Beyond the price tag
Nomad Japan eSIM hotspot 5G and fair-use rules
Price is only half of the decision. The cards below are the terms that decide whether the Nomad pick survives a real trip in Japan.
Hotspot and tethering
AllowedShared with your plan data
Nomad advertises sharing your data across multiple devices rather than a separate tethering allowance, so hotspot traffic comes out of the same plan data.
Speed and 5G
5G available15–300 Mbps
Typical real-world download on the fastest host network, NTT Docomo. Actual speed depends on which mast your phone picks and how busy it is.
Fair-use threshold
2 GB/day on unlimited plans
Drops to 1 Mbps
Every one of the 150 Nomad unlimited plans we track states the same threshold: 2 GB at full speed per day, then unlimited at 1 Mbps. Nomad publishes no brand-wide fair-use figure - its destination pages point you at the individual plan's details, and that is where this number comes from.
Top-ups
AvailableExtra data is sold as an add-on and activates automatically on the existing eSIM when the original plan expires, so there is no new QR code to install.

The masts behind the plan
Which network does Nomad ride in Japan
Nomad owns no towers in Japan. This plan connects to the local host carriers KDDI, NTT Docomo, SoftBank — so coverage, speed and rural reach follow those masts rather than the brand on the voucher.
NTT Docomo
5G25–300 Mbps
Japan's gold standard for coverage — mountain passes, rural islands, basement floors. If your route leaves the cities, prefer a Docomo-based plan.
SoftBank
5G15–250 Mbps
Excellent in cities and on major tourist corridors, with 5G around big stations. Rural reach is good but a step behind Docomo.
KDDI
5G20–250 Mbps
Strong nationwide, with a particularly good grip on western Japan and coastal routes. City speeds rival Docomo.

Price by trip length
What Nomad costs by trip length in Japan
The same trip priced two ways — Nomad's own cheapest plan that stays valid for the whole stay, against the cheapest rival plan covering the same days in Japan.
| Trip length | Nomad cheapest | Cheapest rival in Japan | cheaper |
|---|---|---|---|
| 3 days | $4.00 7 days · 1GB | $1.99 3 days · 1GB · Roami | Roami cheaper |
| 5 days | $4.00 7 days · 1GB | $1.99 7 days · 1GB · Roami | Roami cheaper |
| 7 days | $4.00 7 days · 1GB | $1.99 7 days · 1GB · Roami | Roami cheaper |
| 10 days | $7.00 30 days · 3GB | $3.00 14 days · 3GB · Roamic | Roamic cheaper |
| 15 days | $7.00 30 days · 3GB | $4.00 30 days · 1GB · Ubigi | Ubigi cheaper |
| 30 days | $7.00 30 days · 3GB | $4.00 30 days · 1GB · Ubigi | Ubigi cheaper |
Pick your trip length and this re-reads the plan table above on the spot — the cheapest plan whose validity still covers the whole trip, against the cheapest rival in the same country.

Only plans whose validity covers the whole trip are counted here, so a 30-day trip is priced with a 30-day plan rather than a 5-day one stacked up. Each pick shows its data allowance next to the price — a 500MB trial pack undercuts a 5GB plan for a reason.
One column per brand, cheapest plan that covers the whole trip. Rivals are the other providers we track in Japan.
