FYI: What is FLET’S Hikari?

”FLET’S Hikari” is the name of a fiber-optic network provided by NTT, the largest telecommunications company in Japan.

It has the widest coverage compared to other competitors, providing service to over 90% of Japan.

NTT has their network open to other internet service providers. This means that other companies are allowed to use the FLET’S Hikari network and offer internet to customers with their own prices and options.

In other words, SoftBank Hikari borrows the FLET’S Hikari network and supplies it to their own customers.

3. Connection speed and allocated data

The connection speed and allocated data for SoftBank Hikari are as follows:

Connection Speed1Gbps maximum
Allocated dataUnlimited

Aside from SoftBank Hikari, the other companies that use NTT Flet’s Hikari such as docomo Hikari and Sakura Fiber Internet have the same internet connection speeds.

1Gbps is the highest possible speed and will differ from the speeds you actually experience throughout the day. This may cause you to wonder how fast SoftBank Hikari actually is.

“Woah woah! When I was using SoftBank Air, the internet speed was only 10Mbps but I switched to SoftBank Hikari and now it’s 250Mbps 😭 So fast!!”

This individual experienced an internet speed of 250Mbps after switching to SoftBank Hikari. Although this is slower than 1Gbps, it is still more than enough to watch Netflix or play online games.

There are multiple reasons why your internet might be slower than the maximum speed. With NTT FLET’S Hikari, you should expect the speed to be around 100 to 700Mbps.

4. English support

The website for SoftBank Hikari does not have an English version. The application page is also only available in Japanese.

5. The installation process (how long it takes and what you need to do)

After applying for SoftBank Hikari, you will have to talk with an operator to schedule your installation date.

6. Reviews

We have gathered comments about SoftBank Hikari from Twitter. Below, you can see examples of both good and bad customer reviews.

Good reviews

A bargain when paired with the phone discount

“Upload and download speeds are around 600 so I’m super thankful for SoftBank Hikari.
My cellphone bill gets discounted too.”

Fast connection speeds

“My internet speed as of now, 6 pm.
Looking good. I haven’t experienced any connection drops while playing games on the Switch. If the internet is stable even at this time of the day, I think I can safely say my connection problems have been fixed.

It’s been about a week since I replaced my router and I haven’t had any issues.
The BB Unit is most likely the problem for all the SoftBank Hikari users that are having problems playing games.”

Bad reviews

Cannot get a hold of customer support

“Okay, SoftBank Hikari.
I can only cancel my contract over the phone but I can’t even get through to an operator—AND you want me to call at least 7 days beforehand? Literally impossible.
The live chat repeats itself and isn’t much help, either…”

Many add-ons can cause confusion

“The add-ons for SoftBank Hikari are expensive so I was thinking about getting rid of them, but even after looking at the details I don’t understand what any of this means! Make it easier to understand!”
