Figures, prices and terms were checked against Okiraku Home Wi-Fi official terms on 5 August 2026. They change — check the current terms yourself before you sign up or file anything.

In short

  • Staying 2+ years in one place? Fibre is fastest but needs construction. Want internet this week with no construction? A home router like Rakuten Turbo.
  • The best fit for most foreigners is Okiraku Home Wi-Fi: from 4,400 yen a month, no data cap, and the router is rented free – you never buy it, so there is no leftover debt (as of July 2026).
  • Payment is by credit card only. No card yet? Read how foreigners get a credit card first.
  • Return the router before you leave Japan. If you do not, they charge you 32,780 yen for the router plus 3,300 for the SIM, 4,400 for the AC adapter and 1,650 for the Ethernet cable — 42,130 yen in total.
  • Setup is one step: plug it into an outlet.

Living on your phone’s data alone works for a while. Then, near the end of every month, it doesn’t – your speed drops, video calls with family freeze, and online banking on café Wi-Fi feels unsafe.

This guide explains the three ways to get internet at home in Japan, and why – for most foreign residents – the answer is not the one Japanese people usually choose.

Why fibre is the wrong first choice for most newcomers

Fibre optic internet (光回線 / hikari kaisen) is fast and cheap, and it’s what locals pick. But it comes with friction that hits newcomers hard:

  • 1-2 month wait for an installation appointment – no internet until then
  • 2-year contracts with cancellation fees if you move or leave Japan
  • Installation needs the landlord’s permission – often refused in rentals
  • Removal fees may be charged when you move out

If you move often, don’t know how long you’ll stay, or need internet now, fibre is too heavy. The practical answer is a home router – no installation required.

The three options compared

Comparison: fibre is fastest but needs 1 to 2 months of installation; a home router works the same day with no installation; a pocket Wi-Fi is portable.
Type Monthly (incl. tax) Installation Ready in Speed Portable
Fibre ¥4,000-6,000 Required 1-2 months ◎ fastest No
Home router ¥4,400-4,950 None Same day-days ○ video OK Home use
Pocket Wi-Fi ¥3,000-4,000 None Same day-days ◎ yes
Phone tethering SIM cost only None Now △ depends

Why a rented router beats a bought one

Choose a router you rent, not one you buy. The clearest example is Okiraku Home Wi-Fi. It plugs into a power socket and creates Wi-Fi – no cables, no engineer, no landlord permission – and the router itself is rented to you for free.

Why does renting matter so much? If you buy the device in monthly instalments and then move away or go home, you can be billed for the whole remaining device balance at once. When you only rent it, you simply give it back. For anyone whose time in Japan is uncertain, that difference is the whole decision.

Okiraku Home Wi-Fi at a glance as of July 2026. Monthly from 4,290 yen on the 2-year plan, or 4,620 yen with no contract, plus a 3,300 yen set-up fee. The device is a free rental at 0 yen, and it must be returned when you cancel (official fee schedule, August 2026). It plugs into a socket with no construction.
  • No installation – plug it in and use it the day it arrives; no landlord permission
  • Unlimited data – video and family calls without worrying
  • No contract lock-in – no cancellation fee when you move or leave Japan (important for foreign residents)
  • Device effectively free with the current campaign (check the latest terms on the official site)

Honest caveat: a home router uses wireless signal, so it is less stable than fibre. In weak-signal areas or deep inside buildings it can slow down. If online meetings are your job or you play large online games, waiting for fibre is worth it.

Staying in Japan 2+ years? Tokutoku BB Home Wi-Fi is worth a look too

Okiraku keeps you light by renting the router for free, but you have to return it when you leave. Tokutoku BB Home Wi-Fi pays for the router in installments instead, so once you finish paying it off, the router is yours – no return needed. A better fit if you plan to stay long-term and are not planning to move again soon.

  • No cancellation fee even on the 2-year plan
  • Same as Okiraku on unlimited data and zero installation work
  • Credit card payment only
  • Caveat: the router is paid off in installments. Cancel before it is fully paid and the remaining balance is billed at once. If you might leave Japan within a couple of years, Okiraku (a free rental) is the safer choice

Which one is right for you?

Your situation Best choice
Staying 2+ years, family at home, work from home Fibre (worth the install wait)
Renting, moving often, unsure how long you’ll stay, need it now Home router (rented, not bought)
Want it outside too, living alone, lower usage Pocket Wi-Fi
Barely use internet at home, want to save Phone tethering

If you live alone and use little data, you may not need home internet at all – an unlimited SIM with tethering can be enough. Check your phone plan first.

How to sign up

Four steps: apply online, verify identity, the device arrives by post, plug it in to go live.

You need the same things as a SIM: your residence card, a Japanese address, and a payment method. If you haven’t registered your address yet, do that first – see our guides.

Want something portable? A pocket-type router is another option.

Frequently asked questions

Does it really work with no installation?

Yes. A home router just plugs into a power socket and connects to Wi-Fi. No cabling, no engineer visit – it works the day it arrives.

Can I get one in a rental apartment?

Yes. There is no building work, so you don’t need the landlord’s permission, and there are no removal fees when you leave.

Can I apply with just my residence card?

Yes. Identity is verified with your residence card. Enter your name and address exactly as written on it.

What happens when I leave Japan?

With a no-lock-in plan you can cancel with no penalty. If you paid for the device in instalments, check the remaining balance.

Is phone tethering enough?

If you live alone and use little data, it can be. Rakuten Mobile’s unlimited plan includes unlimited tethering. If you have family or watch a lot of video, a home router or fibre is better.

Summary

  • Staying long, family, home office → fibre
  • Renting, moving often, need it now → home router (Rakuten Turbo)
  • Want it outside, lower usage → pocket Wi-Fi or phone tethering

For most foreign residents, a home router with no installation and no lock-in is the least stressful choice.
