Compare and buy your Japan eSIM 2026 at the best price

Planning a trip to Japan? eSIM is now the most convenient and cost-effective solution to stay connected abroad. No more long queues at airport SIM counters, surprise roaming charges that can reach hundreds of euros, or lost SIM cards. With an eSIM, you're connected as soon as you land — sometimes even before takeoff.

Our Japan eSIM comparison tool analyzes 1000 plans from 14 verified providers in real-time. Prices start at just €0.00 for basic plans, up to unlimited offers for heavy data users. Among our recommendations: Airalo for its massive catalog (200+ destinations), Saily for enhanced security (created by NordVPN), and Holafly for truly unlimited data plans with no throttling.

Why choose an eSIM for Japan?

• Significant savings: eSIM plans cost on average 70-90% less than traditional roaming from your carrier
• Instant activation: receive your QR code by email and scan it in your phone settings in less than 5 minutes
• Dual SIM: keep your home number active to receive important calls and texts while using eSIM for data
• No physical handling: no more risk of losing or damaging a micro-SIM

How to choose the right plan?

The choice depends on your usage. For a short stay (3-7 days) with light usage (GPS, emails, messaging), a 1-3 GB plan is usually sufficient. For a longer stay or if you plan to stream content, consider 5-10 GB or unlimited plans. Digital nomads working remotely should look for unlimited plans with hotspot/tethering included.
