Unlimited eSIM Japan – 3 GB/Day on NTT docomo
Share
Japan is Shibuya crossing live-streams at rush hour, group video calls from a Kyoto ryokan, and still having data when you’re halfway up Mount Fuji at sunrise.
Ugoroam Unlimited Japan gives you exactly that.
Why This Plan Wins Japan
- One eSIM, entire country Tokyo → Osaka → Hokkaido → Okinawa → Mount Fuji trails — same plan everywhere.
- Connected the second you land Activate on the plane. NTT docomo signal hits before you reach baggage claim at Narita, Haneda, or Kansai.
- 3 GB fresh high-speed every day New 3 GB resets at midnight Japan time — shoot 4K cherry-blossom footage, stream Spotify on the Shinkansen, live like at home.
- After 3 GB → unlimited 128 kbps Maps, LINE, WhatsApp voice/video, Uber — everything essential keeps working 24/7.
- Truly unlimited hotspot One phone powers the entire JR Pass group, the onsen hotel, the snow-monkey park van, the Tokyo Airbnb — no limits.
