Heading to Japan for snow season / peak travel / business? BambooSIM just launched Japan 5G Unlimited eSIM plans with full-speed 5G hotspot included — no more 1GB/2GB/3GB daily caps that many “unlimited” providers sneak in.
This is a local Japan eSIM (not roaming) — your data breaks out in Japan, which can mean significantly better speeds and lower latency compared to roaming eSIMs.
✅ Key benefits
- Unlimited data on the KDDI (au) 5G network with coverage across Japan
- Hotspot included at full speed (5G): N days = (N − 1) GB hotspot
- Local Japan eSIM (not roaming) → data breakout in Japan
- FREE Wi-Fi on:
- selected Ferries
- 100+ Mountain Huts
- 100,000+ Wi-Fi Spots across Japan
- FREE Gift redeemable at Lawson outlets (subject to store availability, limited time)
