For those considering a visit to Japan, choosing between Pocket Wi-Fi and SIM Card (eSIM) might be a common dilemma. Let's explore which option might be more suitable.
In a nutshell, here are the key features:
Mobile Wi-Fi: Allows sharing among multiple devices, ideal for traveling with friends or family.
SIM Card (eSIM): Dedicated to individual devices, tailored to personal communication needs.
In Japan, Mobile Wi-Fi primarily utilizes communication from major carriers, ensuring fast speeds and stable connectivity. On the other hand, Prepaid SIM Cards (eSIM), provided by MVNOs, may have slower speeds compared to Mobile Wi-Fi. However, using them with smartphones poses no issues. For activities like online business meetings, opting for Mobile Wi-Fi with faster and stable speeds is advisable.
Offers fast communication speeds and maintains stability even when multiple devices are connected simultaneously.
Speeds may be inferior to Mobile Wi-Fi, but for smartphone usage, it remains problem-free.
Mobile Wi-Fi often provides ample data capacity, with options exceeding 100GB. Prepaid SIM Cards (eSIM), designed with a short-term usage assumption, generally offer smaller data capacities. However, recently, Prepaid SIM Cards (eSIM) with around 50GB capacity have become available.
Suitable for short-term to long-term stays.
Typically designed for a usage period of around 30 days.

When using a smartphone during travel, activities such as web browsing, messaging, and using Google Maps are likely to be the primary focus. In such cases, a communication speed of 3-5 Mbps should be sufficient. However, if your stay involves business-related communication through video or if you want to watch videos, you might need a bit more speed.
For reference, here is a data illustrating the ideal internet speeds needed for various activities.
