6 apps you need on your next trip — lessons from Japan

We celebrated Halloween in Tokyo. Dressed as ketchup, mustard, and a hotdog, we walked through the Kabukicho crossing in Shinjuku — one of the most vibrant nightlife districts in the world — surrounded by thousands of people in incredible costumes, neon lights, and an energy that simply does not exist anywhere else on the planet. It was surreal, thrilling, and completely unforgettable.

But behind that perfect photo, there is something that does not always get told: the logistics. Japan is an extraordinary destination — and also one of the most complex to navigate if you do not have the right tools. The language, the transportation system, the currency, dietary restrictions, schedules, reservations — everything requires preparation.

These were the 6 apps we used the most during that trip, and that now live permanently on our travel list.

1. Kirapp eSIM — our #1 essential

Everything else on this list depends on one single thing: having internet. And for that, Kirapp eSIM was the first thing we activated before boarding the plane.

From the moment we landed in Tokyo, we had data. No hunting for a SIM card shop at the airport, no depending on the hotel WiFi, no panic upon arriving in a new country without a connection. Just internet, working, from the very first step on Japanese soil.

Traveling with reliable data is not a luxury — it is the difference between enjoying your trip and spending it solving connectivity problems.

2. Google Maps — Japan without getting lost

Japan's transportation system is a masterpiece of engineering — and it can also feel like a maze if you do not know how to use it. Tokyo has one of the densest and most complex metro systems in the world, with multiple lines, different operators, and station names that are not always displayed in romanized script.

Google Maps was our constant guide: train routes, walking times, exact transfers, public transport options. We opened it dozens of times a day. Without internet — without Kirapp — this app would not have worked.

3. Google Translate — the language-barrier breaker

Japanese is a beautiful language. It is also completely inaccessible if you do not speak it. Menus, metro signs, notices in shops — much of everyday life in Japan does not come translated into English, let alone Spanish.

Google Translate let us read menus through the camera in real time, understand important signs, and have basic conversations with locals who did not speak English. More than once, it turned a confusing situation into a moment of genuine connection with someone from the area.

4. Find Me Gluten Free — eating out without the stress

Traveling with dietary restrictions adds an extra layer of planning to every meal. In Japan, where soy sauce — which contains gluten — appears in almost everything, this app was essential.

Find Me Gluten Free shows nearby options with reviews from other users that detail not just whether a restaurant has gluten-free choices, but how seriously they take cross-contamination. That distinction matters. Thanks to this app, we were able to enjoy fresh sushi in Tokyo with complete peace of mind — and on a trip like this, that is priceless.

5. Wise — payments and currencies without surprises

Japan is largely a cash society — something that surprises many travelers used to paying for everything by card. Wise allowed us to handle Japanese yen at fair exchange rates, make payments in multiple currencies, and avoid the excessive fees that traditional banks charge.

If your trip includes more than one country or long layovers, Wise makes managing money significantly easier. No confusing conversions, no hidden charges, no unpleasant surprises on your bank statement when you get home.

6. Wanderlog — for the traveler who needs everything figured out before boarding

Wanderlog is the planner's travel app. Day-by-day itineraries, saved places, bookings, notes, lists of must-see spots — all organized in one place and accessible without having to dig through a dozen open tabs.

For a trip as detail-heavy as Japan — where some restaurants require reservations weeks in advance and certain attractions have specific time windows — having the plan centralized made the difference between arriving prepared and arriving to improvise.

Technology in service of the journey

These 6 apps did not replace the experience of being in Japan — they enhanced it. They gave us more time to walk without fear of getting lost, eat without worry, communicate with locals, and save every moment to share with the people who could not come along.

Because that is also part of traveling today: being able to show the world — or simply your family — what you are living, at the exact moment you are living it. For that, you need to be connected. And for that, there is Kirapp eSIM.

Save this list for your next adventure. You are going to need it.
