We realized that many people likely have these questions, so we decided to compile this article.

We'll thoroughly explain the best ways to connect to the internet: traditional physical SIM cards and the easy and convenient eSIMs. We'll cover their pros and cons, and most importantly, specifically where you can purchase them and what plans we recommend.

Why Do You Need Internet in Fukuoka? Specific Scenarios for Travelers

Navigation with Map Apps

When you're in an unfamiliar place like the bustling streets of Tenjin, the complex underground malls around Hakata Station, or accessing Dazaifu Tenmangu Shrine a bit outside the city, map apps like Google Maps are indispensable. You can not only search for routes to your destination but also check real-time transfer information for buses and trains.

Gathering Information on Restaurants and Tourist Spots

Need to find a delicious Hakata ramen spot right now? Wondering about a tourist attraction's opening hours? Or want to know about today's events? With internet access, you can quickly search review sites and official information. You can also check the crowd status of popular places to make the most of your time.

Sharing Updates on Social Media

Instantly upload photos of your travel experiences and delicious meals to Instagram or Facebook to share your travel joys with friends and family in real-time. You can even live stream the atmosphere of Fukuoka.

Using Translation Apps

When interacting with people in Fukuoka, you might encounter language barriers. However, with a translation app, smooth communication is possible. You can enjoy ordering at food stalls or having casual conversations with shop staff.

Searching and Booking Transportation

You can access all kinds of transportation information, including searching subway and bus timetables within Fukuoka city, checking Shinkansen (bullet train) and flight reservation statuses, and arranging car rentals. Mobile payment options are also increasing, making transactions smoother.

Emergency Communication

In the unlikely event that you feel unwell or get into trouble, internet access is crucial as a lifeline to immediately contact family, your embassy, or emergency services.

Internet Network Stability in Fukuoka

There are four major telecommunication carriers in Japan. In Fukuoka Prefecture, especially within Hakata city, all four of these major carriers offer stable communication. However, as of 2025, if you venture into more rural areas compared to Tokyo or Osaka, networks like Rakuten Mobile may have weaker signals. While staying in major cities, including Fukuoka, you should be fine regardless of which company's network you use. However, if you plan to stay in rural areas, purchasing an eSIM or SIM card that uses the Docomo network is recommended for stable communication.

Docomo

Network Characteristics: Docomo boasts Japan's largest number of base stations and extensive coverage. It's known for high-speed and high-quality communication, with active 5G deployment. It has a strong advantage in stable, high-speed communication in urban areas.

Rural Network Stability: This is the most stable network. It offers reliable connectivity across a wide range of areas nationwide, including mountainous regions and remote islands, and you can expect relatively high-speed communication even in rural areas.

KDDI (au)

Network Characteristics: Au excels in high-speed communication and tends to have high connection stability, especially in underground malls and high-rise buildings. Its 5G area is also rapidly expanding.

Rural Network Stability: It's stable, second only to Docomo. Connectivity is reliable in major tourist destinations and regional cities, but it may be inferior to Docomo in some sparsely populated areas. It utilizes "platinum band" frequencies to cover a wide range.

SoftBank

Network Characteristics: SoftBank specializes in high-speed, large-capacity communication in urban areas. Its 5G area is expanding rapidly. It's popular among younger demographics and business users. It may also perform better in congested areas like event venues compared to other carriers.

Rural Network Stability: It tends to be slightly less stable than other major carriers. In mountainous and agricultural areas further from urban centers, there may be more locations where signals are weak. However, SoftBank has been actively improving its base station infrastructure in rural areas, showing an improving trend.

Rakuten Mobile

Network Characteristics: Rakuten Mobile is a newer telecommunication carrier with a strong focus on high-speed, high-capacity communication in urban areas.

Rural Network Stability: This carrier is most likely to have weak signals in mountainous and rural areas away from urban centers.

Additional Notes

All carriers are expanding their 5G areas, but deployment is primarily concentrated in urban centers, and 4G LTE remains the mainstream in rural areas. It's currently unrealistic to expect widespread high-speed 5G communication across Japan, as infrastructure is still developing in many places. For stable communication, 4G/LTE is currently the most reliable.

For specific signal conditions in your travel destination, it is most accurate to check the service area maps provided on each carrier's official website.

How to Get Internet Access in Fukuoka

There are several ways to get internet access in Fukuoka. While Pocket WiFi rentals are available at Fukuoka Airport, the most practical options for travelers are primarily physical SIM cards and eSIMs. You can also purchase SIM cards and eSIMs directly in Hakata City. Understand the features of each to choose the best method for your travel style.

Physical SIM Card

This is the traditional type of SIM card inserted into your smartphone. Many travelers use physical SIM cards, and a wide range of plans are available.

Pros

• Wide Range of Options: Various data plans are available depending on data volume and validity period.
• In-person Assistance: When purchasing at electronics stores or airport counters, you can consult staff for assistance, which can be reassuring.

Cons

• Requires SIM Card Swap: You'll need to remove your smartphone's existing SIM card and insert the Japanese one.
• SIM Card Storage: You'll need to carefully store your home country's SIM card after removing it from your smartphone to avoid losing it.

• You may be asked to show your passport.

eSIM: Easy and Convenient

An eSIM is a digital SIM embedded directly into your smartphone, eliminating the need for a physical card swap. You can start using it simply by purchasing and downloading a plan online, making it an incredibly convenient option for travelers.

Pros

• No Physical SIM Card Needed: No worries about losing or damaging a SIM card, and no need to open the SIM tray.
• Online Purchase Possible Before Arrival: You can purchase and set up an eSIM plan online even before arriving in Japan, allowing you to use the internet immediately upon arrival.

• Easy Switching Between Plans: You can store multiple eSIM profiles on your device and easily switch between them as needed.
• Can Be Used with Existing SIM (Dual SIM): If your phone supports dual SIM, you can keep your home country's physical SIM card inserted while using the Japanese eSIM simultaneously.

Cons

• Requires eSIM-Compatible Device: Not all smartphones support eSIM. You must check compatibility in advance.
• No In-person Support: Since purchases and setup are done online, in-person support for troubleshooting isn't typically available.

Where to Buy an eSIM in Fukuoka

Since eSIMs are not physical cards, it's generally recommended to purchase them online. While eSIMs may be advertised at airports or electronics stores, the actual activation process is done online.

Recommended eSIM Plans and How to Choose

There are four major telecommunication carriers in Japan. While any carrier's network should be fine if you're staying in prefectural capitals in Kyushu, including Fukuoka, communication quality might not be optimal in more rural areas depending on the network. For stable communication in rural areas, an eSIM that uses Docomo's network is recommended.

Recommended eSIM Plans for Your Japan Trip

Here are some eSIM plans particularly recommended for your Fukuoka trip. These plans offer reliable connectivity not just in Fukuoka, but throughout Japan.

eSIM Purchase to Setup

If you're new to eSIMs and feeling a bit unsure, don't worry! You can easily set it up by following the steps one by one.

1. Check eSIM Compatibility of Your Device

First, confirm if your smartphone supports eSIM. Most newer models (like iPhone XS and later, Pixel 3 and later) are compatible, but it's always a good idea to check your smartphone's official website or product specifications to be sure.

Example of How to Check:

• For iPhone: Go to "Settings" → "General" → "About" and look for "Available SIM" or "EID."
• For Android: Go to "Settings" → "Network & Internet" → "SIMs" or "Mobile Network" and look for "Add SIM" or "eSIM."

2. Purchase Your eSIM Plan

Refer to our "Recommended eSIM Plans for Japan Travel" and purchase the eSIM that best suits your needs.

Step 3: Install (Set Up) Your eSIM

If Using a QR Code (Easiest Method)

1. Connect to Wi-Fi and open your smartphone's "Settings."
2. Select "Mobile Data" or "Cellular."
3. Tap "Add eSIM" or "Add Cellular Plan."
4. A QR code scanner will launch. Scan the QR code you received after purchase.
5. Follow the on-screen instructions to activate your eSIM. Naming the profile (e.g., Japan eSIM) can help with management.
