A Complete Guide to SIM Cards and Pocket Wi-Fi in Tokyo

Staying connected is essential when traveling in Tokyo. From using maps and translation apps to sharing your journey on social media, having reliable internet access can make your trip smoother and more enjoyable. Fortunately, Japan offers several convenient options for visitors, including SIM cards and pocket Wi-Fi.

In this guide, we explain the differences between these options, how to choose the best one for your trip, and where to get them in Tokyo.

SIM Cards in Tokyo

A SIM card is a popular choice for solo travelers who want a simple and lightweight solution. Tourist SIM cards in Japan are typically data-only, meaning voice calls are not included, but apps like WhatsApp, LINE, or Skype work perfectly for communication.

Pros of SIM Cards

• No extra device to carry
• Easy to use once installed
• Ideal for solo travelers
• Generally cheaper for short stays

Cons of SIM Cards

• Requires an unlocked phone
• Usually data-only (no phone number)
• Cannot be shared with others

SIM cards are available in different data amounts and durations, such as 7, 14, or 30 days.

Pocket Wi-Fi in Tokyo

Pocket Wi-Fi is a portable router that provides internet access to multiple devices at once. It is especially popular with families, couples, or groups traveling together.

Pros of Pocket Wi-Fi

• Can connect multiple devices
• Works with any phone (no unlocking required)
• Stable and fast connection

Cons of Pocket Wi-Fi

• Needs to be charged daily
• One more device to carry
• Slightly more expensive than SIM cards

Pocket Wi-Fi is a great option if you plan to share internet access or use multiple devices such as phones, tablets, and laptops.

SIM Card vs Pocket Wi-Fi: Which Should You Choose?

Choosing between a SIM card and pocket Wi-Fi depends on your travel style.

• Solo travelers: SIM card
• Couples or groups: Pocket Wi-Fi
• Short stay: SIM card
• Multiple devices: Pocket Wi-Fi

If you want convenience and minimal luggage, a SIM card is often the best choice. If you value flexibility and sharing, pocket Wi-Fi may be more suitable.

Where to Buy SIM Cards and Pocket Wi-Fi in Tokyo

Visitors can easily obtain both options at major entry points and around the city.

• Airports: Narita and Haneda Airports offer SIM cards and pocket Wi-Fi rental counters.
• Electronics stores: Shops like Bic Camera and Yodobashi Camera sell tourist SIM cards.
• Online reservation: Many travelers reserve SIM cards or pocket Wi-Fi in advance and pick them up at the airport or have them delivered to hotels.

Advance reservation is recommended during peak travel seasons to ensure availability.

Tips for Staying Connected in Tokyo

• Make sure your phone is SIM-unlocked before arriving in Japan.

• Download offline maps as a backup.
• Check coverage details if you plan to travel outside Tokyo.
