eSIM vs Physical SIM Card: Which to Pick for Japan?
Share
đŻđ” Travelling in Japan: how to stay connected?
Today, staying connected during your trip to Japan is essential: for using Google Maps, translating a menu, booking a train or posting your photos on Instagram.
Two main options are available to you:
-
Buy a local physical SIM card.
-
Use a digital eSIM, like the ones offered by PlanJapan.
So which one should you pick? Here is a clear, no-nonsense comparison.
đČ What exactly is an eSIM?
An eSIM (for embedded SIM) is a virtual SIM card built directly into your smartphone. You activate it by scanning a QR code â no physical card, no plastic, no trip required.
With PlanJapan, you receive your eSIM by email seconds after purchase, and you can activate it on arrival or even before.
âïž Comparison: eSIM vs physical SIM card in Japan
| Criterion | PlanJapan eSIM | Physical SIM card |
|---|---|---|
| đŠ Delivery | By email, instant | At the airport, in store, or delivered |
| đ« Activation on arrival | Yes, within seconds | Yes, but requires insertion and setup |
| đ Immediate connection | Yes, right off the plane | Yes, if installed correctly |
| đ¶ Network | SoftBank or Docomo (the best) | Varies by vendor |
| đ± Dual SIM possible | Yes (keep your home SIM active) | No (usually replaces the main SIM) |
| đ§ł Bulk | None, 100% digital | You handle a plastic card |
| đ Reusable | No, but reactivation possible with a new code | No |
| â Loss or damage risk | None | Yes, lost card = no network |
| đ§ Ease of setup | Super simple (QR code) | More technical depending on the phone |
| đ Security | High (no card to steal or lose) | Less secure |
â Why the eSIM almost always wins
-
Zero stress: no need to hunt for a SIM counter after a 12-hour flight.
-
100% digital: no more plastic, no logistics, no waiting.
-
Activation in 2 minutes: instant and reliable connection with PlanJapan.
-
Flexible: keep your home SIM for bank calls or SMS.
-
Discreet & eco-friendly: less waste, more simplicity.
đ¶ And when it comes to performance?

-
Fast and stable 4G across the country
