Who This Helps
This page is for foreign residents, students and remote workers who need reliable apartment internet in Japan. It does not provide housing-contract, legal, visa, tax, medical or financial advice.
1. Check the apartment first
Do not order fiber or buy routers until you know whether your room has a LAN port, fiber outlet or building internet.
2. Match speed to real use
Video calls, remote work and gaming need stability. Light browsing and messaging may work with simpler mobile backup.
3. Avoid duplicate gear
Some providers include equipment. A LAN cable may solve more than buying an expensive router too early.
The 10-Minute Home Internet Checklist
- Ask whether the apartment already includes internet.
- Check for a LAN port, fiber outlet or provider equipment.
- Ask the landlord or building manager before installation work.
- Decide whether you need a temporary eSIM or Pocket WiFi bridge.
- Compare fiber, Home WiFi and Pocket WiFi separately.
- Confirm contract period, cancellation rules and equipment return rules.
- Wait to buy a router until provider equipment is clear.
- Use LAN for work, gaming or video calls when possible.
- Keep provider login and return information in one note.
- Upgrade only the weak point after one week of real use.

Setup Gear Worth Checking
LAN Cable
A wired connection can improve stability for work calls, gaming and desktop setups.
Wi-Fi Router
Buy only after confirming what your provider includes and what your room layout needs.
Power Backup
A small charger or power bank helps during moving days, setup visits and mobile backup use.
FAQ
Should I order fiber before moving in?
Usually no. First confirm building permission, existing outlets and whether installation work is allowed.
Can Pocket WiFi replace home internet?
It can work temporarily or for lighter use. Heavy work and video calls often benefit from a more stable home connection.
Do I need to buy a router?
Not always. Some providers include equipment. Check the provider setup before buying your own router.
What should I do during the first week?
Use eSIM, SIM or Pocket WiFi as a bridge, then choose a long-term home setup after checking the apartment.
Start With the Room, Then Choose the Provider
The right internet option depends on the apartment, installation rules and your actual work or study needs.
