In the case of individual Internet contracts, even inexpensive connection types can cost 3,500円 per month, totaling a loss of about 42,000 円 per year. However, with the installation of our “Free Wi-Fi Apartment” the Internet becomes literally free, with the result that our service has gained notice as a popular equipment choice.

The Internet is available immediately upon move-in.
Because installation and service provider contracts are unnecessary, the Internet can be used on the very day of move-in.

There are large benefits for smartphone and non-PC users too!
Even an economical smartphone can now have a fast Wi-Fi connection of 300 Mbps (802.11n), compared to an LTE connection of only 75 Mbps. In addition to speed, because the Wi-Fi connection is free, it can also lead to data usage savings.
