5 Great Japanese Internet Service Providers



Among utilities today, the internet is nearly as important as your water or electricity service, especially with more and more people working from home. When moving house it’s bound to be right near the top of the list of things you really want to make sure are set up properly and functioning before you move into your new place.

But which internet service provider is the best for you? In this article, we’ll talk about how to get set up with internet service in Japan and introduce you to the top five leading internet service providers here.

Setting Up Internet Service in Japan

In this section, we will briefly explain how to get your internet service at home up and running. We will also give you some essential points to consider before you sign up with an Internet Service Provider (ISP).

Wired vs. Wireless

In Japan, there are two types of internet connections available to consumers: wired (fixed connection) and wireless. 

Wired connections are installed in your house or apartment and provide high speeds and high capacity. These can be based on fiber optic cable (光ファイバー in Japanese), come via your television cable service (broadband), or wireless. Wireless connections come in the form of portable Wi-Fi devices. These are convenient as they can be taken outside. This is a good option for those staying less than one year in Japan. However, speeds can be slower than wired and data limits may apply.

How to Set Up Internet in Japan

When you sign up for internet service in Japan, you will sign a contract with two companies: a telecommunications carrier and a service provider. The telecommunications carrier is the network operator who provides all the cables and installations necessary for the internet connection.

Your ISP enables internet connection and service via the fiber optic cables provided by the above telecommunications carrier. In Japan, you will need to make two separate contracts with each company. However, subscription packages that bundle both the broadband line and ISP have become available.

With that in mind let’s move on to the steps to sign up for internet in Japan:

  1. Choose an ISP: we will give you our top five picks for ISPs in Japan below. Research each provider and how they might benefit you, then pick the one best suited for your needs.
  2. Sign up on their website: Once you’ve picked an ISP you must apply for a new contract on the ISP’s official website. Enter the required info such as your name and address, as well as if you live in a house or apartment.
  3. Wait and get connected: It may be necessary for the network operator to visit your home and install the cables needed for the internet connection. If a previous tenant had already had a fiber optic line installed you can use it right away and could save you some money. You may also have to wait two weeks to one month for the installation. 
  4. Enjoy your speedy Japanese internet! Once everything is signed and connected then you will be able to sit back and enjoy your high-speed internet connection.
