1. Essential eSIM for Your Tokyo Trip

Planning a trip to Tokyo, Japan, in 2026? One of the first questions on every traveler's mind is, 'How will I stay connected?' With so many options like traditional roaming, physical SIM cards, and the newer eSIM, it's easy to feel overwhelmed. As someone who visits Japan at least twice a year, I can tell you my go-to choice is always an eSIM.

Why eSIM? It's significantly more affordable than traditional roaming, and the setup is incredibly simple! Today, I'm excited to share my long-term experience using Klook's eSIM in Tokyo, along with essential tips and how to snag a discount when you book.

2. eSIM vs. Physical SIM: Which is Better?

Many travelers find themselves debating between an **eSIM** and a traditional **physical SIM card**. Both options are far more budget-friendly than international roaming, so the cost difference between them isn't usually the deciding factor.

Here's the lowdown: A **physical SIM card** requires you to swap out your existing chip, which can be a hassle for some. Plus, you'll need to keep your original SIM safe to avoid losing it, which is always a risk when you're on the go.

On the other hand, an **eSIM** is incredibly convenient. You simply scan a QR code to download and activate it. Think of it as having two SIMs in one phone – your home network and your travel network – without the need for any physical changes.

The main drawback? eSIMs are primarily compatible with newer smartphone models. For iPhones, you'll need an XS or newer, while Samsung Galaxy users will typically require an S23 or higher-tier model to take advantage of this technology.

3. How Much Data Do You Really Need for Your eSIM?

A common dilemma for Japan-bound travelers is deciding on the right data capacity. In the past, I typically used about 2-3GB per day for navigating with maps and checking social media, relying on Wi-Fi at my accommodation.

However, with the increasing risks of public Wi-Fi — including reports of phone hacking incidents — I now opt for the peace of mind that comes with **unlimited data**. Choosing an unlimited 5G plan ensures you'll experience speeds comparable to what you're used to at home, so you won't have to deal with frustratingly slow connections during your adventures!
