Pocket Wi-Fi vs. eSIM for Japan Travel: Which One is Better?

In this guide, we'll help you make an informed choice. Whether you need translation at a charming ryokan or navigate Tokyo's intricate rail system, a reliable internet connection is not just a luxury—it's a must.

Differences Between Pocket Wi-Fi and eSIM

Before your adventure begins, it's important to understand the differences, between both technologies. Pocket Wi-Fi is a small, portable router that wirelessly connects your devices to the internet, normally provided by service provider. On the other hand, an eSIM (or electronic SIM) is embedded within your device and allows you to activate a mobile data plan through the internet.

How to Choose Between a Pocket Wi-Fi and an eSIM

A critical factor in determining your choice is the balance between data need, consumption and the number of travellers. For people travelling in small groups (5 to 10 people) who expect to be online all day, streaming and sharing, pocket Wi-Fi may offer a larger data capacity, at a consistent speed. In contrast, individual travellers opting for brief access and streamlined use can find the eSIM more efficient.

Pocket Wi-Fi is a plug-and-play method. It is often compatible across multiple devices and locations, offering a strong, consistent signal even in rural areas. Yet, eSIMs are baked into your device, alleviating the need to juggle multiple gadgets. They often provide city-wide coverage but can wane in remote pockets.

Pros and Cons of Pocket Wi-Fi

Pocket Wi-Fi is a trusted ally for many travellers, but like any good thing, it has its downsides.

Pros of Using Pocket Wi-Fi

Pocket Wi-Fi grants you internet access across multiple devices so your phone, tablet, and laptop can synchronise seamlessly. Then, sales reports, social updates, and soothing Spotify playlists will function perfectly, whenever you need them.

Cons of Using Pocket Wi-Fi

Mobility comes with a price, and in the case of a pocket Wi-Fi rental, it means an extra item to carry and charge. The pocket-sized routers often need to be recharged daily, adding an extra task to your day-to-day activities.

Pros and Cons of eSIM

On the flip side, eSIMs are certainly the minimalist approach. With their rise in popularity, they streamline the process of staying connected abroad.

Pros of Using an eSIM

They're built-in and hassle-free. The eSIM eliminates the jumble of wires and additional devices, ensuring a lighter travel load, physically and mentally. They are ideal for the modern traveller enjoying digital nomadism.

Cons of Using an eSIM

eSIMs alone are prone to battery drains. Unless your device is unlocked and compatible, activating an eSIM plan may prove a challenge, compelling you to purchase or carry a secondary unlocked device.

Several rental services and telecom providers offer pocket Wi-Fi rentals, or eSIM plans for Japan, each with its own unique selling points.

Free Wi-Fi in Japan

Japan, as a country, is renowned for its safety, and the same extends to its public Wi-Fi networks. Public Wi-Fi networks in Japan are generally secure and encrypted, but it's always wise to exercise caution and connect through VPNs for sensitive data.

Free Wi-Fi can be found in international airports, major railway stations (including all Yamanote Line stations and many shinkansen stations), on select trains and buses, certain coffee spots like Starbucks, fast food and convenience stores, and numerous tourist information offices.

Is it Worth Getting a Japanese Number?

One often-overlooked aspect is the acquisition of a Japanese phone number. Both pocket Wi-Fi and eSIM solutions offer the possibility to obtain a Japanese number, which is great for those needing local business communications, or other such interactions.

While optional, the acquisition of a Japanese number can have its benefits - especially for reservations, local calls, and for receiving notifications or codes that may be needed during your stay.

Shall I Choose Pocket Wi-Fi or an eSIM Then?

In conclusion, the choice between pocket Wi-Fi and eSIM boils down to your personal requirements. Avid social media enthusiasts or users constantly needing multiple devices may find pocket Wi-Fi more beneficial, while minimalist or short-term tourists could lean towards eSIM.

Whatever path you take, a reliable connection is key, to fully experiencing Japan. From feeding deer in Nara Park to marvelling at Akihabara's tech hub, the right connectivity partner helps you have a better travel experience.
