Best eSIM for Japan Travel 2025: Airalo vs Holafly vs Sakura Mobile
"Do I need a Pocket Wi-Fi in Japan?"
The short answer is: No. In 2025, eSIMs are cheaper, faster, and you don't have to
carry a heavy router around.
⚠️ Don't Buy SIM Cards at the Airport!
SIM cards sold at Narita/Haneda airport vending machines are 2x to 3x more expensive than online prices. They are "tourist traps".
The smart move: Buy an eSIM before your flight takes off. Activate it when you land.
