AU HIKARI is a discount service for AU smartphone users and can be used at home at a low price. However, there is a lot of information and types of contract methods, and we often hear that first time users have trouble knowing what type of service they should subscribe to.

In this article, we will introduce the details of the AU HIKARI subscription. We also give you a summary of our special offers.

AU HIKARI Subscription

What is AU HIKARI?


au HIKARI is an internet service provided by KDDI. Depending on the type of residence and the connection method of the optical LAN, there are two main types, “au HIKARI Home” and “au HIKARI Mansion”, with different prices. KDDI’s au HIKARI uses this line to provide internet, telephone and TV services. KDDI’s au HIKARI offers three types of internet service, telephone service and TV service using this line, as well as a super high speed internet service with speeds of up to 10Gbps in limited areas.

Price plan analysis


One of the features of au HIKARI is that the provider fee is included in the monthly usage fee. When you sign an Internet subscription in Japan, you need to sign a contract with two companies: the company that provides the line and the provider. Most people think that having multiple contracts complicates the price, but au HIKARI allows you to make a contract and pay for it all at once, so the total price is low.
※However, au HIKARI allows you to make a contract and pay for it all at once, so the total cost is cheaper. Recently, other line providers have also started to simplify their internet contracts by combining them. The price depends on the type of residence, so I’ll use both types as examples.

Detached type plans
Name of Plans Monthly fee Term of contract / Penalties
zutto Giga Toku 1st year \5,100
2ns year \5,000
3rd year \4,900
3years/\15,000
Giga Toku 5,200Yen Two years/\9,500
Normal Plan \6,300 None/None

※Provider fees are included, so even if you calculate only the basic fee, it is cheaper than FLET’S Hikari.
(FLET’S Hikari Giga Family Smart Type: ¥5,700/month + separate provider fee)

Attention au smartphone users!


With au HIKARI, you can apply au Smart Value (cell phone discount), which provides a discount of up to ¥1,000/month depending on the amount of data communication you have contracted. If your family also uses the same au service, the discount will be applied to a maximum of 10 devices at the same time, making it a great deal! Specific information on discounts based on data volume is as below.

AU Smart Value Details
Discount PLans Discounted mobile phone rates
Pittatto Plan use less than 1GB/month Not eligible for discount
Pitatto Plan use more than 1GB/month ¥500 off
Unlimited MAX ¥1,000 off

Remember that the more family members who use the same carrier, the more benefits you can receive from au Smart Value. Finally, let’s check about the speed of au HIKARI.

au HIKARI’s communication speed is inferior to other companies’ optical fiber lines.


Like FLET’S Hikari and most optical communication line businesses, au HIKARI boasts ulpload and download speed of 1Gbps. Not only that, but the line is reputed to be less crowded, making it ideal for those who want to use the internet at a low cost. In addition, au HIKARI won the top prize in many areas at the RBB SPEED AWARD, organized by RBB TODAY, one of the largest news sites in Japan that provides information related to telecommunications in Japan.

*Note that NURO Hikari’s current transmission speed of 2Gbps is overwhelmingly fast, so it has been excluded from the comparison. If you are mainly interested in speed, please refer to NURO Hikari information.
