Japan is easy to travel and easier still with data: train times change platform by platform, restaurants take app bookings, and translation tools earn their keep. A Weettah eSIM connects the moment you land at Haneda, Narita or Kansai.

Coverage

Which networks you'll use in Japan

Your eSIM connects to leading Japanese networks including NTT Docomo, au (KDDI) and SoftBank. Coverage is excellent nationwide, including on the shinkansen, in subways and across most rural prefectures.

Local tips worth knowing

  • Get an IC transit card on your phone where supported — it works on most trains and convenience stores.
  • Cash is still useful at small restaurants and shrines.
  • Rubbish bins are rare in public; carry your litter until you find one.
