Staying connected while traveling in Japan is essential for navigating, staying in touch, and sharing your experiences. While international roaming can be expensive, there are two convenient alternatives: Pocket WiFi (Portable WiFi Router) rental and eSIM.
In this guide, we’ll compare both options, highlight why Ninja WiFi is an excellent choice, and introduce our special collaboration with Hire Taxi Japan for a stress-free, connected journey.
What is a Pocket WiFi?
A pocket WiFi is a small, portable device that creates a personal WiFi hotspot, allowing multiple devices to connect simultaneously. It provides a secure and stable internet connection anywhere in Japan.
Top Reasons to Choose Pocket WiFi:
Perfect for families & groups – Connect multiple devices (smartphones, tablets, laptops) with one rental.
No SIM card swap needed – Keep your home SIM active for calls and texts.
Reliable and fast – Enjoy 4G LTE speeds without worrying about slow or unstable connections.
Great for business travelers – Secure internet access for laptops and work needs.
Useful for getting around – Use Maps, GPS, translation apps, and travel guides without limits.
Should You Rent a Pocket WiFi (Portable WiFi Router)or Get an eSIM?
Both pocket WiFi and eSIMs offer reliable internet access in Japan, but they suit different travel needs.

How Much Data Do You Need for Your Trip?
When choosing between pocket WiFi and eSIM, understanding your data usage is essential. Japan has extensive free WiFi spots, but for reliable and uninterrupted connectivity, a rental device with a sufficient data plan is the best option.

For social media users & occasional streaming: 3-5GB per day is recommended.
For heavy users (video calls, streaming, work files): 5GB+ per day is ideal.
