Landing in Tokyo, Osaka, or Sapporo? An eSIM gives you instant data the moment you connect — no shops, no paperwork.

Coverage snapshot

Strong LTE/5G in Tokyo, Yokohama, Osaka/Kyoto, Fukuoka and major Shinkansen corridors. Rural mountain routes may fall back to LTE — perfectly fine for maps and chat.

Setup in 60 seconds

  • iPhone: Settings → Cellular/Mobile Data → Add eSIM → scan your QR → set as Data line → enable Data Roaming.
  • Android: Settings → Network & Internet → SIMs/eSIM → Add eSIM → scan QR → set as Mobile Data → enable Roaming.
APN usually fills automatically. If asked, use the APN in your order email and leave user/pass blank.

Hotspot & performance

  • Hotspot works on most plans — great for laptops and cameras.
  • If data slows in dense areas, toggle airplane mode for 15 seconds to refresh.

Quick plan picks

  • Short stay (1 week): 3–5GB is plenty for maps, chat, rides.
  • Two weeks: 5–10GB if you stream a bit.
  • One month: 10GB+ or grab a backup eSIM to top up later.

Local tips

  • Download offline maps for your region (good for tunnels).
  • Keep your home SIM active for banking SMS; set eSIM as Data Only.
  • Station Wi-Fi can be crowded; your eSIM is usually faster and safer.

If something isn’t working

  • Ensure the eSIM line is the active Data line and Data Roaming is on.
  • Disable VPN/ad-blockers temporarily.
  • Restart the phone or select a different network manually.
