TL;DR – Best Internet Option If You Don’t Want to Deal with Tech

Note, all pricing information is accurate as of December 2025.

Why Pocket WiFi Is the Best Option If You Want Something Easy

A Pocket WiFi is a small device (about the size of a phone) that creates a secure WiFi hotspot you can connect your phone, tablet, or laptop to, just like your home WiFi.

  • No tech setup required. No apps, no scanning QR codes, no changing settings.
  • No need to remove your SIM card or worry about compatibility or whether your phone is locked.
  • No phone-specific issues. It works with any device that can connect to WiFi.
  • Just one device to manage. Turn it on, connect your phone, and go.

If you’re travelling as a group or family and plan to split up, you can rent multiple devices so everyone stays connected.

You can pick it up at the airport when you land, or have it delivered to your hotel or a Japanese post office. At the end of your trip, drop it in the prepaid return envelope and post it before your flight.

That said, there are a few downsides to be aware of when renting a Pocket Wifi:

  • You must return the device at the end of your trip, either by posting it at the airport or handing it in at a return counter.
  • There are no post boxes after airport security in most terminals. A common mistake is forgetting to post it before going through. If that happens, you’ll need to mail it back from your home country, and cover international postage plus any late return fees.
  • Losing or damaging the unit can result in a high replacement fee (often $200+).
  • Each provider offers optional Device Protection for a small extra fee, which we strongly recommend if you’re concerned about loss or damage.

What’s Included with Your Pocket WiFi Rental

All of our recommended providers offer:

  • Unlimited high-speed data (no daily limits for most plans)
  • Secure WiFi connection for up to 5–15 devices
  • Free or optional backup battery to keep you online all day
  • Airport pickup and hotel delivery options
  • Easy return by mail with a prepaid envelope

You’ll need to recharge the Pocket Wifi unit every night and carry a power bank if you’re out for a full day. Most providers include one, or you can rent one for a small fee.

Top Tip: You can also use the included power bank to recharge your phone!

Why We Don’t Recommend eSims or Sim Cards for Technophobes

Both eSims and physical Sim cards are great, IF you’re confident with settings and setup. But if that’s not your thing, you’ll want to avoid:

  • Scanning QR codes or following multi-step activation instructions
  • Troubleshooting connection issues
  • Changing APN or mobile network settings
  • Removing and reinserting SIM cards (with those tiny tools!)

Pocket WiFi skips all of that. No fiddling, no setup, no stress.

Why Not Just Use Free WiFi?

Japan does have many free WiFi hotspots in stations, cafes, hotels and some public areas, but relying on them has its drawbacks:

Every option we recommend above provides a secure, encrypted internet connection that’s safer and far more convenient than jumping between free WiFi networks.

  • Logging in can be time-consuming at each location.
  • Connections are often slow or unstable.
  • Public and Hotel WiFi is not secure and not suitable for things like banking or bookings.
  • You may not be connected when you need to be, especially when navigating or translating on the go.

Global Roaming: Worth It?

Roaming plans from home providers are usually more expensive, (usually $10-15 USD per day) include less data (often 1GB/day or less) and are slower than local options in Japan. By comparison, Pocket WiFi gives whole groups unlimited high-speed data from $45 USD for 7 days.

For non-tech-savvy people or people with plans that include International Data+Voice access, international day passes from your current provider ARE an easier option to get access to data in Japan.

Usually, you need to log in to your provider account and select the option to activate the international day plan. Many providers automatically activate as soon as you turn your phone on after arriving in a new country, making this also a simple (but more expensive) option. Make sure you check how your provider-specific system works, as well as understand their pricing model, so you have no surprises.

Top Tip: Make sure you do not activate global roaming on your mobile/cell phone without a plan – you can get a major bill shock of thousands of dollars! (I have personally made this mistake once and will never do it again…
