1. What is Pocket Wifi?

Imagine having your own personal WiFi bubble that follows you everywhere. That’s exactly what pocket WiFi is – a compact device that creates your private internet connection wherever you go. No bigger than a deck of cards, it taps into mobile networks to give your devices secure WiFi access without hunting for public hotspots. Whether you’re a traveler exploring Japan, a student on the move, or just someone who needs reliable internet without the commitment of a long-term contract, pocket WiFi keeps you connected with minimal fuss.

2. Do you need to reserve Pocket Wifi in Japan?

The short answer is yes.

When it comes to renting pocket WiFi, you have two main options:

1. Reserve your device online before leaving and pick it up at the airport upon arrival.
2. Rent a device at the airport without a reservation.

We recommend reserving online, as it’s typically more cost-effective. When you book online, you avoid the additional operational and labor costs of airport rentals, which can result in significant savings.

3. How to choose a Pocket WiFi? 5 Key Factors

With so many options, it’s essential to consider a few key points to make the right choice. Here’s what to look for:

Data Plans

You’ll notice a range of data plans that vary widely by provider when looking at mobile WiFi hotspot options. Some companies offer small daily data allowances, starting at around 100MB per day, while others provide unlimited data plans.

We recommend choosing an unlimited data plan for a worry-free experience.

Here’s why: With limited data, there’s a risk of running out when you need it most—leaving you without internet access until your daily allowance resets. Imagine losing connection mid-day, being unable to access Google Maps, translating menus, or contacting friends and family. In a foreign country, this can be stressful and inconvenient.

To make the most of your trip and avoid having to monitor your data usage, we suggest choosing an unlimited plan so you can stay connected without worry.

Pricing

While budget options might look appealing, they often come with trade-offs. Low-cost devices may suffer from:

• Slower connection speeds
• Poor battery life
• Unstable connections

We’ve carefully selected seven providers that deliver reliable WiFi service without these common issues.

English Customer Support

Having reliable English customer support can make all the difference if you experience any issues—such as losing connection, misplacing your device, or encountering technical problems. We highly recommend choosing a provider that offers dedicated English-speaking support to ensure you have help whenever you need it.

Here are two key things to look for:

• Multiple Contact Options: Look for companies that offer both phone and email support. In urgent situations, phone support allows you to speak to someone immediately. For non-urgent inquiries, email is a convenient option, giving you flexibility in how you reach out.
• Availability on Weekends: Many pocket WiFi providers don’t offer weekend support, which can be inconvenient if you’re traveling. Since issues can arise at any time, it’s best to choose a provider with support available 365 days a year.

Reviews

Check user reviews to get an idea of each provider’s reputation. Generally, highly rated providers have earned their ratings through reliable service and product quality.

4. Pocket WiFi vs SIM card

If you’re planning a trip to Japan, pocket WiFi devices and SIM cards are both popular options for staying connected. We’ve created a quick comparison below to help you decide which is best for your needs.

Why Choose Pocket WiFi? Pocket WiFi may be the right choice if you’re looking for a convenient, flexible option that allows multiple devices to stay connected:

• Easy, Immediate Access: Start using the internet right away without any setup—simply power on the device and connect.
• Shareable Connection: Great for group travel, pocket WiFi lets you share your internet connection with friends or family.
• Connect Multiple Devices: Perfect if you need internet on multiple devices, like a phone, tablet, and laptop.

Why Choose a SIM Card? A SIM card might be better if you prefer simplicity and don’t mind limiting your internet access to one device:

• No Extra Device to Carry: With a SIM card, you avoid carrying an additional router, making it a lightweight option.
• Data Only for Your Phone: Ideal if you just need data on your smartphone.
• Cost-Effective Option: Generally, SIM cards are cheaper than pocket WiFi, making them a good choice if you’re on a budget.

Sakura Mobile offers pocket WiFi and SIM card rentals to suit different travel needs. If you want to explore either option, check our website for more details.
