Moving to Japan long-term? Here's how to get fast, affordable home internet — fiber plans compared, sign-up steps explained, and what to do while you wait.
A mobile SIM or pocket WiFi works fine for a short trip, but if you're putting down roots in Japan, fixed-line fiber internet (Hikari — 光) is faster, cheaper per month, and far more reliable for remote work and streaming.
1. Best Home Internet Plans in Japan 2026
| Provider | Speed | Monthly Cost | Why It Stands Out |
|---|---|---|---|
| Rakuten Hikari | 1 Gbps | ~$22 | Bundle with Rakuten Mobile for an extra discount |
| NURO Hikari | 2 Gbps | ~$14 (year one) | Fastest speeds at the lowest intro price |
| So-net Hikari | 1 Gbps | ~$29 | Rock-solid reliability, good English support |
| au Hikari | 1 Gbps | ~$37 | Stable and easy to bundle with au mobile |
2. What You'll Need to Sign Up
- A residential lease in your name (or written permission from your landlord)
- Your Residence Card (在留カード) and registered Japanese address
- A Japanese credit or debit card
- A property inside the fiber coverage area — check each provider's website before committing
3. How to Get Set Up
- Run a coverage check on the provider's website, then choose your plan
- Apply online or by phone — some providers offer English-language support
- A technician visits to install the line; book 2–4 weeks out, especially in busy moving seasons (March–April)
- Plug in your router and follow the setup guide — you're live
4. Bridging the Gap: Pocket WiFi
Waiting 2–4 weeks for your fiber line? Rent a Pocket WiFi device (~$13–$20/month) from WiMAX or Docomo to keep you connected in the meantime. Most devices support multiple devices simultaneously, so your laptop, tablet, and phone are all covered.
