Setting up an internet and phone plan in Japan can feel like stepping into a maze of unfamiliar options, technical jargon, and complex contracts. As a newcomer, you might find yourself wondering: How do I choose the best provider? What’s the difference between fiber-optic and pocket Wi-Fi? Are there hidden fees I should watch out for? These are questions nearly every first-time renter in Japan faces.
When I first arrived in Japan, I knew there would be challenges—adapting to the culture, learning the language, figuring out daily life. But I didn’t expect that something as simple as setting up the internet and a phone plan would be one of the most frustrating hurdles.
My husband, despite being half Filipino-Japanese, wasn’t much help either. He was born in the Philippines and had only moved to Japan a few years ahead of me. He was also still transitioning, learning Japanese, and—just like me—struggling to read Kanji. So, when it came time to get our internet and phone plans, we were both completely lost.
We walked into a store, hoping to figure things out together. The staff was polite, but the moment they handed us a thick stack of forms, we froze. The contracts were packed with complicated Kanji, and even with Google Translate, we could barely make sense of them. Every time we asked a question, the staff would reply in rapid Japanese, pointing at different sections of the contract as if that would somehow make things clearer. We left the store more confused than when we entered.
After multiple failed attempts at different providers, we finally realized that we needed a different approach. We started searching for English-friendly internet providers in Japan, reading through forums, and watching YouTube videos from foreigners who had gone through the same struggle. Eventually, we found a provider with an English customer service line. That one call changed everything. The representative walked us through the process, explained the key terms, and even helped us fill out the application.
That experience taught us a valuable lesson: in Japan, information isn’t always easily accessible in English, but that doesn’t mean solutions don’t exist. Whether it’s finding English-friendly providers, using translation apps strategically, or asking for help in foreign communities, there are ways to navigate these challenges.
If you’re a newcomer, especially one who can’t read Kanji yet, don’t get discouraged. The process might be frustrating at first, but with the right resources and a bit of patience, you’ll get there—just like we did!
In this guide, I’ll walk you through everything you need to know about setting up internet and phone plans in Japan. From understanding the different types of services to comparing providers and avoiding common pitfalls, this blog will equip you with the tools to make informed decisions. Let’s simplify the process and get you connected without the stress!

At first, I was overwhelmed by the internet options. I opted for a pocket Wi-Fi device due to its flexibility. However, I soon realized that for multiple devices, streaming and video calls, a fiber-optic connection was more suitable. After researching, I chose a long-term plan with a reputable provider, ensuring reliable and fast internet access.

IV. Navigating the Application Process Without Japanese Fluency
Setting up an internet and phone plan in Japan as a foreigner who isn’t fluent in Japanese can feel overwhelming, especially when faced with contracts full of kanji and customer service representatives who may not speak English. But don’t worry—there are ways to navigate this process smoothly, even if you’re still learning the language. Let’s go through the key requirements and practical strategies to help you get connected hassle-free.
1. Required Documents for Sign-Up
Before applying for an internet or phone plan, you’ll need to prepare some important documents. These requirements vary slightly depending on the provider, but most will ask for the following:
• Residence Card (在留カード, Zairyū Kādo) – This is your primary form of identification as a foreign resident in Japan. Most service providers require it to confirm your residency status.
• Passport (パスポート, Pasupōto) – Some companies might ask for your passport as additional identification.
• Japanese Bank Account (銀行口座, Ginkō Kōza) – Many providers prefer or require automatic payments from a local bank account. If you don’t have one yet, some companies allow payments via credit card.
• Personal Seal (印鑑, Inkan) – While not always necessary, some providers (especially traditional ones like NTT Docomo and SoftBank) may ask for an inkan for official contracts.
• Japanese Address (住所, Jūsho) – You’ll need a valid address in Japan, as many providers will send your contract or rental equipment by mail.
📌 Tip: If you’re in Gifu and need assistance gathering these documents, there may be an English-speaking staff at your city hall who can often help direct you to the right offices.
2. Strategies for Overcoming Language Barriers
If you don’t speak Japanese fluently, navigating contracts, websites, and in-store interactions can be challenging. Here are some strategies to help:
💡 Use Online Translation Tools
• Google Translate’s Camera Feature: Scan Japanese text instantly to get a rough translation of contracts or application forms.
• DeepL Translator: More accurate than Google Translate for longer text passages, especially for contracts.
📞 Seek English-Speaking Customer Support
Some providers offer English-language services, but availability varies. Based on our earlier research:
• Rakuten Mobile and IIJmio have English support for online applications.
• SoftBank’s Global Rental Services cater to foreigners but may be pricier than standard plans.
🤝 Bring a Japanese-Speaking Friend or Use Interpretation Services

Personal Experience in Setting Up Internet and a Phone Plan
When I first moved to Gifu, I was excited to set up my internet and phone plan—until I realized that everything was in Japanese. My husband, who is half-Filipino, half-Japanese, had only been in Japan a few years longer than me, and even he struggled with kanji-heavy contracts.
We first tried going to a SoftBank store, but the staff only spoke Japanese, and the contract documents were overwhelming. Since we couldn’t understand the fine print, we left without signing up. Frustrated, we turned to Rakuten Mobile instead. Their website had an English option, and the sign-up process was straightforward. Within a few days, I had my SIM card delivered to the apartment.
For the internet, we initially thought about getting fiber internet (光回線, Hikari Kaizen), but since contracts were long-term, we opted for pocket Wi-Fi from a store at Bic Camera instead. The staff didn’t speak English, but with Google Translate and some persistence, we managed to get everything set up.
Looking back, I wish I had known about international centers in Gifu that offer free support for foreigners. If you’re in a similar situation, definitely check them out!
Navigating Japan’s internet and phone plan application process without Japanese skills can be a challenge, but it’s definitely manageable with the right approach.
Key takeaways:
✅ Prepare essential documents like your residence card and bank account.
✅ Use English-friendly providers like Rakuten Mobile and Asahi Net.
✅ Take advantage of translation apps, city hall support, or help from friends.
✅ If you’re unsure about a contract, don’t sign anything until you fully understand it.
By planning ahead and using the resources available to you, you can get connected smoothly—without needing perfect Japanese.
V. Tips for Managing Your Internet and Phone Services
Staying connected in Japan requires more than just choosing the right plan—you also need to manage your services efficiently. Here’s how you can monitor your usage, handle plan renewals, navigate customer support despite language barriers, and save money with smart bundling options.
1. How to Monitor Usage and Avoid Extra Charges
One of the biggest concerns when using mobile and internet services in Japan is exceeding your plan’s limits. Overuse can lead to additional charges or speed restrictions, so it’s important to keep track of your data and call usage.
✔ Use Carrier Apps – Most mobile providers in Japan offer apps to monitor your usage in real time. Here are some options:
• NTT Docomo – My docomo
• au by KDDI – au PAY
• SoftBank – SoftBank My Menu
These apps allow you to check your remaining data, set up alerts, and even change your plan if needed.
✔ Check Usage in Device Settings – Both iPhone and Android devices provide built-in data usage monitoring:
• iPhone: Go to Settings > Cellular > Cellular Data Usage
• Android: Go to Settings > Network & Internet > Data Usage
✔ Use Third-Party Apps – Apps like My Data Manager help track your data consumption and identify which apps use the most data.
✔ Set Up Alerts – Many carriers allow you to set notifications when you’re nearing your data limit. Enabling these alerts can prevent unexpected charges.
2. Renewing, Cancelling, or Switching Plans
Whether you’re staying long-term or just for a short period, understanding how to modify your plan is essential.
📌 Renewing Your Plan
• Most postpaid contracts automatically renew unless canceled. However, it’s always a good idea to check your provider’s policy to avoid surprises.
• Prepaid plans often require manual renewal, so set a reminder before your plan expires to avoid service interruptions.
📌 Canceling Your Plan
• To cancel, visit your provider’s store or contact customer service. Some providers require you to cancel in person.
• Be aware of early termination fees, especially if you’re in the middle of a fixed-term contract. For example, some two-year contracts charge penalties if canceled before the end of the period.
• SIM-only plans from providers like IIJmio and Rakuten Mobile tend to have more flexible cancellation policies.
📌 Switching Plans or Providers
• If you’re unhappy with your current plan, consider switching to a provider that better suits your needs.
• Japan has a Mobile Number Portability (MNP) system that allows you to transfer your phone number between carriers. You’ll need to request an MNP reservation number from your current provider before switching.
3. Handling Customer Support Without Fluency in Japanese
Language barriers can make dealing with customer support a challenge. Here’s how to get the help you need:
✔ Use English-Support Providers – Some providers offer customer service in English:
• Rakuten Mobile – English Support
• SoftBank – English Customer Service
• IIJmio – English FAQ & Support
✔ Use Online Chat Support – Some companies provide chat support, where you can type in English, and they translate responses.
✔ Bring a Japanese-Speaking Friend – If visiting a store, having a fluent friend with you can be helpful.
✔ Use Translation Apps – Apps like Google Translate or VoiceTra can assist with translating conversations.
✔ Check Online Communities – Forums like Reddit’s r/JapanLife or GaijinPot Forums often have answers from fellow foreigners in Japan.
4. Saving Money with Bundled Services or Promotions
Many providers offer discounts if you bundle multiple services together. Here’s how you can cut costs:
📌 Bundling Mobile and Home Internet – Many major carriers provide discounts if you use both their mobile and fiber-optic internet services:
• SoftBank offers a bundle discount for using their mobile and internet services together.
• au by KDDI provides a Smart Value Plan for customers who combine au Mobile with their fiber-optic internet.
📌 Family Plans – If you have multiple phone lines in your household, consider a family discount plan. Providers like NTT Docomo and SoftBank offer savings for families using the same carrier.
📌 Seasonal Promotions – Keep an eye on new customer discounts, which are often available in March (the start of Japan’s school and work year) and September. Some companies waive activation fees during these periods.
📌 Using MVNOs (Budget SIM Providers) – Instead of major carriers, you can opt for low-cost SIM providers like Mineo or IIJmio, which use big carriers’ networks but offer cheaper plans.
Final Thoughts: Staying Connected in Japan with Confidence
Moving to Japan or even just staying for an extended period comes with its fair share of challenges, but getting your internet and mobile services set up doesn’t have to be one of them. With the right information, you can confidently choose a plan that fits your needs, whether you’re settling down long-term or just visiting for a while.
While navigating contracts, language barriers, and hidden fees can feel overwhelming, remember that you’re not alone—there are services, resources, and communities that can help. Take your time to research, compare options, and ask for assistance when needed. The more informed you are, the smoother your experience will be.
Most importantly, don’t let the technicalities of staying connected take away from the incredible experience of living in Japan. Whether you’re working, exploring, or staying in touch with loved ones back home, the right internet and phone plan will give you the freedom to enjoy every moment without unnecessary stress.
So, go ahead—stay connected, embrace the adventure, and make the most of your time in Japan!
