Internet in Japan: what you need to know
If you live alone, share a space, or spend most of your time outside, getting a home Wi-Fi plan in Japan may not be the best choice. Home internet in Japan typically costs 4,000 yen or more per month, depending on the speed, provider and usage limits.
In addition to the monthly fee, you might need to pay installation and setup costs, which can range from 4,000 yen to 30,000 yen.
Another challenge for foreigners is language support. Many internet providers in Japan do not offer their service in English or other languages like Tagalog, Bahasa or Vietnamese. In these cases, you may need help from a Japanese-speaking friend or family member during the setup process.

Internet carrier | Type of internet | Speed | Min. contract period | Monthly rate | English support |

Mobile data in Japan
Getting a mobile SIM card for your smartphone in Japan can be more challenging for foreigners. Most network carriers require a credit card and phone number—but you often need one to get the other. This process can be confusing, especially if you’re new to the country.
To help fill this gap, Smiles Connect was launched.
Smiles Connect
Smiles Connect is a foreigner-friendly SIM service from the same company that operates Smiles Mobile Remittance, the “Absolute number one” mobile international money transfer app in Japan. It was developed with empathy and passion to help immigrants stay connected with family and friends—without the usual paperwork or language barriers.
Smiles Connect uses top Japanese network carriers for its SIM service:
- SoftBank for data plans
- NTT Docomo for voice plans
These networks are known for strong, fast and reliable coverage across the country.
How you can save money on data and internet fees in Japan
Smiles Connect offers Combo plans, which include both data and voice SIMs—perfect if you want a Japanese phone number and plenty of data.
One of their most recommended options is the 110GB Combo plan, which includes two SIMs:
- One 100GB SIM for mobile internet data
- One 10GB SIM, which has data and calling/SMS functions
You can use the Data SIM in a pocket Wi-Fi device and bring it anywhere—ideal for those who are always on the go. It also works well as a substitute for home Wi-Fi.
Price: ¥4,980 per month (excluding tax)
With this plan, you get fast, flexible internet access across Japan without long contracts or complicated paperwork. Learn more about the plan here.
