This site introduces products through an affiliate program.

There are many providers of Hikari Internet (fiber optic line) in Japan, so foreigners who are not good at Japanese may have a hard time knowing which one to choose. In this article, we will introduce five recommended Japanese Hikari Internet providers for foreigners.

Difference between a line operator and a provider (ISP)

When researching Hikari Internet in Japan, you will find two types of providers: "line operators" and "providers". To use Hikari Internet in Japan, you need to know the difference between these two.

What is a line operator?

A line operator is a company that provides an Internet connection, such as an optical fiber line. It is important to note that they only provide lines and do not provide connection services. Major line operators in Japan include NTT, au, and Softbank.

What is a provider (ISP)?

A provider is a company that connects us to the Internet using an Internet connection from a line operator so that we can use the Internet. It is said that there are hundreds of providers in Japan, and each of them offers different services such as fees and transmission speed.

In Japan, you need to sign up for both a line operator and a provider.

In Japan, you cannot connect to the Internet by signing a contract only with a line provider, so you need to sign a contract with both providers. However, in most cases, the contract with the line provider and the provider are made as a set, so there are few cases where you have to go to the two providers separately to apply for the service, which can be troublesome.
