Why Your First Month in Japan Requires a Different Approach

You’ve shipped your life across the Pacific. You land at Narita or Haneda with a work visa, an apartment lease starting next week, and a to-do list that assumes you’ll have internet. Except getting a Japanese mobile contract requires a residence card (which takes 2-4 weeks after registration), a Japanese bank account (which requires proof of address), and often a year-long commitment. That circular dependency leaves most expats scrambling in their first weeks.

This is the gap we see constantly at ConnectPls: engineers relocating for Toyota, teachers starting JET Programme positions, corporate transfers to Tokyo offices — all arriving with no way to get reliable internet until the bureaucracy clears. You need connectivity that works the day you land, covers your laptop for remote work check-ins and your phone for maps, and doesn’t lock you into contracts before you even know which neighbourhood you’ll settle in.

“We managed to stay always connected while travelling around Europe, without having to buy SIM cards in every country and ending up with a handful of them with different balances we couldn’t use. Excellent support team.”

The Four Internet Options Expats Actually Use in Japan

Why Portable WiFi Makes Sense for Month One

Portable WiFi (pocket WiFi in Japan) connects your laptop, phone, and tablet at the same time. That’s critical when you’re flat-hunting on your computer, messaging landlords on your phone, and video-calling your relocation agency on your tablet. Unlike travel eSIMs that throttle tethering or limit hotspot use, a dedicated mobile router handles proper work-from-home bandwidth.

The catch with traditional pocket WiFi rentals in Japan: tourist-oriented shops at the airport charge ¥800–1,200 per day (£160–240/month). That’s fine for a two-week holiday but painful for the six weeks it takes to get your residence card, open a bank account, and arrange a local contract.

How Monthly Subscriptions Work Differently Than Rentals

ConnectPls is a subscription service, not a per-day rental. The device itself (a portable WiFi router that connects up to 10 devices) is included in your monthly plan and shipped to you before you leave for Japan. For expats, that means you can have it delivered to your UK, EU, or US address (2-3 working days in Europe, 4-5 in the UK) and activate it the day you board your flight.

Japan is in our “Group 1” country tier: you get 4G unlimited data that may slow after about 5GB in a day. For context, that’s roughly 6 hours of Zoom calls or a full work day of remote development. The router uses Cloud SIM technology, automatically connecting across multiple Japanese operators (typically Softbank or NTT Docomo), plus a backup physical SIM slot if you want to add a local SIM later.

The practical difference: billing is monthly and flexible. Use it for your first two months while sorting paperwork, pause it once your local contract starts, reactivate it when you travel to Seoul or Taipei for long weekends. No year-long contract, no hardware purchase, no early termination fees beyond a £25 return-shipping charge if you cancel a mobile-router subscription within the first three months.

What to Actually Expect in Your First Six Weeks

Here’s the timeline we see with corporate relocations and JET arrivals:

Week 1: Land in Tokyo or Osaka. Register your address at the ward office. Start apartment viewings. Your portable WiFi works in cafes, on trains (yes, the Shinkansen), and in your temporary Airbnb. You’re running work calls, uploading documents for your residence card application, and researching neighbourhoods.

Weeks 2-4: Residence card issued. Open a Japan Post Bank account (easiest for foreigners). Start comparing local mobile carriers. Rakuten Mobile if you want English support and no credit check, or the big three (Docomo, au, Softbank) if your employer is covering it. Your pocket WiFi is still your primary connection because most apartments don’t include internet, and home broadband installation takes 2-4 weeks.

Weeks 5-6: Local SIM or home broadband installed. Now you have a choice: cancel the portable WiFi subscription entirely, or keep it active for the flexibility. Many expats we support keep it running at a low tier for business trips around Asia (Japan to Singapore, Tokyo to Bangkok, Osaka to Taipei) because it works across 160+ countries without per-trip setup.

The Van Lifer and Extended Travel Angle

Japan isn’t just a relocation destination. Expats based in Tokyo often spend months road-tripping Europe during summer breaks, or van-lifing between teaching contracts. This is where monthly portable WiFi subscriptions show their value beyond “moving to Japan” scenarios.

Our Plus Europe package is truly unlimited (no fair-usage throttling) across about 70 Group 0 countries: UK, Ireland, France, Germany, Spain, Italy, Portugal, Netherlands, the Nordics, Turkey, plus Canada, Mexico, Australia, and New Zealand. If you’re doing a campervan loop through France and Spain between contracts, or working remotely from a motorhome while exploring Portugal, the same device that got you through your first month in Kyoto now provides motorhome broadband across Europe without separate rentals or SIM swaps.

Compare that to renting pocket WiFi separately for each country, which is what travelers searching “cheapest pocket WiFi Australia” or “cheapest WiFi in France” are trying to solve. A subscription model means you’re not paying daily rates or dealing with return logistics in multiple countries. Activate for the months you travel, pause when you’re stationary.

When a Local Japanese SIM Actually Makes More Sense

Once you have a residence card and bank account, local Japanese mobile contracts are excellent value. Rakuten Mobile offers unlimited data for ¥3,278/month (~£17) with no commitment. IIJmio and Mineo provide eSIM options starting around ¥850/month (~£4.50) for 2GB if you’re mostly on home WiFi.

Local SIMs win on price for long-term residents. But they don’t help you in weeks 1-4, they don’t cover your laptop without tethering (which drains your phone battery on work calls), and they don’t travel with you when you leave Japan. That’s the honest trade-off: if you’re settling permanently in Tokyo and never leaving, a local SIM plus home broadband is cheaper. If you’re on a 1-2 year contract, travel regionally, or work remotely across time zones, the flexibility of a portable WiFi subscription justifies the cost difference.

Setting Up Before You Fly

Order the device to your current address at least a week before departure. Charge it fully (battery lasts 10-12 hours of active use). Activate your plan the day you fly. It works the moment you land at Narita. Slip it in your jacket pocket or day bag. Connect your phone and laptop. You’re online before you clear customs.

That immediate connectivity matters more than you’d think. Immigration sometimes asks to see your hotel confirmation or employer’s address, and you can pull it up on your phone. The Narita Express ticket machines have English interfaces but Google Maps helps you confirm which platform. Your new employer messaged a correction to tomorrow’s onboarding location. You’re not hunting for airport WiFi or buying a prepaid tourist SIM that doesn’t cover your laptop.

Frequently Asked Questions

Can I use portable WiFi in Japan for video calls and remote work?

Yes. 4G unlimited in Japan (Group 1 tier) handles Zoom, Teams, and Slack without issues. Speeds may slow after about 5GB in a day, which is roughly six hours of video calls. For typical remote work (a few hours of calls, Slack, email, web research), you won’t hit that threshold. If you’re uploading large design files or streaming 4K all day, you might notice slowdown in the evening, but it’s still usable for email and browsing.

Do I need to return the device if I cancel after three months?

Yes, the mobile router itself is included in your subscription, so it belongs to ConnectPls. When you cancel, you return it (we provide a prepaid return label). There’s a £25 fee if you cancel within the first three months to cover shipping and return logistics. After three months, cancel anytime with no fee. Many expats keep the subscription active at a low tier even after getting local internet, because it’s useful for regional travel.

What happens if I travel to Korea or Thailand while based in Japan?

The same device works in 160+ countries without changing SIMs or settings. South Korea and Thailand are both Group 1 countries (same as Japan): 4G unlimited, may slow after ~5GB/day. Singapore, Hong Kong, Taiwan are the same tier. If you’re doing weekend trips to Seoul or month-long breaks in Chiang Mai between contracts, you don’t need separate rentals or local SIMs for each country. The Cloud SIM switches operators automatically when you cross borders.
