| Google Maps | Navigation, offline maps | Free | ✅ Yes |

1. Google Maps — Your Primary Navigator
Google Maps is the single most important app for campervan travel in Japan. It provides:
- Turn-by-turn English navigation with real-time traffic
- ETC toll estimates for expressway routes
- Alternative route options showing toll-free routes vs expressway
- Michi-no-Eki and campground locations searchable by Japanese name
- Gas station finder with real-time pricing at some locations
Critical setup before your trip: Download the offline map for Kyushu (Settings → Offline Maps → Select Area → Download). This ensures navigation continues working in mountainous areas with weak signal, such as around Mount Aso, Takachiho, and the Kunisaki Peninsula.
Pro tip: Search for destinations using Japanese characters for best results. Copy-paste from this guide or use Google Translate to convert English names.
2. Google Translate — Read Any Sign
Japan's signage is overwhelmingly in Japanese, especially at campgrounds, supermarkets, and gas stations. Google Translate's camera function is transformative:
- Open Google Translate
- Set language to Japanese → English
- Tap the camera icon
- Point at Japanese text — it translates in real-time via augmented reality
Before your trip: Download the Japanese language pack (Translate → Settings → Offline Translation → Japanese). This enables camera translation without internet.
Most useful for:
- Campground and onsen rules (posted signs)
- Supermarket food labels (ingredients, expiration dates)
- Gas station instructions (self-service vs full-service)
- Road signs in rural areas without English
- Restaurant menus at local shops
3. Tabelog — Find Authentic Restaurants
Tabelog (食べログ) is Japan's #1 restaurant review site — trusted by locals far more than Google Reviews. Its rating system is famously strict:
| Tabelog Score | Quality | Google Equivalent |
|---|---|---|
| 3.0-3.2 | Average | 3.5-4.0 |
| 3.3-3.5 | Good | 4.0-4.3 |
| 3.5-3.8 | Excellent | 4.3-4.7 |
| 3.8+ | Outstanding | 4.8-5.0 |
Use Google Chrome's auto-translate to read reviews in English. Search by area (エリア) and cuisine type (ジャンル). Photos of actual dishes are uploaded by reviewers and give an accurate preview.
4. Weather Apps
tenki.jp
The Japan Meteorological Agency's public weather service. Provides the most accurate Japan-specific forecasts including:
- Hourly precipitation probability (critical for deciding whether to hike or drive)
- Typhoon tracking (routes, timing, and intensity)
- Volcanic alert levels (essential for Mount Aso visits)
- UV index and pollen count
Windy.com
Excellent visual weather mapping. The animated wind and rain maps let you see weather systems approaching in real-time — useful for planning driving days around incoming rain.
5. PayPay — Mobile Payment
PayPay is Japan's most widely used mobile payment app. Many small restaurants, Michi-no-Eki shops, and local stores that don't accept credit cards do accept PayPay. Setup requires a Japanese phone number (your rental SIM works) or linking an international credit card. Scan QR codes to pay — no cash needed.

Frequently Asked Questions
Will my phone GPS work in Japan?
Yes. GPS works everywhere without a SIM card or internet. However, you need internet for Google Maps to load map tiles and calculate routes in real-time. Download offline maps before your trip as a backup.
Can I use Apple Maps instead of Google Maps?
Apple Maps works in Japan but is generally less accurate than Google Maps for driving directions, especially in rural areas. Google Maps has better coverage of small roads, Michi-no-Eki, and campground locations. We recommend Google Maps as your primary navigation.
