Best eSIMs in Japan for international tourists

Staying connected while traveling in Japan is essential, whether you need maps for navigation, translation apps for communication, or instant access to travel tips. Here are some top eSIM options for tourists visiting Japan.

Airalo

Airalo is a global eSIM provider that offers some of the most affordable eSIM plans with broad coverage across Japan. Its activation is quick and easy, making it a great choice for travelers on a budget. However, since it provides data-only services, you won’t get a local phone number for calls.

Ubigi

Ubigi provides fast speeds at competitive prices and works across multiple countries, making it a solid choice for travelers visiting Japan as part of a larger trip.

Nomad

Nomad is known for its high-speed internet and flexible plans, catering to travelers who require reliable connectivity. Its customer service is well-rated, making it easier to troubleshoot any issues. However, some of its plans can be on the expensive side. If you prioritize quality and speed over cost, Nomad is a strong contender.

Holafly

Holafly stands out by offering unlimited data plans, so you never have to worry about running out of internet. There’s no need to top up, which makes it a hassle-free option. However, the convenience comes at a price, as Holafly’s plans tend to be more expensive than competitors. It’s best suited for travelers who stream frequently or need constant internet access.

Japan Wireless

Designed specifically for Japan, Japan Wireless provides excellent coverage and dependable service.

eSIM vs. Pocket WiFi: Is a portable hotspot the better choice?

Whenever you plan a trip, everyone has advice on staying connected abroad—“Get a local SIM, chase free WiFi, or pay for pricey roaming.” Though, if you’ve heard about “Pocket WiFi,” you might be wondering if it’s the smarter choice over an eSIM. Let’s dive in and explore what Pocket WiFi is and why so many travelers swear by it for a seamless internet experience.

What is Pocket WiFi?

Pocket WiFi is a portable, battery-powered wireless router that provides internet access on the go. It works by connecting to a local mobile network and creating a private WiFi hotspot, allowing multiple devices (like smartphones, tablets, and laptops) to connect simultaneously.

Pocket WiFi is popular among travelers in Japan as it offers unlimited data plans and stable connections, making it a great alternative to SIM cards or eSIMs. However, it requires charging, must be carried around, and often comes with rental fees and return requirements.

Why do people prefer Pocket WiFi?

People prefer Pocket WiFi because it offers unlimited data, allows multiple devices to connect, and provides a stable internet connection. It’s ideal for groups, business travelers, and those who need reliable access for streaming, navigation, or work. Thus, unlike eSIMs, Pocket WiFi works with all devices, regardless of SIM compatibility.
