eSIM Japan: FAQ
1Which eSIM do I need for Japan?
Choose a MonoEsim data pack for Japan. For a one-week trip with maps, messengers and social media, 3–5 GB is usually enough.
2How much does mobile data in Japan cost with an eSIM?
An eSIM for Japan starts at €4.90 at MonoEsim. No contract and no hidden roaming fees — you only pay for the pack you choose.
3Does the eSIM work everywhere in Japan?
Stay online in Tokyo, Kyoto and between islands without a local SIM. The eSIM uses local partner networks with 4G and, depending on the area, 5G. In remote areas coverage can be weaker, as with any SIM.
4Do I need roaming in Japan?
No. The MonoEsim eSIM uses a local network. Turn data roaming on for the eSIM line only and off for your regular SIM — so your home carrier charges no roaming fees.
