Japan eSIM vs. Pocket WiFi: Which is Best for Digital Nomads & Long-Term Stays?
To anyone considering the "Japan Digital Nomad Visa" or planning a stay in Japan for several months: you are likely wondering about the best way to secure a reliable internet connection.
Many travel blogs and YouTube videos recommend eSIMs as the easiest and best option. To be fair, for a short sightseeing trip of about a week, an eSIM is indeed a great choice.
However, if you are coming to Japan to "Work" or planning to stay for "30 days or more," choosing an eSIM could be a significant risk.
Why do long-term professionals deliberately choose "Pocket WiFi"? In this article, we’ll explain the reality of Japan's telecommunications landscape and compare the best options to ensure digital nomads don't lose productivity.
The "30-Day Wall": Why eSIMs Aren't Built for Long Stays
The first problem digital nomads face is a mismatch in duration. We call this "The 30-Day Wall."
Most eSIMs are Designed for "Tourists"
The majority of travel eSIM plans on the market are limited to 7, 15, or at most 30 days. This is because they are designed to match the length of stay for the average tourist in Japan.
The "Renewal Trap" for Long-Term Residents
If you are staying on a Digital Nomad Visa (6 months) or a 90-day tourist visa, using a 30-day eSIM plan creates the following issues:
- Required Monthly Repurchasing: If you stay for 6 months, you must repurchase a plan at least six separate times.
- Setup Hassle: Every time you renew, you have to install a new eSIM profile or go through the activation process again.
- Reversed Costs: In most cases, the cost of repeating short-term 30-day plans ends up being more expensive than a Pocket WiFi rental with a long-term discount.

Stability & Performance: Can You Rely on eSIM for Work?
Are you planning to join video conferences like Zoom or Google Meet while in Japan? If so, relying on your smartphone's "Tethering" (Hotspot) function is risky.
Hidden Risks of Tethering (Hotspots)
- Heavy Battery Drain: Tethering drains your phone's battery rapidly. When working on the go, you’ll constantly need to worry about finding a charger.
- Throttling Due to Overheating: Smartphones can become extremely hot while tethering. To protect the device, its internal systems may force the connection speed to drop significantly.
- Disconnection from Incoming Calls: Depending on the carrier, receiving a phone call can cause your tethering connection to momentarily drop.
Pocket WiFi is a "Dedicated Communication Router"
Pocket WiFi is a device specifically engineered for communication. It remains stable even when connecting multiple devices like PCs and tablets, and you don't have to worry about your smartphone's battery life. Furthermore, our Pocket WiFi uses the powerful networks of Japan's major carriers and features a high-capacity design built for business use. The communication quality is significantly superior when compared to standard eSIMs or SIM cards.
