Japan has become a popular destination with international travelers: a record-breaking 42.7 million travelers from abroad visited in 2025. It’s one of the most special places I’ve visited, and I’ll definitely go back.
While planning for their first Japan adventure, people often underestimate how important it is to prepare themselves digitally. Most of us will rely on our smartphones to navigate cities, translate Japanese text, and find restaurants. You need to make sure you have the right tools, tech, and settings for a smooth trip.
Device Security
QR codes are everywhere in Japan. They’re incredibly convenient, but they can also be tampered with or replaced with malicious versions that redirect you to fake websites designed to steal your information. The same goes for downloading apps or files on the go. When you’re in an unfamiliar environment and eager to access something quickly, it’s easy to skip the caution you’d normally exercise at home.
Set up reliable security on your smartphone before you travel to Japan. A trusted app will help you stay safe while you’re roaming, especially if it’s more proactive than reactive.
A proactive security app, like NordVPN next-gen antivirus, runs in the background to protect you 24/7. You’ll get warnings about scam websites, and files infected with malware will be removed.
Pocket Wi-Fi or SIM Card
A pocket Wi-Fi is a small router that you can carry with you wherever you go in Japan. Pocket Wi-Fi units connect to cellular networks (for example, 5G), giving you your own personal hotspot. You can link your smartphone, laptop, or other devices to it instead of joining a public network. A pocket Wi-Fi is especially useful if you’re traveling as a couple or a family, since one unit can keep several devices online at once.
You can book a rental pocket Wi-Fi before your trip. Alternatively, you may buy a tourist SIM card exclusively for use in Japan. SIM cards connect to popular networks and may be cheaper than using your own SIM card.
eSIMs are another option. Download a digital plan to your phone and use Japanese mobile networks right away. But you’ll need an eSIM-compatible phone that’s not locked to a specific network.
Offline Maps
Navigating Japan for the first time might seem tough for even a seasoned traveler like myself. Luckily, Japanese locals tend to be friendly and can help you find your way. But using a navigation app with offline maps makes wandering Japan easier.
Downloading offline maps saves you the hassle of finding and maintaining a stable internet connection. You can follow offline maps wherever you are, even in rural areas.
Translation Apps
A 2026 survey by the Japan Tourism Agency revealed that around 11% of visitors from abroad struggled to read signs. While many signs may be multilingual, some are in Japanese only.
To get around the language problem, travelers often use a translation app on their smartphone. Popular translation apps, including Google Translate, let you use your phone camera to decipher signs on the go.
Photo and Document Backups
Make sure you’re backing up all your photos to the cloud during your trip to Japan. I always double-check my backup settings before I jet off on another adventure, and I have thousands of vacation pics to cherish.
Backing up your photos to the cloud will sync your device pictures with your online account (for example, Google Photos). As long as you have an internet connection, your photos will back up automatically. But it’s best to check every day to make sure everything’s syncing right.
If you plan to carry any documents (like hotel bookings) digitally instead of physically, back them up before you travel. Creating cloud backups of documents can be a big help if anything happens to your device.
App and Website Restriction Checks
Not every website and app you use at home will be available in Japan. Some may be blocked due to copyright or legal reasons.
Love watching anime on Crunchroll? Sorry, that’s blocked in Japan because of local anime licensing rules. Before you travel to Japan, check whether the websites and apps you use often are available. Otherwise, you might need to use a VPN to access them, or you can try to find alternatives offering similar features and functions.
All Ready for Your Trip?
I love Japan, and I’m pretty sure you will, too. Take the time to digitally prepare for your vacation, though. You don’t want to get to Japan and realize you have no idea how to translate signs or access blocked apps.
When your devices are loaded up, you can focus on enjoying one of the most amazing countries in the world.
