eSIM plans for Japan

Why do you need an eSIM for Japan?

Japan is one of the most sought-after destinations in the world, but it's also a place where running out of internet can be expensive. The country is not part of the European Union, so your European plan's free roaming doesn't apply, and carriers charge exorbitant rates per megabyte when you're away from home. A travel eSIM solves the problem at its root: you have your data pre-purchased, at a fixed price, and you connect to the Japanese network as soon as you land at Narita, Haneda, or Kansai.

Without an eSIM, your options in Japan are three, and none are convenient: paying your carrier's roaming fees, waiting in line to buy a local SIM at the airport—which involves forms and sometimes your passport—or renting a pocket WiFi, another device to carry, return, and not lose. An eSIM helps you avoid all three: it installs itself on your phone with a QR code and you're all set.

How much does roaming cost in Japan?

It depends on your carrier, but roaming rates in Japan for European and Latin American customers usually range between €15 and €25 per day, or they charge for data at prices that can skyrocket your bill without warning. For a 10 to 14-day trip, that can easily add up to €150 to €350 just for internet. With an eSIM, you pay a fraction of that for the entire trip, and you know the exact price before you leave home.

How many GB do I need for Japan?

Most travelers buy more data than they use. For normal use in Japan—Google Maps for the Tokyo subway, translator for menus, messaging, social media, and uploading photos—1 GB for every 3-4 days is usually sufficient. If you plan to use a lot of maps, video, or share your connection via hotspot, adjust your calculation accordingly. This table can serve as a guide:

What is the best eSIM for Japan?

The best eSIM for Japan is one that combines four things: it connects to the country's top-tier networks (NTT Docomo and SoftBank), provides real 4G/5G in cities, includes hotspot for data sharing, and allows you to keep your usual number and WhatsApp. PuraSIM's eSIM meets all four and adds something that international apps don't usually provide: 24/7 support in Spanish, in case any questions arise mid-trip.

• Local network coverage: you browse at the same speed as a local, not as a roaming guest.
• Activation in 1 minute: receive the QR by email and install it before leaving home.
• Hotspot included: share the connection with your laptop, tablet, or travel companion.
• No permanence or surprises: fixed price and a refund guarantee if you don't end up traveling.

Coverage in Japan: city by city

You'll have signal in all major cities and on the most frequented tourist routes:

• Tokyo: full coverage in the city center, Shibuya, Shinjuku, and Asakusa, and almost the entire subway network, even underground.
• Kyoto and Osaka: stable signal in temples, markets, and on the train between both cities.
• Hiroshima, Fukuoka, Sapporo, and Nagoya: solid coverage throughout the urban area.
• Shinkansen (bullet train): connection for almost the entire journey, ideal for working or sharing the trip.
• Mount Fuji and Hokkaido: good signal on tourist routes and in towns; in high mountains or very remote areas, it depends on the local network, just like with any Japanese SIM.

eSIM, local SIM, or pocket WiFi: what to choose?

The eSIM wins for most trips: you buy and activate it online in minutes, it doesn't take up your SIM tray (you keep your number), you can't lose it, and nothing needs to be returned. A physical local SIM might be worthwhile for very long stays, but it involves queues, paperwork, and swapping out your usual SIM. A pocket WiFi supports multiple devices, but it's a battery-powered device that you have to pick up, charge daily, and return on time. For a normal tourist trip, the eSIM is the fastest and most seamless option.

How do you activate the eSIM for Japan?

In four steps and without technical knowledge:

• 1. Purchase your eSIM plan for Japan and receive the QR by email in less than 1 minute.
• 2. Install the eSIM from home, using WiFi, by scanning the QR in your phone's settings.
• 3. Activate data for that line upon landing in Japan.
• 4. Connect: high-speed internet without any further adjustments.

Data consumption doesn't start until you activate the line at your destination, so you can have everything ready days before you fly.

Tips for not overspending on data

• Deactivate data roaming on your primary SIM so it doesn't consume data by accident; use the eSIM only for browsing.
• Take advantage of hotel and cafe WiFi for large downloads.
• Download offline maps for your area on Google Maps before you leave.
• Keep your usual SIM inserted to continue receiving calls and SMS on your number (Dual SIM mode).

Are you traveling to other countries in Asia?

If Japan is just one stop on a longer trip, a regional or global plan might be more cost-effective than an eSIM per country. Check out the eSIM for Asia, which covers several countries with a single plan, or our eSIMs for ChinaThailand if they are your next destinations. For round-the-world trips or multi-continental itineraries, global plans provide worldwide coverage without changing eSIMs. And if you're still deciding, in popular destinations you'll find the most purchased eSIMs.
