How to Get Internet in Japan When Traveling – Complete Tourist Guide

Traveling abroad without internet access can be incredibly frustrating. In this guide, we’ll walk you through three reliable ways to stay connected while exploring Japan. If you're planning a trip, make sure to read this before you go — a little preparation can go a long way!

Most major mobile carriers offer roaming plans for Japan, with prices and data allowances that vary by provider. These plans can usually be activated online before departure.

Pros

• Hassle-Free Setup: You can activate roaming directly through your carrier’s app or website — no need to change SIM cards or carry extra devices. The service typically kicks in automatically when you land in Japan.
• Stay Reachable: Keeping your original number active means you won’t miss important calls, texts, or banking alerts. It’s especially helpful for staying in touch with people back home or receiving two-factor authentication codes.

Cons

• Expensive: Roaming charges can quickly add up, especially if you use a lot of data. Be sure to check your carrier’s rates in advance.
• Inconsistent Performance: Roaming connections may not be as fast or reliable as local networks, particularly in rural areas or during peak usage times.
• Limited App Access: Since you're technically connected through your home network, access to certain local services or apps might be restricted.

Japanese SIM cards are available in both physical and eSIM formats. Not all phones support eSIMs, so double-check compatibility before you buy. You can order a SIM card online before your trip or purchase one at airports, convenience stores, or mobile shops once in Japan.

Pros

• Cost-Effective: Compared to international roaming, local SIMs are typically far more affordable, especially if you’re planning to use a lot of data.
• Plug and Play: Just pop the SIM into your phone and you’re connected. No additional devices or complicated setups are required.
• Fast and Reliable Network: Enjoy stable, high-speed access to local services like maps, ride-hailing apps, and restaurant recommendations — ideal for independent travelers or anyone navigating off the beaten path.

Cons

• No Access to Your Regular Number: Swapping SIMs means calls and texts to your usual number won’t come through. If this is a concern, consider using a dual-SIM phone to keep both numbers active.

Pocket WiFi devices can be reserved online in advance and picked up at the airport upon arrival. Some providers also allow for mail returns or drop-offs at alternative locations when you leave Japan.

Pros

• Easy to Use: These devices are user-friendly — just turn them on, and you’re good to go. No tech skills required.
• Great for Groups: Pocket WiFi can support multiple devices at once, making it perfect for families or groups traveling together. Share the connection and split the cost.
• Unlimited Data & Strong Signal: Most devices offer fast, stable connections with generous or unlimited data caps, ideal for streaming, video calls, and navigation throughout your trip.

Cons

• Extra Gear to Carry: You'll need to keep the device with you and remember to charge it regularly. Opt for a model with long battery life to avoid disruptions.
• Loss or Damage Risk: If the device is lost or broken, you may face a penalty fee — plus the inconvenience of being offline until it’s replaced.

Each of these options offers distinct advantages depending on your travel style, budget, and connectivity needs. Whether you're traveling solo or with a group, there’s a solution that can keep you online and make your journey through Japan smoother and more enjoyable.
