Les 20 meilleures applications japonaises indispensables pour les étrangers à Tokyo (2026)

The Best Apps for Foreigners in Japan: Your 2026 Essential List

Whether you just landed in Tokyo or you've been here a few months, having the right apps on your phone can make the difference between thriving and struggling. This guide covers the best apps for foreigners in Japan — 20 essential tools that cover everything from navigating the subway to paying your taxes, all tested and recommended by people who actually live here.

Japan's app ecosystem is unique. Many services have Japan-only apps that are far superior to their global counterparts. Others are entirely in Japanese but still worth using once you know how. Let's break it all down by category.

Navigation: Getting Around Tokyo Without Getting Lost

1. Yahoo! Transit (乗換案内)

This is the gold standard for train and bus navigation in Japan. Yahoo! Transit gives you real-time delay information, platform numbers, and fare breakdowns — details Google Maps often misses.

The app is primarily in Japanese, but the interface is intuitive enough to use after a short learning curve. Many long-term Tokyo residents swear by it over any English alternative.

2. Google Maps (Japan Mode)

Google Maps works well in Tokyo, especially after its Japan-specific transit updates in 2024. Use it for walking directions, restaurant discovery, and business hours. Combine it with Yahoo! Transit for the best of both worlds.

3. Navitime for Japan Travel

Navitime fills the gaps between Google Maps and Yahoo! Transit. It handles rural buses, highway buses, and tourist routes that other apps ignore. If you're planning a day trip to Nikko or Hakone, this is your go-to.

4. IC Card Apps (Suica / PASMO)

The Suica app (on iPhone with Face ID or Android) lets you load money and tap your phone to pay at train gates and convenience stores. No physical card needed. This alone eliminates so much daily friction — get it set up in your first week.

Translation & OCR: Reading Japan's World of Japanese Text

5. Google Lens

Built into Google Maps and the Google app, Lens lets you point your camera at any Japanese text and get an instant translation overlay. Perfect for menus, signs, and mail from your landlord.

6. DeepL

For longer documents — contracts, official letters, work emails — DeepL produces significantly more natural translations than Google Translate for Japanese. The free version handles most daily needs.

7. Yomiwa

Yomiwa specializes in Japanese OCR and kanji lookup. Point it at a character you don't recognize and it identifies it instantly, with stroke order and readings. Essential for Japanese learners.

8. papago

Naver's Papago handles Japanese-Korean-English translation with impressive nuance, especially for conversational Japanese. It's particularly useful for voice translation when talking to shopkeepers or building managers.

9. Japanese (by Renzo Inc.)

This dictionary app is the offline lifesaver. No internet? No problem. It contains 170,000+ entries and works without a data connection — useful for moments in rural areas or underground stations.

10. XTranslate (formerly imiwa?)

A comprehensive grammar-aware dictionary that explains not just word meanings but verb conjugations and grammar patterns. Serious learners will use this daily.

In Tokyo, your translation app isn't a crutch — it's a key. The right one unlocks everything from restaurant menus to apartment contracts.

Food Apps: Eating Well in Tokyo on Any Budget

11. Tabelog

Japan's equivalent of Yelp, but more trusted and more detailed. Tabelog's ratings are notoriously strict — a 3.5 is genuinely excellent. Use the English version of the website or the app with Google Lens to navigate reviews.

A Tabelog score above 3.8 is considered elite. This is the app locals use to vet restaurants before special occasions.

12. Uber Eats Japan

Uber Eats works exactly as you'd expect, with an English interface and wide coverage across Tokyo's 23 wards. Delivery fees are higher than in many countries (typically ¥150–¥490), but the restaurant selection is excellent.

13. Demae-can (出前館)

Japan's largest food delivery platform by restaurant count. Many local Japanese restaurants that aren't on Uber Eats are on Demae-can. The app is mostly in Japanese, but pairing it with Google Lens makes it manageable. Delivery fees are often lower than Uber Eats.

Banking & Payments: Managing Money as a Foreigner in Japan

14. PayPay

PayPay is Japan's dominant QR payment app with over 60 million users. Link it to a Japanese bank account or credit card and you can pay at convenience stores, restaurants, taxis, and even small mom-and-pop shops.

The app runs frequent cashback campaigns — sometimes 20% back at participating stores. It's one of the fastest ways to save money on daily spending without any effort.

15. Wise

Wise (formerly TransferWise) is the most cost-effective way to send money home or receive foreign income in Japan. The exchange rates are near mid-market, and fees are transparent. Many freelancers and remote workers in Tokyo use Wise as their primary international account.

16. Revolut

Revolut launched properly in Japan in 2020 and has been gaining traction among expats. It offers multi-currency accounts, instant exchange, and a physical card. Particularly useful if you're traveling frequently around Asia.

Government & Tax Apps: The Ones Nobody Warns You About

17. My Number Card Portal (マイナポータル)

Once you have your My Number card, the MyNa Portal app lets you check your registered information, apply for some municipal services, and link your health insurance records. The app added English support in 2024, making it significantly more accessible for foreigners.

You'll need to set this up eventually — might as well do it early.

18. e-Tax (国税電子申告)

Filing your Japanese income tax online is genuinely possible as a foreigner, and e-Tax is the official platform. You'll need your My Number card and a compatible card reader (or the smartphone NFC function) to file electronically. Filing opens in mid-February each year, with a March 15 deadline for most residents.

If your Japanese is limited, pair e-Tax with DeepL for the setup process. Many expat accountants also offer e-Tax filing support for around ¥10,000–¥30,000 if you'd rather not DIY it.

Daily Life Apps: The Ones That Make Tokyo Feel Like Home

19. LINE

LINE is Japan's de facto messaging platform. Your landlord uses it. Your coworkers use it. Your doctor's office may use it. WhatsApp simply doesn't have the same reach here — set up LINE in your first 48 hours and share your ID with everyone you meet.

LINE also has a useful built-in translation feature for chats, which helps enormously when communicating with Japanese contacts.

20. Mercari (メルカリ)

Japan's biggest second-hand marketplace is a game-changer for expats setting up an apartment. You can find furniture, kitchen appliances, bicycles, and electronics at 30–70% below retail prices. The in-app translation feature makes browsing surprisingly accessible even without Japanese.

When you eventually leave Japan, Mercari is also the best way to sell everything before your departure. Many sharehouses and furnished apartments attract guests who use Mercari to top up their space with personal touches without spending a fortune.

Bonus: Your Ward's Garbage App

Every Tokyo ward has its own garbage rules, and getting them wrong can cause real friction with neighbors. Most wards now have official apps or web tools (search "[your ward name] ごみ 分別") that tell you which day to put out which type of trash. Shibuya, Shinjuku, and Minato all have English-language guides available.

Living in a sharehouse often means garbage rules are explained during move-in, which is one of the underrated perks of that living style — no solo trial and error on your first morning.

Final Thoughts

Moving to Tokyo without these apps is like moving in without a key — technically possible, but unnecessarily hard. Install the navigation and payment apps in your first week, layer in the translation tools as you settle, and tackle the government apps once you have your My Number card sorted.

If you're still in the early stages of your Tokyo move — figuring out where to live, how to set up a bank account, and what daily life actually costs — Modern Living Tokyo's furnished apartments and sharehouses are designed to make that landing as smooth as possible. Many of our residents share tips like these in community LINE groups, so you're never figuring it out completely alone.

Tokyo is one of the most livable cities in the world. The right apps just help you experience that from day one.
