Reading the signs
You do not need to learn Japanese to get by — a translation app plus a handful of signage kanji you can recognize on sight covers almost every situation you will hit as a visitor.
THE SHORT VERSION
Install Google Translate and download the Japanese offline pack before you fly. Its camera mode overlays an English translation directly onto Japanese text — menus, signs, packaging — in real time, no data connection needed once the pack is downloaded. For a spoken conversation, its conversation mode listens and translates both directions out loud.
TRANSLATION APPS
| App | Best for | Works offline? |
|---|---|---|
| Google Translate | The default choice for almost everything | Yes (download the Japanese pack first) |
| Yomiwa | Handwritten or stylized kanji Google sometimes misreads | Yes |
Camera mode works offline once you download the Japanese language pack in Settings → Offline translation. Conversation mode is useful for a back-and-forth with a shop or restaurant staff member. Dedicated pocket translator devices exist but are rarely worth buying now that phone apps do the same job.
TRANSLATING A MENU
Point Google Translate’s camera mode at a paper menu for an instant overlay translation.
If the menu is only a photo on a tablet or a QR-code page, take a screenshot and run it through the app instead.
Look for a picture menu or plastic food models in the window as a fallback — point rather than read.

BEFORE YOU GO
Offline translation needs a downloaded language pack, not a live connection, but you will still want data for maps and everything else — see the Connectivity guide to sort that out before you land.
