Transport & maps in Japan

Transport apps that work

• GO (taxi), S.RIDE, DiDi Japan — you need live data to book, track and pay. Usage: ~10–15 MB per trip.
• If you momentarily lose data, many drivers will pick you up if you send your location via WhatsApp.

Maps

• Google Maps, Apple Maps, Yahoo! Japan Maps: uses ~5–10 MB/hr for navigation. The initial map load consumes more.
• Offline: download the area on hotel Wi-Fi. Google Maps: tap your photo → Offline Maps → Select an area. Requires 100–300 MB storage.
• Maps.me / OsmAnd: lightweight alternatives that work 100% offline after downloading.

How to use less data on the go

• Plan routes on Wi-Fi and save them as favourites or offline.
• Lower satellite map quality (use street view only).
• Close background apps that drain data (Instagram, app updates).

Quick checklist: stay online without surprises

The make-or-break moment is often the first 30 minutes after landing: maps, transport, messages. Install your eSIM on Wi‑Fi before you travel and switch mobile data to the eSIM when you arrive. That way you're not dependent on airport Wi‑Fi and you avoid accidental roaming charges.

For typical use (maps + messaging + light social media), 1–3 GB per week is often enough. If you tether for a laptop, take video calls, or stream daily, aim for 10 GB+ or a plan with fair-use throttling instead of a hard cut-off.

• Networks: KDDI/au (5G), NTT docomo (4G), NTT docomo (5G), Rakuten Mobile (5G), SoftBank (5G)
• Offline maps: download the area in Google Maps, Apple Maps, Yahoo! Japan Maps while you're on hotel Wi‑Fi.
• On the move: GO (taxi), S.RIDE, DiDi Japan + LINE, WhatsApp work well on low data — video and app updates are usually the real data drains.
• Common weak spots: Deep mountain areas (Nikko and Hakone lake districts) · Remote islands (Yakushima, Iriomote in Okinawa)
• City context: Tokyo: Excellent coverage; Metro LTE on most lines; dense buildings can blip indoors. · Osaka: Strong 4G/5G; Dotonbori and Namba districts well-covered.

Phone setup tip: keep your primary SIM active for calls/SMS (so 2FA codes can arrive), but turn off mobile data on that line. Set the eSIM as your data line — it prevents accidental roaming on the wrong SIM and keeps WhatsApp/banking flows more predictable.
