Special internet plans for ALT staff with English support from application through installation and setup.
Not sure which internet is right for a one-year stay? We help you choose before you arrive.
Choose Fiber or Plug & Go 5G. Plug & Go is available as a Tower or Dock 5G, both at ¥5,980 per month. Delivery costs vary by device.
Choose Tower 5G for home or portable Dock 5G 01 for Wi-Fi at home and on the go. No NTT fiber installation visit.
A fixed optical-fiber line for the most stable home connection. Best for gaming, work from home, heavy streaming and multiple devices.
If you are waiting for your NTT Fiber installation, choose a temporary Wi-Fi option to use until your Fiber connection is ready.
Our Plug & Go Mobile pocket Wi-Fi loan includes 100 GB per month while you wait for Fiber installation.
Pocket Wi-Fi without a monthly data cap under this temporary plan. Use Plug & Go Mobile while waiting for Fiber installation, subject to coverage.
Plug & Go Mobile is our name for the pocket Wi-Fi range, regardless of the available device model. These temporary options are separate from the ¥5,980/month Plug & Go Tower and Dock 5G home plans. Availability, loan/return conditions and the billing basis for the ¥4,400 option will be confirmed before activation.
For a simpler start without an installation appointment, Plug & Go is often easier. Choose Fiber when connection stability matters more than setup time.
