October 21, 2023

Rich in culture and history, Japan is one of the most amazing destinations in the world. If you are planning a trip there, you are in for a magical ride. Fascinatingly combining ancient traditions with modern innovation, Japan offers travelers a unique and unforgettable experience. From bustling cities to tranquil rural areas, this country has something for every traveler to enjoy.

Tokyo, the capital city, is a vibrant metropolis that showcases the country’s technological advancements and cutting-edge fashion trends. The city is full of must-see landmarks such as the Tokyo Skytree, which offers breathtaking views of the city, and the bustling Shibuya Crossing, where thousands of pedestrians cross the intersection at once. Travelers can also explore traditional neighborhoods like Asakusa, home to the famous Senso-ji Temple, or experience the vibrant nightlife in areas like Shinjuku and Roppongi.

Another must-visit destination in Japan is Kyoto, known for its rich history, stunning temples, and traditional geisha culture. The entire city is a treasure trove of UNESCO World Heritage Sites, including the stunning Kiyomizu-dera Temple with its magnificent wooden stage overlooking the city, the Arashiyama Bamboo Forest, and the Fushimi Inari Shrine.

For nature lovers, a trip to Hokkaido, Japan’s northernmost island, is an unforgettable experience. Hokkaido is known for its breathtaking landscapes, including the picturesque lavender fields of Furano and the stunning Shiretoko National Park, home to diverse wildlife and pristine lakes. During winter, the area becomes a haven for skiers and snowboarders, with world-class resorts.

If you are looking for a more serene experience, a visit to the historical city of Nara is highly recommended. Nara is famous for its friendly deer that roam freely in the park and its imperial temples, including Todai-ji, which houses the world’s largest Buddha statue. The city’s tranquil atmosphere and beautiful gardens make it a perfect place to unwind.

Japan’s efficient and extensive transportation system, including the renowned bullet train Shinkansen, makes traveling around the country a breeze. Whether you’re exploring the streets of Osaka, bathing in a hot spring in Hakone, or marveling at the floating torii gate of Miyajima, Japan is sure to amaze you!

No trip to Japan would be complete without experiencing its incredible cuisine. From sushi and ramen to tempura and kaiseki, Japanese food offers an unparalleled culinary adventure. Our tip – try everything!

Planning a trip to Japan is so exciting, but don’t forget to consider all the important details. It may not be the most fun part of trip planning, but purchasing a data package plan ahead of time will save you a lot of time, money, and headspace. There are a few different options for data plans in Japan, and in the hopes of making it all a little less confusing, I’ll be explaining each of them to you below. So, let’s get to it!

Can I buy a SIM card in Japan?

Anyone over the age of 18 who lives in Japan or is traveling can buy a Japanese SIM card from SoftBank and various network operators, such as MVNOs – Bmobile, COMST, GTN Mobile, IIJMio, Modal, Nippon SIM Sakura Mobile, Wi-Ho! & Wireless Gate. However, all of these options do come with some restrictions. The main limitation is that short-term visitors cannot buy Japanese SIM cards that support voice calls. 

This means that SIM cards in Japan for short-term visitors are data-only – you can not make or receive calls. 

Japan is relatively strict about SIM card rules, but they are pretty easy to purchase. In Tokyo, international travelers can buy SIM cards directly at the airport, either at Haneda or Narita. Upon arrival to the airport, look out for electronics stores like Yodabashi Camera or BIC Camera to buy your SIM. These stores can be found in many cities around Japan should you decide to purchase your SIM outside of the airport.  

It’s important to note that tou cannot buy the SIM card directly from major Japanese telecom companies such as SoftBank.

So what to do? I’ll explain everything! Plus, I have some calling options for you, too.

Where to Buy a Short-Term Japan SIM Card

You have two options, you can either order a SIM card online before your trip to Japan, or you can buy one once you arrive.

Pre-Order a SIM Card:

You can have your SIM card waiting for you when you land, and pick it up directly from Haneda and Narita airports upon arrival. You will find their booths near the exit; there are usually several local phone providers offering phone services for travelers at international airports in Japan. You should have your passport with you and the sales staff will assist you with the SIM swap process.

You can also find SIM cards at local stores, such as Bic Camera or Yodobashi Camera (pretty much everywhere in Japan), or at a Docomo, AU, or Softbank store.

Long-Term SIM Card Options

For those planning to be in Japan long-term (over 3 months) you will need to get a plan with calls and not just data.

There are two options for long-term SIM cards. One is to sign up with one of the three major network providers – SoftBank, au or Docomo – all of which require purchasing a brand-new phone that is locked to the provider and the SIM card. In addition, these companies also ask for a two-year contract with a high penalty fee should you try to break the contract. This rule is in place to prevent customers from switching to other providers.

A cheaper alternative is to sign up with an MVNO that offers Data + VoSIM cards specifically for those planning to stay in Japan for over three months. Prices can range from ¥2,300 to ¥7,000, as opposed to the regular monthly phone bills of ¥7~11,000 that come with signing up with one of the major carriers.

Which is better, a SIM card or an eSIM for Japan?

If you’re debating between using a physical SIM card that you buy in Japan and an eSIM solution abroad, both options have their advantages and considerations that should be taken into account.

A physical SIM card that you buy in Japan has several advantages. First, it allows you to get instant access to a local number and internet upon arrival, assuming you bought the card at the airport. In addition, physical SIM cards provide the flexibility to choose between different providers and plans according to your specific needs. This allows you to compare prices to choose the best option for you.

On the other hand, eSIM solutions also offer quite a few advantages. With eSIM, there is no need to physically insert or replace SIM cards in your device. Instead, all you need to do is scan the QR code that will be sent to you – and start browsing! From the moment you arrive in Japan, you can make calls and enjoy the internet without breaking your head from dealing with a physical SIM card. Another bonus is that with an eSIM, you get to keep your local number throughout your stay in Japan. Plus, eSIM isn’t just going for Japan. It’s available in 69 countries, so if you’re planning to travel elsewhere, you can easily add these places to your plan.

So how do you choose? Here are some things to consider:

First, not all devices support eSIM, so it is important to make sure your device is compatible. In addition, the availability and support for eSIM may vary between countries and service providers, so it is important to research and confirm that eSIM services are accessible in Japan. In the case of the company eSIMple- it does.

Japan has a well-established communications infrastructure, and major cities and tourist destinations generally have excellent network coverage for both physical SIM cards and eSIM cards. However, if you are planning to travel to remote or rural areas, it is worth making sure that the coverage provided by your communications provider will be valid everywhere in Japan.

And of course, prices are also something to consider. The pricing for physical SIM cards and eSIM solutions may vary depending on the company – but it is always recommended to do a price comparison to determine which option best suits your budget and requirements.

Internet in Japan – All You Need to Know


Most hotels in Japan offer free in-room internet via wireless LAN and/or wired internet via LAN cable. 

Wi-Fi Spots

Wi-Fi is available in Japan in certain areas, but it’s important to note that it will mostly be paid. It will be especially common around train stations, shopping malls, restaurants, cafes, and bars.

Free Wi-Fi Spots

Thanks to the efforts of businesses and the government, free public Wi-Fi networks for foreign tourists are becoming more common. You can find this in international airports, major train stations (including all Yamanote Line stations and many Shinkansen stations), select cafes, fast food stores, and coffee shops.

It’s important to note that most free WIFI spots require a relatively cumbersome registration process.

Final Thoughts

Choosing between a physical SIM card and an eSIM solution for your trip to Japan will depend entirely on your personal preferences, device compatibility, and specific needs. Physical SIM cards offer flexibility in choosing a provider and convenience for those who prefer to handle everything in person, but eSIMs provide quick, hassle-free activation without the need for physical cards, making them a convenient option for eSIM-compatible devices. An eSIM offers flexibility in crossing borders and can be beneficial for those who prefer a digital solution.

If you are looking for reliable eSIM solutions, I recommend eSIMple – with fair pricing, a good selection of packages and countries, and excellent customer service, they’re your best bet for connection services in Japan.
