Hidden Problems with Pocket WiFi in Japan That No One Talks About

Renting a Pocket WiFi in Japan sounds like the perfect solution for staying connected while traveling. It’s portable, provides fast internet, and works with multiple devices. But many travelers only discover hidden issues after they’ve picked up their device. In this guide, we’ll expose some common Japan WiFi rental issues that most people don’t talk about—and, more importantly, how to avoid them.

Hidden Fees and Unexpected Costs

Data Limits and Speed Restrictions

Many Pocket WiFi rental services advertise “unlimited data,” but there’s often a catch. Some companies implement a fair usage policy, meaning if you exceed a certain amount—sometimes just 3GB per day—your internet speed could be throttled to painfully slow levels. This can be frustrating when you’re relying on fast internet for navigation, streaming, or work.

💡 How to avoid this: Check the fine print before renting and choose a provider with true unlimited data or high daily limits.

Late Return Fees

Let’s say your flight gets delayed, or you forget to return your Pocket WiFi on time. Unfortunately, many rental companies charge high late return fees, which can add up quickly, turning your budget-friendly WiFi rental into an unexpectedly expensive experience.

💡 How to avoid this: Opt for a provider that offers flexible return options or has multiple return locations.

Damage Fees

Accidents happen—maybe your device gets dropped, lost, or damaged. Without insurance, the replacement cost can be shockingly high, sometimes over ¥20,000.

💡 How to avoid this: Consider rental providers that offer affordable insurance plans to cover accidental damage.

Airport Pickup vs. Hotel Delivery: What They Don’t Tell You

Long Queues and Stock Issues at Airports

Picking up a Pocket WiFi at the airport seems convenient—until you realize that everyone else is doing the same thing. Long lines at rental counters are common, and worse, some providers run out of stock, leaving you without a device.

💡 How to avoid this: Pre-book your device online to guarantee availability and consider delivery options.

Hotel Delivery: Pros and Cons

Having your Pocket WiFi delivered to your hotel is a stress-free option—you simply pick it up at the front desk when you check in. However, there are a couple of things to watch out for. If you’re not familiar with Japanese addresses, you might accidentally enter incorrect delivery details, which could result in a failed delivery. Plus, if you’re relying on the device for navigation from the airport to your hotel, you’ll have to manage without internet on the way.

💡 How to avoid this: Pre-book your device, and provide correct information.

Battery Life Issues with Certain Models

Some Devices Don’t Last All Day

Many Pocket WiFi models claim to last a full day, but in reality, heavy usage can drain the battery in just 4–6 hours. That means you’ll either need to find a place to recharge or carry a power bank with you.

💡 How to avoid this: Choose a provider that offers longer battery life models or rent an extra power bank.

Weak Signal in Rural Areas: Is Your Pocket WiFi Reliable?

Connectivity Issues in the Countryside

While Pocket WiFi works great in big cities like Tokyo and Osaka, but rural areas, mountains, and remote islands may have weaker coverage. If your trip includes countryside destinations, like Hokkaido’s national parks or the Japanese Alps, signal reliability becomes a major concern.

💡 How to avoid this: Choose a provider that operates on Japan’s top-tier networks (like docomo) for better nationwide coverage.

Conclusion

While renting a Pocket WiFi in Japan is one of the best ways to stay connected, it’s important to be aware of potential issues before you book. Hidden fees, airport delays, battery life, and rural coverage are all factors that can impact your experience. The good news?
