If you're moving to Tokyo or another part of Japan, you'll want to set up a Japanese mobile phone number as soon as possible, preferably before you arrive. You'll need a Japanese phone number to open a bank account, sign a lease, and sort out pretty much everything else that goes with adulting here -- including food delivery and gig tickets. Note: This article is about monthly cellphone contracts. Looking for a prepaid alternative for travel? Check out our guides to prepaid SIM cards (the physical ones) and eSIMs. The basics The easiest way to get a Japanese phone number is to order a SIM card online -- which you can do from abroad and in English, too. Two providers we have used and recommend are Mobal, who donate all of their profits to charity, and Sakura Mobile. They both offer voice-and-data plans, as well as data-only plans. They both also have portable wifi plans, which can come in handy if you’re waiting to have your home Wi-Fi connected. Important: If you're looking for a real Japanese mobile number, get a voice-and-data SIM. If you get data-only, you won't be able to make or receive any calls except via VoIP services (e.g., WhatsApp or LINE). And it might not be accepted when you need to put a Japanese phone number down on documents. Though it may work out cheaper to set up a Japanese phone number through an MVNO or a cellphone store once you're here in the country, it generally takes a lot more time. It can also be a more complicated process and require some fluency in Japanese. So we recommend going the online route, at least initially. You can always switch to a different provider later. Pro tip: Find out how to port (keep) your number when switching, in our guide to long-term cellphone contracts in Japan. How to get a Japanese phone number before you move to Japan If you're going to be working in Japan, your employer might assist with the set-up of a Japanese mobile number. However, if you need to take care of it yourself, ordering a SIM online before arriving is quick and simple. Looking for a job in Japan’s creative industries?

Getting a Japanese cellphone number online Here are two of our main recommendations: Mobal One of the easiest and most popular options is a voice-and-data SIM from Mobal. The order process is straightforward, and they have great English support. You can have your SIM card shipped to you (for free) worldwide or pick up from a range of locations across Japan (major airports and city centers), so you’ll be connected pretty much as soon as you land. You’ll just need to complete the set-up process once you arrive. Here's what you need to know about Mobal plans: Your Japanese cellphone number will use the SoftBank network (one of Japan's biggest). You can make and receive calls, send and receive texts, and, of course, use data. Note: if you want 5G, it's currently available on Mobal's 5G eSIM line (which runs on the au network), not the standard voice-and-data SIM described here. So select that on the product page. Fast data is fixed at 1GB, 5GB, 10GB, or 30GB per month. You’ll never be without data -- speeds will just slow down (to around 200kbps) after your monthly cap has been reached. All plans are available as either physical SIM cards or eSIMs. Monthly fees range from to . Domestic call rates are per minute. Incoming calls are free. There’s a once-off SIM fee of . Unlike some of the major providers, there are no complex contracts, and you can change your plan on a monthly basis. You also have the option to suspend your plan temporarily if you're heading overseas OR they have a roaming option if you still need access to your Japanese phone number. Billing options include debit card, credit card, and PayPal, as well as convenience-store payment. You will need a credit card to complete the initial order online. They also offer a minimalist Voice Lite plan that gives you a phone number and a budget-friendly amount of data in case you just need the phone number for identity verification or contract applications.

Sakura Mobile Another well-known name in the Japanese mobile game, Sakura Mobile offers a range of voice-and-data plans which use physical SIMs or eSIMs. Here's what they look like: Your calls, texts, and data will run on the Docomo network, Japan’s largest. Seven voice-and-data plans are available, ranging from 5GB to 100GB per month. The entry-level 5GB plan goes for per month. On the other end of the scale, the 100GB plan costs per month. Domestic call rates are per minute. The sign-up process is simple, and their contract activation fee is a one-off payment of . Payments can be made by credit card, debit card, or in cash at the convenience store. You can cancel your contract for free at any time after the first month, and you can change your plan monthly. Full English-language support is available. Read more about Sakura Mobile plans. How to get a Japanese phone number after moving to Japan If you decide to wait until after you've arrived in Japan to sort out your mobile number, you can still order one online, or you can go into a cellphone store and set it up there. Getting a Japanese mobile phone number online Simply follow the steps above and get that SIM downloaded or delivered. Again, we recommend this option, as it's the least stressful of the two. Getting a Japanese phone number at a store Walking around outside big train stations (think Shinjuku, Tokyo, Ikebukuro, Shinagawa, and the like) or through shopping areas will take you past a number of different cellphone stores. The big names in the mobile game here are SoftBank, Docomo, au by KDDI, and Rakuten. If you're considering a major provider, it's worth noting that because Rakuten are a bit newer to the game and their networks aren't yet quite as established as the other guys, their plans are currently a fair bit cheaper. Check out our long-term phone plans comparison. You can apply for a contract with them directly in store, though it's worth noting that not all stores will have an English-speaking staff member, and that both the requirements and contracts can be complex. For example, you might be signed up for a minimum of 12 months. Contracts used to be a lot longer (think 24-36 months), with hefty cancellation fees, but times have changed, and regulations have relaxed a bit. These days, a one-month minimum commitment is more common than a 12-month one. However, fiddly add-ons like anti-viruses and mail services are sometimes automatically bundled in the contract, and need to be removed. What is actually most complicated is that you may need to show proof of a Japanese bank account, employment contract, and your visa to qualify for a Japanese cellphone number. Note: Even if you apply for a contract through one of the Japanese MVNOs that piggyback on the big mobile players, like IIJMio or Nuro Mobile, you will likely have to jump through the same hoops. It's recommended you set aside at least half a day for cell number set-up, and ask a fluent Japanese speaker to accompany you if you're not super skilled in the local lingo.

Can I get a temporary Japanese phone number, or one just for verification? If you only need a number for ID checks, app sign-ups, or contract applications -- rather than a full data plan -- the cheapest route to a real Japanese number (070/080/090) is Mobal's Voice Lite plan, at a month. You can order and submit your ID online before you travel, but the number activates to coincide with your arrival in Japan. In other words, it's for people heading to (or already in) the country -- there's no way to get a working Japanese number while you're still overseas. It's also worth steering clear of “virtual” Japanese numbers from VoIP apps like Google Voice: they aren't real Japanese mobile numbers, and they tend to get rejected by banks, government services, and apps that require SMS verification. For anything official, you'll want a proper SIM-based number. Will my overseas phone work with a Japanese SIM card? Yes, as long as it’s unlocked. If you’ve got an existing phone contract and you’re unsure, check with your current provider. Another way to check is by following these instructions for Apple and Android phones. How do I get a new cellphone in Japan? If you're in the market for something new, electronics stores like Bic Camera or Yodobashi Camera are easy to find all over the country. Here, you can purchase a phone outright or sign up for a plan, but the latter will usually require an existing phone number and Japanese language skills. Similarly, Apple stores can usually be found in popular shopping areas like Shibuya, Omotesandō, and Shinjuku, as can big-name cellular stores like SoftBank, Docomo, or au.
