Japan eSIM Prices 2026 — Airalo, Holafly, Nomad & More Compared
Last updated: June 2nd, 2026
Japan eSIM prices in 2026 start at $3.49 for 1 GB and range up to $22.99 for a 20 GB 30-day plan — with Travelsim Asia leading on price across most fixed-data tiers and Nomad consistently within a cent. The headline number doesn't always tell the whole story, though: unlimited plans throttle, validity windows differ wildly, and only one provider connects to all four Japanese networks.

Airalo Japan eSIM prices 2026
Airalo is the most widely recognised eSIM marketplace and a common starting point for Japan travelers. They offer both fixed and unlimited Japan plans, with flexible validity options.
Airalo Japan fixed plans
| Data | Validity | Price (USD) | Price per GB |
|---|---|---|---|
| 1 GB | 3 days | $4.00 | $4.00 |
| 3 GB | 3 days | $7.50 | $2.50 |
| 3 GB | 7 days | $8.00 | $2.67 |
| 5 GB | 7 days | $10.00 | $2.00 |
| 5 GB | 30 days | $11.00 | $2.20 |
| 10 GB | 7 days | $17.00 | $1.70 |
| 10 GB | 30 days | $18.00 | $1.80 |
| 20 GB | 15 days | $24.00 | $1.20 |
| 20 GB | 30 days | $25.00 | $1.25 |
Airalo Japan unlimited plans
| Validity | Price (USD) | FUP (daily high-speed cap) |
|---|---|---|
| 3 days | $11.50 | 3 GB/day → 1 Mbps |
| 5 days | $17.00 | 3 GB/day → 1 Mbps |
| 7 days | $27.00 | 3 GB/day → 1 Mbps |
| 10 days | $35.00 | 3 GB/day → 1 Mbps |
| 15 days | $49.00 | 3 GB/day → 1 Mbps |
| 30 days | $72.00 | 3 GB/day → 1 Mbps |
Networks: SoftBank and KDDI/au. Solid for Tokyo, Osaka, and Kyoto. Thinner in rural Hokkaido and remote areas where docomo coverage matters. App required.
Worth knowing: Airalo raised their Japan unlimited prices significantly in early 2026 — the 7-day plan went from around $15 to $27, and 30-day from ~$35 to $72. At these new prices Airalo's unlimited is no longer the bargain it used to be, and sits close to Holafly and Saily on shorter durations.
Holafly Japan eSIM prices 2026
Holafly only sells unlimited plans — no fixed data options. Their pricing is tiered by duration: roughly $3.90/day on shorter trips, dropping to about $2.50/day on a 30-day plan. Holafly is more expensive than fixed-plan alternatives for typical use, but the longer-duration discount makes them closer to other unlimited providers than the short-trip rate suggests.
| Validity | Price (USD) | Price per day | FUP |
|---|---|---|---|
| 3 days | $11.70 | $3.90 | Not disclosed |
| 5 days | $19.50 | $3.90 | Not disclosed |
| 7 days | $27.30 | $3.90 | Not disclosed |
| 10 days | $36.90 | $3.69 | Not disclosed |
| 15 days | $50.90 | $3.39 | Not disclosed |
| 30 days | $74.90 | $2.50 | Not disclosed |
Worth knowing: Holafly is the most expensive Japan eSIM for short and mid-length trips. A 15-day trip costs $50.90 — versus $16.49 for a 10 GB fixed plan from Travelsim Asia that covers the same period comfortably for most users. The per-day rate drops on longer durations (a 30-day plan works out to about $2.50/day), so Holafly is competitive with Airalo and Saily's unlimited plans at 30 days. On top of that, Holafly doesn't disclose their FUP threshold for Japan, so you don't know exactly how much high-speed data you're getting before throttling kicks in.
Networks: SoftBank and KDDI/au. Good for cities. App optional — can manage via customer panel.
Nomad Japan eSIM prices 2026
Nomad offers competitive fixed plans and some of the best-value unlimited options in the Japan market. They connect to KDDI/au and SoftBank — two of Japan's four major carriers — which gives them reliable urban coverage but less reach in rural areas than four-network providers.
Nomad Japan fixed plans
| Data | Validity | Price (USD) | Price per GB |
|---|---|---|---|
| 1 GB | 7 days | $4.00 | $4.00 |
| 3 GB | 30 days | $7.00 | $2.33 |
| 5 GB | 30 days | $10.00 | $2.00 |
| 10 GB | 30 days | $17.00 | $1.70 |
| 20 GB | 30 days | $23.00 | $1.15 |
| 50 GB | 30 days | $35.00 | $0.70 |
Nomad Japan unlimited plans
| Validity | Price (USD) | FUP |
|---|---|---|
| 3 days | $11.00 | 2 GB/day → reduced speed |
| 7 days | $25.00 | 2 GB/day → reduced speed |
| 14 days | $41.00 | 2 GB/day → reduced speed |
| 21 days | $49.00 | 2 GB/day → reduced speed |
Networks: KDDI/au and SoftBank — two of Japan's four major carriers. App required. Their unlimited plans are the best-value unlimited option in this comparison — significantly cheaper than Holafly for the same trip length, and now also cheaper than Airalo after Airalo's early-2026 price hike.
Saily Japan eSIM prices 2026
Saily is built by the NordVPN team — fixed plans only, no throttling surprises. Pricing sits close to Travelsim Asia and Airalo across the board.
| Data | Validity | Price (USD) | Price per GB |
|---|---|---|---|
| 1 GB | 7 days | $3.99 | $3.99 |
| 3 GB | 30 days | $7.99 | $2.66 |
| 5 GB | 30 days | $10.99 | $2.20 |
| 10 GB | 30 days | $17.99 | $1.80 |
| 20 GB | 30 days | $24.99 | $1.25 |
Networks: SoftBank only — weakest rural coverage of all providers listed here. Fine for major cities. App required. Also offers unlimited plans starting at $18.99 / 5 days with a 5 GB/day soft cap before throttling — honest about the cap, but Nomad's unlimited tiers undercut at most durations.
Ubigi Japan eSIM prices 2026
Ubigi operates as a full MVNO rather than a reseller. Their strength is monthly and subscription-style plans for longer stays.
| Data | Validity | Price (USD) | Price per GB |
|---|---|---|---|
| 1 GB | 3 days | $3.50 | $3.50 |
| 1 GB | 30 days | $4.00 | $4.00 |
| 3 GB | 15 days | $7.50 | $2.50 |
| 5 GB | 15 days | $10.00 | $2.00 |
| 10 GB | 7 days | $14.00 | $1.40 |
| 10 GB | 30 days | $16.50 | $1.65 |
| 25 GB | 30 days | $32.00 | $1.28 |
| 50 GB | 30 days | $55.00 | $1.10 |
Networks: KDDI/au and NTT docomo — strong rural coverage. App required. Their 10 GB / 7-day plan at $14.00 is the best-value short-trip 10 GB option in this comparison. Also offers unlimited plans from $25 / 7 days and an annual plan (60 GB over 12 months) at $59.

The market is tight at fixed-data tiers. On 5 GB and 10 GB 30-day plans, Travelsim Asia leads but Nomad is within a cent at each tier; Airalo and Saily sit roughly $1 above. The real differentiators are network coverage (Travelsim Asia is the only provider in this comparison connecting to all four Japanese carriers — NTT docomo, KDDI/au, SoftBank, and Rakuten Mobile), app requirements (only Travelsim Asia needs no app), and validity on smaller plans.
Which Japan eSIM gives the best value?
There's no single best answer — it depends on your priorities. Here's a straightforward breakdown:
- Best for short trips (1–3 GB): Travelsim Asia — $3.49 / 1 GB / 7 days and $6.99 / 3 GB / 15 days. Nomad's 3 GB / 30-day at $7.00 is essentially tied on price with longer validity. Airalo's 3 GB equivalent is $8.00 for only 7 days.
- Best for standard trips (5–20 GB, 30 days): Travelsim Asia leads on price across all three tiers — $9.99 / 5 GB, $16.49 / 10 GB, $22.99 / 20 GB — and is the only provider in this comparison that connects to all four Japanese networks (NTT docomo, KDDI/au, SoftBank, Rakuten Mobile). Nomad is within a cent on each tier ($10.00 / $17.00 / $23.00) but only covers KDDI/au and SoftBank, and requires an app. Airalo and Saily sit a dollar above. Worth noting: Ubigi's 10 GB / 7-day plan at $14.00 is the best deal in this comparison if you only need 10 GB for a short trip.
- Best for unlimited data: Nomad — $25 for 7 days is the cheapest 7-day unlimited in this comparison, ahead of Holafly's $27.30 and Airalo's $27.00, and Nomad discloses their FUP (2 GB/day) while Holafly doesn't. Airalo's unlimited pricing jumped in early 2026 — 7 days went from ~$15 to $27 — putting it roughly level with Holafly and no longer the budget option it once was.
- Best for extended stays (50 GB+): Nomad's 50 GB / 30 days at $35.00 beats Travelsim Asia's 50 GB / 180 days at $52.99 on absolute price, but Travelsim Asia's plan lasts 6 months — useful if you're making multiple trips to Japan or want headroom for a long stay.
- Best rural coverage: Travelsim Asia is the only provider that connects to all four Japanese carriers, including NTT docomo and Rakuten Mobile. Ubigi is the runner-up with docomo + KDDI/au. Avoid Nomad, Airalo, Holafly, and Saily for rural travel — none connect to NTT docomo, which has the widest coverage outside Japan's major cities.
- Most expensive for short trips: Holafly — at $3.90/day their unlimited pricing is the most expensive option on short trips (a 7-day plan is $27.30), with a non-disclosed FUP. The per-day rate drops on 30-day plans (~$2.50/day, total $74.90), making them competitive with Airalo and Saily at that duration.
Hidden costs to watch out for
The headline price rarely tells the full story. Here are the things that trip people up when choosing a Japan eSIM.
- Throttling on unlimited plans. "Unlimited" means unlimited volume — not unlimited speed. Once you hit the daily cap, speeds drop significantly. Nomad throttles after 2 GB/day, Airalo after 3 GB/day. Holafly doesn't disclose their threshold at all. At throttled speeds, Google Maps and translation apps can struggle. A fixed plan with full speed is often the better experience for most travelers.
- Validity mismatch. Always check the validity window alongside the price. Airalo's 1 GB plan lasts only 3 days at $4.00 — fine for a stopover, poor value for a week-long trip. Travelsim Asia's equivalent is $3.49 for 7 days.
- App requirements. Most providers require downloading an app and creating an account. If you're buying last-minute at the airport with no data, this creates a catch-22. Travelsim Asia delivers by email — no app, no account, installs in any browser.
- Single-network risk. Saily connects only to SoftBank. If you're venturing outside major cities, a multi-network eSIM automatically switches to the strongest available signal. For Hokkaido, the Japanese Alps, or rural travel, this matters.
Unlimited vs fixed: which is actually better for Japan?
Japan is one of the destinations where this question genuinely matters — because you use your phone constantly. Translation apps, train navigation, finding restaurants, messaging. It adds up.
| Fixed data plan | Unlimited plan | |
|---|---|---|
| Speed | Full speed, all the time | Full speed until daily cap, then throttled |
| Predictability | Know exactly what you're getting | Depends on daily usage patterns |
| Price | Lower for typical users | Higher — you pay for peace of mind |
| Best for | Most travelers | Heavy streamers, hotspot users |
| Runs out? | Yes — but you can top up | No — but may throttle badly |
For most Japan travelers, a fixed 5 GB plan is the sweet spot. It covers a week of maps, translation, and social media, costs less than unlimited, and delivers full speed the entire time. If you're a heavy user or hotspotting a laptop daily, consider 10–20 GB fixed rather than unlimited — you get more usable high-speed data for the same or lower cost.
How much data do you actually need for Japan?
Japan is data-hungry compared to other Asian destinations. You'll use translation apps constantly, run Google Maps or Navitime for train navigation, and look up restaurants in a city where English menus aren't always available.
| Usage type | Per day | 7 days | 14 days | Recommended plan |
|---|---|---|---|---|
| Maps, translation, messaging | 300–700 MB | 2–5 GB | 4–10 GB | 3–5 GB |
| + social media and photos | 1–1.5 GB | 7–10 GB | 14–20 GB | 10 GB |
| + video calls and streaming | 2–4 GB | 14–28 GB | 28–56 GB | 20–50 GB |
Most travelers fall in the first or second row. Hotel and café WiFi can supplement your data for heavier tasks.
