Japan eSIM Prices 2026 — Airalo, Holafly, Nomad & More Compared



Last updated: April 23rd, 2026

Japan eSIM prices in 2026 start at $3.99 for 1 GB and range up to $25 for a 20 GB 30-day plan — with Travelsim Asia, Airalo, Nomad, and Saily all competitive in the $10–$18 range for most trips. The headline number doesn't always tell the whole story, though: unlimited plans throttle, validity windows differ wildly, and some providers connect to one Japanese network while others cover all four.

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 $11.40 3 GB/day → 1 Mbps
5 days $19.50 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 $74.00 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 $74. At these new prices Airalo's unlimited is no longer the bargain it used to be, and sits close to Holafly on shorter durations.

Holafly Japan eSIM prices 2026

Holafly only sells unlimited plans — no fixed data options. Their pricing is per day at $3.90/day, which makes them significantly more expensive than fixed-plan alternatives for most trip lengths.

Validity Price (USD) Price per day FUP
5 days $19.50 $3.90 Not disclosed
7 days $27.30 $3.90 Not disclosed
10 days $39.00 $3.90 Not disclosed
15 days $58.50 $3.90 Not disclosed
30 days $117.00 $3.90 Not disclosed

Worth knowing: At $3.90/day, Holafly is by far the most expensive Japan eSIM option in this comparison. A 15-day trip costs $58.50 — versus $16.99 for a 10 GB fixed plan from Travelsim Asia that covers the same period comfortably for most users. 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 also connect to all four Japanese networks — a meaningful advantage over most competitors.

Nomad Japan fixed plans

Data Validity Price (USD) Price per GB
1 GB 7 days $4.00 $4.00
3 GB 30 days $7.50 $2.50
5 GB 30 days $10.00 $2.00
10 GB 30 days $17.00 $1.70
20 GB 45 days $24.00 $1.20
50 GB 45 days $39.00 $0.78

Nomad Japan unlimited plans

Validity Price (USD) FUP
3 days $11.00 2 GB/day → reduced speed
7 days $23.00 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 from $48.99 — poor value compared to Nomad's unlimited options.

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 tighter than it looks. On 5 GB and 10 GB 30-day plans, Travelsim Asia, Airalo, Nomad, and Saily are all within $1 of each other. 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 — cheapest 3 GB plan at $6.99 with 15 days validity. Airalo's equivalent is $8.00 for only 7 days.
  • Best for standard trips (5–20 GB, 30 days): Nomad edges it slightly on price ($10.00 vs $10.99 for 5 GB), but Travelsim Asia is the only provider in this comparison that connects to all four Japanese networks (NTT docomo, KDDI/au, SoftBank, Rakuten Mobile) — Nomad only covers KDDI/au and SoftBank — and doesn't require an app. Airalo and Saily are within cents. Worth noting: Ubigi's 10 GB / 7-day plan at $14.00 is the best deal in this comparison if you need 10 GB for a short trip.
  • Best for unlimited data: Nomad — $23 for 7 days is significantly cheaper than Holafly's $27.30 and Airalo's $27.00 for the same period, 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 / 45 days at $39.00 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.
  • 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.
  • Worst value: Holafly — at $3.90/day their unlimited pricing is by far the most expensive option in this comparison, with a non-disclosed FUP to boot.

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 — fine for a stopover, poor value for a week-long trip. Travelsim Asia's equivalent lasts 7 days for the same price.
  • 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.

🏆 Is Airalo the cheapest Japan eSIM?

Not always. On 5 GB and 10 GB 30-day plans, Airalo, Travelsim Asia, Nomad, and Saily are all within a dollar of each other. Nomad is slightly cheaper on 5 GB ($10.00 vs $11.00). On small plans, Travelsim Asia offers longer validity for similar pricing. The cheapest option depends on the plan size you need.

🌐 Which Japan eSIM has the best network coverage?

Travelsim Asia and Nomad both connect to all four major Japanese networks — NTT docomo, KDDI/au, SoftBank, and Rakuten Mobile. Most other providers connect to two. NTT docomo has the widest rural coverage, which matters if you're visiting Hokkaido, the Japanese Alps, or Okinawa's smaller islands.

⚡ Do Japan eSIMs throttle speed?

Only unlimited plans throttle. Fixed data plans deliver full speed for the entire allowance. Nomad throttles after 2 GB/day, Airalo after 3 GB/day. Holafly doesn't disclose their threshold. For guaranteed full speed throughout your trip, choose a fixed plan.

📱 Do I need an app to use a Japan eSIM?

It depends on the provider. Airalo, Nomad, Saily, and Ubigi all require an app. Travelsim Asia delivers your eSIM by email and manages everything through a web portal — no app, no account needed. Holafly has an optional app but can be managed through a customer panel.

🔄 Can I top up if I run out of data?

Yes, with most providers. Travelsim Asia lets you top up via a web portal with no login. Airalo top-ups through the app. Nomad top-up availability varies by plan. Unlimited plan users can't top up for speed — you stay throttled until the daily reset.

📡 How much data do I need for a week in Japan?

Most travelers use 500 MB to 1.5 GB per day in Japan — more than other Asian destinations due to translation apps, train navigation, and Maps. A 5 GB plan covers a full week for average use. Heavy users or anyone hotspotting a laptop should budget 10 GB for a week.
