Overview
For travelers visiting Japan in 2025—especially families, groups, and digital nomads—portable Wi-Fi (often called “pocket Wi-Fi”) remains one of the most reliable ways to stay connected. Unlike SIM cards or eSIMs that work only on a single phone, a rented Wi-Fi router allows you to connect multiple devices simultaneously, including smartphones, laptops, tablets, cameras, and gaming consoles.
Portable Wi-Fi has become increasingly popular among travelers because:
- You can start using it immediately upon arrival.
- It provides stable, high-speed internet almost everywhere in Japan.
- You can share one device with multiple people, making it cost-efficient for groups.
This guide covers the best portable Wi-Fi rental services in Japan in 2025, updated pricing, practical comparisons, and everything you need to decide whether Wi-Fi or SIM is the right option for your trip.

Pocket Wi-Fi vs SIM/eSIM Comparison Table
| Use Case | Best Choice | Why |
|---|---|---|
| Using multiple devices | Portable Wi-Fi | One router supports 5–10 devices |
| Solo traveler | SIM/eSIM | Cheaper and simpler |

Why Portable Wi-Fi Is Worth Renting in Japan
1. Works Immediately Upon Arrival
No need to search for SIM counters, QR codes, or APN settings. If you choose airport pickup, you simply collect the device, press the power button, and connect. If you select hotel delivery, the device will be waiting at check-in.
2. Perfect for Groups and Families
Portable Wi-Fi supports multiple devices—usually up to 5–10 connections at once. For a family of four, one router is often cheaper than four separate SIMs.
3. Ideal for Laptops and Tablets
If you plan to:
- Work remotely
- Upload photos or videos
- Use navigation on multiple devices
- Stream content on a tablet
A pocket Wi-Fi provides more stable, consistent speeds than tethering from a phone.
4. Simple Setup
Most devices require no technical knowledge:
- Turn on the router
- Enter the Wi-Fi password on your devices
- Connect instantly
There is no SIM removal, no settings menu, and no compatibility issues.
5. Easy Return
Most companies provide:
- A prepaid return envelope
- Airport return boxes
- Hotel drop-off options
The return process typically takes less than one minute.
Potential Drawbacks of Pocket Wi-Fi
1. You Must Carry and Charge an Extra Device
Battery lasts around 10–15 hours, but heavy usage (video calls/streaming) can drain it faster. Some travelers may need to carry a power bank.
2. Unlimited Plans Still Have Fair Usage Limits
If you use large amounts of data in a short time (e.g., downloading huge files), your connection may experience temporary slowing.
3. Risk of Loss or Damage
Because the device is rented, companies charge fees for loss or breakage. Optional insurance is usually available for a few dollars per day.
4. Slightly More Expensive for Solo Travelers
If you are alone and only using one phone, SIM/eSIM options are usually cheaper.

Multiple hotels → Airport pickup may be easier
3. Estimate Your Data Usage
Navigation + messaging → 2–3GB/day
Video streaming → 5–10GB/day
Remote work → Unlimited recommended
4. Think About Battery Life
If you spend the entire day sightseeing, choose a model with 12–15 hours of battery, or carry a power bank.
5. Choose the Best Pickup Option
Options include:
- Airport Counter Pickup (fastest)
- Hotel Delivery (most convenient)
- Home Delivery (for residents of Japan)
Step-by-Step: How to Rent Portable Wi-Fi in Japan
Step 1: Book Online
Booking in advance guarantees availability, especially during:
- Cherry blossom season (March–April)
- Golden Week (late April–early May)
- New Year holidays
- Summer vacation (July–August)
Step 2: Choose Data & Duration
Select unlimited or daily data limits based on your travel needs.

Step 5: Return Easily

When SIM/eSIM May Be a Better Option
Choose a SIM or eSIM instead of pocket Wi-Fi if:
- You are traveling alone
- You don’t want to carry extra devices
- You want the cheapest option (eSIMs start as low as $3–$5)
- You only need data for your smartphone
- You are staying one month or longer
For these situations, eSIMs such as Airalo, Holafly, or Japan-specific MVNO plans may offer better value.
When Portable Wi-Fi Is Clearly the Best Choice
Pocket Wi-Fi is ideal if any of these apply to you:
- You’re traveling with family or a group
- You need to connect multiple devices (laptop + phone + tablet)
- You work online while traveling
- You want high-speed internet everywhere
- Your phone is SIM-locked or incompatible
- You prefer a no-tech-setup solution
- You frequently use Google Maps, YouTube, TikTok, or cloud uploads
If reliability and convenience are your priorities, portable Wi-Fi is often the best solution.

With predictable pricing, strong national coverage, long battery life, and simple pickup/return methods, Wi-Fi routers remain a top choice for visitors in 2025.
