starts when you first connect here, not when you pay. Install at home. - At the allowance, data stops or continues at a reduced speed, depending on the plan. - Hotspot permission and caps depend on the plan. With no separate cap, tethering uses the plan's data. - On plans that allow top-ups, add data without reinstalling. Each top-up has its own validity. - Data only, unless the plan includes calls or SMS. Internet calling depends on app access and local restrictions. ### Not sure how much data? Start with your recent daily phone use, then add room for train searches, walking directions, translation and photo uploads. Download maps and entertainment over Wi-Fi before long journeys. On an unlimited plan, the row states what unlimited means there, such as a full-speed allowance or a speed cap, and any separate tethering cap. If you fall short, a top-up adds data to the same eSIM on the plans that take one. - 3 GB: Maps, messages, light browsing - 10 GB: Plus social media and photo uploads - 20 GB: Plus streaming and video calls - Unlimited: Heavy daily use. Unlimited terms differ by plan and length: a daily full-speed allowance, one allowance for the whole plan, a speed cap or no cap at all. Check the terms for the length you pick. ### Visiting more than Japan? Regional plans that include Japan, each with its own country list to read against your route. - ![Southeast Asia](https://simfuse.app/og/esim/region-southeast-asia.png) Southeast Asia, 10 countries, from EUR 2.59: https://simfuse.app/esim/region/southeast-asia/ - ![Asia Pacific](https://simfuse.app/og/esim/region-asia-pacific.png) Asia Pacific, 15 countries, from EUR 4.29: https://simfuse.app/esim/region/asia-pacific/ - ![Asia](https://simfuse.app/og/esim/region-asia.png) Asia, 18 countries, from EUR 4.09: https://simfuse.app/esim/region/asia/ - ![Global](https://simfuse.app/og/esim/region-global.png) Global, 193 countries, from EUR 2.69: https://simfuse.app/esim/region/global/ ## More Japan eSIM plans, built your way Pick the network, data and number of days to see the matching plans and prices. Every row shows its own validity, tethering and allowance terms. To build one: call `build-plan` on the MCP server at https://simfuse.app/agentic/mcp with `country_code: "JP"`, the data in MB, the days, and optionally the network and whether calls and texts are bundled. It answers with one real plan and its live price, never a made-up combination. `list-plans` with `destination: "JP"` lists every sellable plan, including the same size on each network. ## How do I check a Japan eSIM's network coverage? Each plan names the carrier it runs on and the generation it supports. The honest limit is the one residents live with too: long tunnels, subway stretches and mountain trails still drop the signal. Save your Shinkansen booking and download walking maps before departure, especially if your trip includes routes such as the Kumano Kodo. | Carrier | Network | Plans | |---|---|---| | KDDI | 5G, 4G/LTE | 36 | | SoftBank | 5G | 14 | | Rakuten | 5G | 11 | - Hotspot / tethering: Allowed on every plan. Any cap is on the plan's row. - At your allowance: On metered plans, data stops - Calls and SMS: No, data only ## Using data in Japan, what to know before you go - **Keep booking details available offline**: Save hotel addresses, train bookings and meeting points before leaving Wi-Fi. A working data plan does not guarantee a connection at every point on your journey. - **Check any phone-number requirement**: If a booking asks for a Japanese phone number or SMS verification, check that requirement before choosing a plan. A data-only eSIM does not supply a Japanese number, and included calling does not by itself establish which country's number you receive. - **Use airport Wi-Fi as a setup backup**: Japan's tourism board confirms free Wi-Fi in major international airport terminals. Keep your installation instructions accessible so you can check them before leaving the airport. ## Best eSIM for Japan, and how SimFuse compares Price per GB on a 10 GB, 30 days Japan plan, checked September 20, 2026.

As fast as the local network is at that spot, which is the same connection residents get. Plans that carry 5G say so on the row, and fall back to 4G where 5G has not reached. Congestion, buildings and your own phone all move it, so no eSIM can promise a number. Each unlimited plan states its own terms on its row, whether that is a daily full-speed allowance, a speed cap or no cap. ### How to get an eSIM for Japan Install it at home over Wi-Fi, on an unlocked phone that supports eSIM. The validity clock does not start until the eSIM first connects to a Japanese network, so setting it up days early costs you nothing. On arrival, select it for mobile data. Narita publishes counter locations and individual opening hours for SIM sales and Wi-Fi rental; check your terminal if that is your backup. Japan's major international airports also provide free terminal Wi-Fi. ### Japan SIM card, pocket Wi-Fi or eSIM: which should you buy? Japan's tourism board lists airport SIM sales and pocket Wi-Fi rental among the alternatives to a travel eSIM. A physical SIM needs an unlocked phone with a suitable SIM slot. Pocket Wi-Fi can suit a group staying together or devices without eSIM support, but adds a router to charge and return under the rental company's terms. An eSIM is installed on your compatible phone. Check its hotspot rules before expecting it to connect a laptop or another traveller's phone. ### Will you pay roaming charges in Japan? Not on the SimFuse plan. You pay once, upfront, and nothing arrives afterwards. Your home SIM bills by its own tariff: if that tariff includes Japan, as Roam Like at Home does for EU and EEA home SIMs inside the EU and EEA (within fair use), it costs what it does at home. If not, it bills at your carrier's roaming rate, so turn off data roaming and automatic data switching before you land. ### Can I make calls and send texts? (Japan-specific) No. The plans listed here are data only, with no call or SMS allowance. You can use calling and messaging apps over data. ### Do I need an eSIM for Japan? (Japan-specific) No. Compare your home carrier's roaming, a local SIM and pocket Wi-Fi with a travel eSIM. Your phone must support the option you choose. An eSIM has no rental router to collect or return. ### How much is an eSIM in Japan? (Japan-specific) Japan eSIM plans from SimFuse start at EUR 3.29. Compare the live plan prices with their data and validity. Charges from your home SIM are separate, so check its roaming settings before travelling. ### How does eSIM work in Japan? (Japan-specific) An eSIM is a digital SIM installed on a compatible, unlocked phone. Follow the selected plan's activation instructions and choose it for mobile data in Japan. On a supported dual-SIM phone, your home line can remain available, subject to its own charges. ### Should I choose an eSIM or pocket Wi-Fi for Japan? (Japan-specific) An eSIM suits a compatible phone without a separate router to carry. Pocket Wi-Fi can suit several devices travelling together or a phone without eSIM support. Compare the total rental cost and return rules with an eSIM's hotspot allowance. ### Will I get a Japanese phone number with the eSIM? (Japan-specific) Only if your selected plan explicitly includes a Japanese number. Data-only plans do not include one. If a plan includes calls or texts, check the number's country and its allowances before relying on it for bookings or SMS verification. ### Can I use my Japan eSIM as a hotspot for a laptop? (Japan-specific) Yes, on plans that allow tethering, and each plan row says which do. If the row shows a separate tethering cap, the laptop is limited to that amount. If not, it draws on the same data your phone does. On an unlimited plan, the row also states what unlimited means there. ### What is the best eSIM for Japan? Japan eSIM plans from SimFuse start at EUR 3.29. Pick on three things: the data you use in a day, how long you stay, and whether you need to tether. Compare validity and allowance terms below. Use Advanced filters to check the available networks. ### Which networks does the Japan eSIM use? Japan plans run on KDDI, SoftBank, and Rakuten. Carriers differ between plans. Use Advanced filters to check available networks. Your phone shows the local carrier's name in its status bar. An unstated generation is not a promise of 4G or 5G. ### Do I need to keep my home SIM while in Japan? Keep it if you want your existing number reachable for calls and texts. On a dual-SIM phone, your home SIM and travel eSIM sit side by side. Calls and SMS included with your travel plan use its own line. Turn off data roaming and automatic data switching on your home line to control its roaming use. ### Is my phone compatible with an eSIM? Check your exact model and regional version in the compatibility guide, then look for 'Add eSIM' in your phone's settings. The phone also has to be carrier-unlocked. Brand and release year are not enough on their own, because some regional versions of an eSIM-capable model ship without it. Check your exact phone model: https://simfuse.app/guides/esim-compatible-phones/ ### What happens when my data runs out? Some plans stop until you top up, others continue at a reduced speed, and each plan row says which. A top-up adds data to the eSIM you already have. Each top-up option states its own validity and says if it replaces your current plan. ### Can I get a refund if it does not work? Yes, within 30 days of purchase, while the eSIM is unused. One that has never connected and has used no data is refunded in full, including when your phone turns out not to support eSIM or you could not get a connection at all. Once it has connected and carried data, contact support and we will look at it. ### Cities in Japan Tokyo, Osaka ### More Asia eSIM destinations - ![Thailand](https://cdn.simfuse.app/46/th.jpg) Thailand, EUR 2.59: https://simfuse.app/esim/thailand/ - ![Indonesia](https://cdn.simfuse.app/23/id.jpg) Indonesia, EUR 2.59: https://simfuse.app/esim/indonesia/ - ![India](https://cdn.simfuse.app/26/in.jpg) India, EUR 2.69: https://simfuse.app/esim/india/ - ![Vietnam](https://cdn.simfuse.app/50/vn.jpg) Vietnam, EUR 2.59: https://simfuse.app/esim/vietnam/ - ![China](https://cdn.simfuse.app/10/cn.jpg) China, EUR 3.39: https://simfuse.app/esim/china/ - ![Singapore](https://cdn.simfuse.app/45/sg.jpg) Singapore, EUR 2.59: https://simfuse.app/esim/singapore/ ## For agents - Send a traveller to this page: https://simfuse.app/esim/japan/ - Structured data: [JSON-LD](https://simfuse.app/esim/japan.jsonld), the page's Schema.org graph including product images and offers.
