Japan is a country where tradition meets the hyper-modern, the latter of which is apparent in its widespread use of technology. For tourists, knowing a few key tech trends won’t just make your journey easier — it’s fast becoming essential. It goes without saying that having reliable mobile data is crucial to utilize these technologies, in addition to basic functions like maps and social media. 

This is where the Holafly eSIM comes in. It makes staying connected seamless — with a few clicks before you depart, you can bypass the need for physical SIM cards, complex local plans and the risk of unexpected roaming charges. Holafly offers you unlimited data and reliable internet access the moment you land, letting you focus entirely on your travel experience instead of troubleshooting your connection.

Below are the five biggest technology trends every visitor to Japan should be aware of, for practical use and for travel inspiration.  

1. Holafly eSIM: The Essential Tool for Traveling Japan

For travelers, the most significant recent leap in technology is the widespread adoption of the eSIM (embedded SIM) — a digital SIM card that can be downloaded onto your phone, allowing you to activate a cellular plan without a physical card. This digital technology is a game-changer for staying connected instantly upon arrival. And Holafly eSIMs make the whole process seamless — no need to struggle with physical SIM cards and no roaming fees.

Why Holafly?

Unlimited data: Holafly eSIMs offer unlimited data in over 200+ destinations, so you never have to worry about running out of gigabytes while you’re on the go. This is a significant advantage over other providers with strict data caps.
No roaming charges: Holafly’s prepaid eSIM plans are a single, upfront cost, so there are no hidden fees or unexpected charges when you get home.
Simple and fast setup: The purchase and activation process is easy and can be done entirely online. To install your eSIM profile you can choose from 3 options: Scan the QR code, manual installation, or one-button install for iOS 17.4 or above. You can activate your eSIM by switching on data as soon as you land at your destination.
24/7 customer support: If you have any issues, Holafly offers round-the-clock support in multiple languages to help you.
Global coverage: Holafly offers coverage in over 200 destinations, making it a reliable international eSIM carrier for all your future travels. If you travel to multiple destinations, it offers 15+ regional eSIMs, and a global eSIM covering 110+ countries.

Before you travel, make sure to check the official list of compatible phones on the Holafly website.

2. Paperless Digital Entry and Airport Efficiency

Japan has aggressively digitized its entry process, turning what was once a paperwork-heavy formality into an app-driven experience. With the Holafly eSIM, you can connect immediately upon landing, making it easy to organize and access the necessary apps — no stress, no struggling.

The Japan eVISA: Travelers from visa-exempt countries (including the US, UK, EU, Canada, Australia, Singapore and others) can visit Japan for short-term tourism without a visa. However, travelers from countries that do require a visa — such as China, India and the Philippines — must apply in advance. For many of these nationalities, Japan now offers a fully online Japan eVISA system, meaning the entire application and approval process is completed digitally (no embassy visit required). At departure, travelers must display the official “Visa Issuance Notice” live on their mobile device; screenshots and printed PDFs are not accepted.
Visit Japan Web: Japan’s official digital entry portal. By registering Immigration and Customs information before departure, travelers receive a QR code that can be scanned at electronic terminals on arrival, significantly speeding up entry procedures. While not mandatory, Visit Japan Web is strongly recommended and widely used at major airports.

3. Cashless Payment and Transit

While Japan famously ran on cash for decades, major cities are now overwhelmingly cashless. With nationwide connectivity, the Holalfy eSIM ensures that you’ll never struggle with payments or have any awkward encounters where your mobile payment app doesn’t load. 

Below, the two main things to know about cashless payment in Japan:

Mobile IC Cards (Suica/PASMO): Suica and PASMO are rechargeable transit cards that work across trains, subways and buses, and are widely accepted at convenience stores, vending machines, taxis, coin lockers, and many shops. Both cards can now be added to Apple Wallet, letting you tap-and-go directly from your iPhone or Apple Watch. You can also recharge your card with an international credit card right on your device, eliminating the need for cash or ticket machines.
QR Code Compatibility: Homegrown QR payment apps like PayPay are everywhere. While getting a full account is difficult for short-term visitors, the good news is that many Japanese merchants have partnered to accept major international apps like Alipay and WeChat Pay. Look for a sticker that mentions these global services.

4. Instant Translation Apps: Breaking the Language Barrier

You no longer need a bulky phrasebook to communicate with locals; your smartphone is your best interpreter — and the Holalfly eSIM ensures that you’ll always be able to connect.

Camera Translation (The Menu Lifesaver): Apps like Google Translate and Naver Papago feature a camera mode that allows you to point your phone at any Japanese text — a menu, a street sign, a product label — and see a real-time translation overlaid on your screen.
Voice-to-Voice Conversation: For talking with hotel staff or asking for directions, translation apps now offer a conversation mode. They listen, instantly translate your spoken English into Japanese, and play it aloud, allowing for two-way conversation. VoiceTra, developed specifically for travelers by a Japanese institute, is often cited as a highly reliable option for common travel scenarios.

5. Experience-First Travel: New Digital Tools

Technology is moving past just booking and into curating richer, more personalized experiences. But traveling to remote areas can feel unmanageable without reliable internet connection — which makes the Holafly eSIM essential. 

Personalized Itineraries: Modern booking platforms and travel agencies are using data to offer highly customized tours. Expect to see options tailored to hyper-specific interests, such as anime pilgrimage tours, exclusive pottery workshops or deep dives into local sake breweries, moving away from generic, one-size-fits-all sightseeing.
Promoting “Under-Tourism”: To combat overcrowding in cities like Kyoto and Tokyo, the government is using digital tools to promote less-visited regions. Tourists are increasingly using apps and online guides to find authentic experiences and unique attractions in the country’s diverse, quieter prefectures.

By integrating these technological tools — from digital entry to mobile payments and instant translation — you’ll unlock a more efficient, less stressful and deeper travel experience across Japan.
