Internet in Japan: Finding a Service Provider in Tokyo

Poste date: Friday, August 7, 2020

One of the many great things about living in Tokyo–being a modern city-is all the modern technological conveniences that come with it, including Internet access. In Japan–as in many other developed countries–there are two primary ways in which you can access the Internet from your apartment; wired or wireless. There are also a few variations in the services available for each category.

Getting a broadband Internet connection in Tokyo

The main thing to understand about broadband Internet access in Japan is that there are actually two separate companies who play a part in providing you access to the Internet. First, there is the company responsible for installing the actual lines to connect your house to their network. The second company is the Internet service provider (ISP), who will be in charge of providing you the actual Internet services.

The company in charge of installing your Internet connection in your home will generally provide one of two main types of broadband Internet access. These types are ADSL and Hikari-Fiber (known as fiber optic in many other countries). A limited number of these companies do still offer a cable connection for those that are interested. While there are some technological differences between ADSL and Hikari-Fiber, they are both able to provide high-speed Internet access at a similar price point. The main distinction between the two connection types is that Hikari-Fiber has a much higher theoretical speed and is able to provide a higher tier of service, usually refered to as a "gigabyte service" or something similar.

Be sure to check with your building's management and the company that is in charge of installing the Internet connection when choosing and Internet connection type as the type of connection you are able to use will vary depending on your address and the building.

Below are the two main companies that provide high-speed Internet line connections.

Flet's

NTT East is the main line provider in Tokyo and offers Hikari Fiber through its FLET’S network in and around Tokyo and all of the Kanto area. Also, the Giga service, which is the latest and fastest version of broadband Internet access, offers download speeds at rates of up to 1 gigabyte per second.

You may need to prepare a wifi router

If you would like to use WiFi, you may need to purchase a wifeless LAN router (Wifi Router) by yourself. They can be easily found on a web shop like Amazon.

Tokyo Internet Service Providers (ISP)

The second part of getting your broadband Internet connection is finding an Internet Service Provider. Some providers can bundle your line connection with the Internet service they provide for added convenience. Check with your ISP about this possibility. Below are the four main ISPs available in Tokyo.

Assist Solutions

Assist Solutions is Japan’s only hybrid ISP, partnered with not just one but two of Japan’s top tier network backbone (IIJ and NTT PC Communications). And unlike many other ISP’s in Japan, Assist Solutions provides English customer support.

Wi-Fi Providers in Tokyo

Another way to access the Internet is by using the cellular networks. With the advent of the 3G and 4G mobile networks, it is now possible to get Internet access for your computer using various devices like 3G wireless modems. These wireless modems give you the ability to connect wirelessly to the Internet–at speeds comparable to wired Internet access–wherever cellular service is available. This is ideal for individuals who are unable to have wired Internet service in their home or apartment, or for those who prefer the flexibility of reliable Internet access wherever they go in Tokyo.

If you don’t want to be tied down to a wired connection (albeit possibly with a WiFi router at your apartment), there are a couple of options for wireless Internet around Tokyo. Your two major options are either portable wireless Internet modems or connected WiFi.

Portable wireless Internet modems connect to one of several wireless data networks and provide Internet access to your computer either via WiFi or an Ethernet cable. Below are five companies that offer this kind of service.

Genki Mobile

Genki Mobile offers affordable portable Wi-Fi routers to visitors in Japan. They provide data usage of 1GB/day using NTT Docomo’s network–one of the most popular service providers in Japan–which provides fast and reliable service in subways and rural areas. They also provide free delivery across Japan, free pick up at the Genki Mobile office, and pick up at select airports.

Asahi Net

AsahiNet, mentioned above as a broadband Internet provider, also provides wireless Internet service via several networks, with its fastest being the WiMax 2+ network. If for some reason this network doesn’t cover your address or needs, they have several other options that cover almost 100% of Japan with wireless Internet access.

AU

au is the cellular service brand of KDDI, a major Japanese telecom that offers wireless Internet access through its “au one net” either by tethering your computing to your mobile phone or via its WiMAX service.

Wi-Fi Hotspots in Tokyo

If the above options aren't for you then you can always rely purely on WiFi hotspots. Around Tokyo, this is often a perfectly viable option. While not ubiquitous, there are free Wi-Fi access points throughout Tokyo, including in most train and subway stations. You can also find them in Starbucks, many convenience stores, and in many public places around the city.

There are also paid WiFi subscription services that will give you much broader access to WiFi access points around the city. Depending on where you live and/or spend your time, this may serve as a convenient and cheaper alternative to having a wired Internet subscription service at your home.

Wi2 300 is one company that provides access to over 200,000 WiFi hotspots across Japan and offers subscriptions in hourly, daily, and weekly segments. Check their site to see if you have sufficient coverage where you live and work.

The biggest caveat to relying only on WiFi hotspots is that you never know when you’ll be out of range of the nearest access point. That said, if 1) you don’t require much in terms of dedicated high-speed access, 2) do most of your Internet browsing on your phone, or 3) your home happens to sit within range of a WiFi hotspot access point, you can have the best of all worlds at a very reasonable price.
