Japan eSIM plan comparison

All 26 Japan eSIM options: fixed data, Unlimited, Essential and Plus

Choose a fixed allowance for a known data budget, or compare the unlimited plan families by trip length. The standard Unlimited family is shown here as Unlimited / Lite to help distinguish it from Essential and Plus; the Shopify product variant itself is named “Unlimited.” Review each product's high-speed allowance, reduced-speed policy and hotspot terms before purchase.

Staying 30 days in Japan? Choose from fixed-data plans of 3GB, 5GB, 10GB, 20GB, 50GB or 100GB, each valid for 30 days. The 1GB fixed plan lasts 7 days and the 2GB plan lasts 15 days. The unlimited plans listed below have shorter validity periods, up to 15 days. Select a plan that covers your entire trip.

Fixed-data packages (8)

Unlimited standard (6)

Unlimited Essential (6)

Unlimited Plus (6)

Prices were read from the AloOui Japan eSIM product in Shopify on 31 October 2026. Prices, promotions and availability may change; the linked product variant is the final source at checkout. “Unlimited” is a plan name and does not by itself promise unlimited full-speed data.

Haneda or Narita: save your arrival route

From Haneda Airport, the Tokyo Monorail reaches Hamamatsucho, while Keikyu services connect toward Shinagawa. From Narita Airport, the Narita Express serves Tokyo and Shinjuku, and the Keisei Skyliner reaches Nippori and Keisei-Ueno. Match your hotel to the arrival station before choosing a service. Download the booking, terminal and final walking route so a tired arrival involves fewer searches.

Rail transfers and four Tokyo neighbourhoods

The JR Yamanote Line links major districts, while Tokyo Metro and Toei Subway fill in the city network. Save the operator, line colour and exit number alongside your destination. Reception can dip in tunnels or deep inside stations, so keep the next interchange visible offline. Check the actual departure platform rather than following another train with a familiar destination name.

• Shibuya: save your restaurant’s building and floor, plus the nearest station exit, before joining the crossing crowds.
• Shinjuku: pin your hotel entrance and chosen exit; the station’s different sides can lead to very different walks.
• Asakusa: download your Senso-ji meeting point and return subway route before browsing Nakamise’s shops.
• Akihabara: keep a shop’s Japanese name and floor number available for electronics shopping and translation.

Tokyo-specific tip: Tokyo Station’s Marunouchi and Yaesu sides face different streets. Save the side named by your hotel or tour operator, especially when meeting a driver.

Planning Kamakura? Download your outbound and return rail options and a walking map before leaving; temple visits are easier with bookings and meeting details already saved.

Which Tokyo itinerary fits your data habits?

Important: These are usage patterns, not measured data-consumption promises. Streaming quality, background syncing and video calls can change your actual usage substantially.

Airport arrival: what to prepare before landing

Five things worth saving offline in Tokyo

1. Hotel address and entrance: save the Japanese address, not only the English hotel name.
2. Station exit: large stations such as Shinjuku and Tokyo can have exits on opposite sides of the complex.
3. Rail itinerary: capture line, operator, transfer station and destination platform, then check live information when connected.
4. Tickets and reservations: keep accessible copies of attraction bookings, train reservations and meeting instructions.
5. Emergency contacts: save accommodation and travel-provider contact details in case mobile service is interrupted.

Keep your regular SIM and travel eSIM organized

On a compatible dual-SIM phone, you may be able to leave your usual line active for calls or account verification while using the travel eSIM for mobile data. Before departure, review which SIM is selected for data, whether automatic data switching is enabled, and what your home carrier charges for roaming. A data-only travel eSIM does not automatically include a Japanese phone number, ordinary voice minutes or SMS.

For messaging apps that use your existing registered number, changing the mobile-data line usually does not require changing the app account. However, receiving a verification SMS on your home number may still depend on your home carrier and roaming settings.

Tokyo eSIM connection troubleshooting

Questions to answer before checkout

Does the selected product cover Japan for the entire trip? Does validity start on installation or first supported-network connection? Is its allowance total or renewed daily? Are there speed reductions after a high-speed threshold? Is hotspot permitted? Are calls and SMS included or is the plan data-only? Check the current Japan eSIM product listing for the exact package terms rather than relying on a general city guide.

Tokyo eSIM: practical arrival and navigation tips

Arriving from the airport

From Haneda or Narita, choose the airport train or bus based on your actual hotel district and arrival time.

For Hakone or Kamakura day trips, check the operator and return connection before setting off.
