Japonya için En İyi eSIM (2026)

Pick a Japan-listed prepaid plan with enough data for cities and bullet-train days. Install the QR on Wi‑Fi before Narita or Haneda landing; confirm your phone is unlocked and eSIM-capable.

Moderate use: 8–12 GB. Heavy maps, translation apps, and social video: 15 GB+ or unlimited fair-use if offered.

eSIM is lighter and shares one device—great for solo travelers. Pocket Wi‑Fi suits groups sharing one hotspot but adds pickup/return logistics.

Yes on open routes; tunnels may dip signal briefly on any network—download offline maps for long rural legs.
