There are many Hikari Internet (optical line) providers in Japan, so foreigners who are not good at Japanese may have trouble deciding which one to choose. In this article, we will introduce 5 Hikari Internet sites in Japan that are recommended for foreigners.

Difference between line carrier and provider (ISP)

When researching Hikari Internet in Japan, there are two types of companies: "line carriers" and "providers." To use Hikari Internet in Japan, you need to know the difference between these two.

What is a line carrier?

A line carrier is a company that provides internet lines such as fiber optic lines. Please note that they only provide the line and do not provide connection services. Japan's main line carriers include NTT, au, and Softbank.

What is a provider (ISP)?

A provider is a company that connects us to the Internet using a network operator's Internet line. It is said that there are several hundred providers in Japan, and each one has different service content such as fees and communication speeds.

In Japan, it is necessary to contract with both the line carrier and the provider.

In Japan, you cannot connect to the Internet even if you contract with only one carrier, so you need to contract with both providers. However, in most cases, contracts between line carriers and providers are made as a set, so there are few cases where you have to go to the trouble of applying to two companies separately.
