How to Get Mobile Data in Japan (eSIM & SIM Guide)

📶 Mobile Data : What You Need to Know

When you’re traveling in Japan, having good internet and a place to sleep you can count on is key.

Mobile Data in Japan: What are your options ?

Japan has great mobile coverage, even in rural areas. Here’s how you can stay connected:

SIM Cards

You’ll find prepaid SIM cards at airports and stores like Bic Camera or Yodobashi Camera. These are usually data-only and work for 7, 14 or 30 days. Just make sure your phone is unlocked.

Want to save time? You can also order your SIM card in advance so it’s ready when you land.

eSIMs (the easy way)

If your phone supports eSIMs, this is the smoothest option. No need to deal with tiny plastic cards. You just download the plan and go.

Top picks for Japan:
• You have : Ubigi , Holafly (5% disocunt with my code TABIMAWARI), or Airalo, Saily, Yesim.

You can activate most of them right before or just after landing.

Why Use an eSIM in Japan?

eSIMs are ideal for modern travelers. Here’s why:

✔️ Instant activation
✔️ No need to swap SIMs
✔️ Often cheaper than regular SIM cards
✔️ You stay connected even while switching countries

Plus, if your original SIM has your WhatsApp tied to it, you won’t need to remove it.

Why Mobile Data Changes Everything

Having internet while traveling in Japan is a game changer. Here's what you can do easily:

• Use Google Maps or Navitime to navigate trains and buses
• Check out restaurants, museums, and events nearby
• Translate signs and menus in real time
• Book hotels or Airbnb on the go
• Message hosts, confirm check-ins, or even buy your train tickets

Hi, I’m Marie.

French islander from Reunion island, Japan lover, and travel planner behind Tabimawari.

I spent a year living in Kyoto, learning Japanese and falling in love with the culture. Since then, I’ve kept going back, exploring every corner from Tokyo to the tiniest hidden towns.

I created these guides after spending months planning, testing, and fine-tuning every detail so you don’t have to. Inside, you’ll find:

✅ Interactive maps
✅ Step-by-step directions
✅ Local spots + travel tips
✅ Offline use

Each guide is made with care, based on real-life travel, not generic blog advice.

This is what I wish I had on my first trip to Japan and now it’s yours.
