's Monthly Pocket WiFi runs on the SoftBank 4G LTE network—one of Japan's big three national networks. It covers the whole country:

• Big cities, like Tokyo, Osaka, and Sapporo
• Suburbs
• Rural areas

Some providers advertise huge speed numbers like 988 Mbps. But those are theoretical maximums—you almost never hit them in real life. What matters more is that Sakura Mobile's devices are set up to work natively on Japan's LTE network. For everyday use—video calls, streaming, working online, getting directions—4G LTE is more than fast enough.

🏠 Need unlimited home internet? The Monthly Pocket WiFi is made to be portable and flexible. If you need uncapped data for a fixed home setup, check out Sakura Mobile's Home WiFi and Fiber Internet options instead.

Device Specs & Setup—What to Expect When It Arrives

Sakura Mobile's long-term Pocket WiFi is built for portability and all-day use. The device is compact (74 x 74 x 17 mm). It fits in a jacket pocket or the front pouch of a backpack. The battery lasts up to 20 hours on a single charge—enough for a full day without plugging in. Charging it overnight is all you need.

It works with any WiFi-enabled device, including iPhones, Android phones, laptops, tablets, and game consoles. You don't need to change any settings on your phone or computer—just connect like you would to any WiFi network. The device supports up to 15 devices at the same time, so a family can share one connection while one person is on a video call, another is streaming a show, and someone else is working.

How to Connect for the First Time

• Turn it on using the button on the side.
• Find the WiFi name (SSID)—it's printed on the sticker on the back of the device.
• Enter the password (WPA Key)—also on the back sticker. Or scan the QR code to connect instantly without typing.
• That's it! You're online!

💡 The device is fully set up before it ships. There are no Japanese menus, no SIM card to insert, and no account to create on the device itself.

Protecting Your Device—Pocket WiFi Insurance Options

Sakura Mobile offers optional Pocket WiFi insurance to protect against loss or damage. Adding insurance helps reduce or eliminate replacement costs.

What You'd Owe for Each Item

This table shows the exact fee for each item in the set, based on your insurance level:

Does Premium Insurance make sense? At 440 yen/month, it costs about 5,280 yen over a year. That's less than one-fifth of the 30,000 fee for a lost device. For most people, it's worth it.

You choose your insurance level when you apply. You can pick No Insurance, Regular, or Premium. You can't add insurance after a loss or damage has already happened, so choose at sign-up.
