Drive safely in Japan, guided in your own language

AT-Navi runs next to Google Maps and says out loud what Japanese roads expect you to already know.

Version 1.7 · Android 8.0+ · APK file, not Google Play

AT-Navi on a phone mounted in a car

You can read the map. The road is the problem.

The wrong lane, found out too late

You realise you should be one lane over when the turn is already 100 metres away.

Signs you must obey before you can translate them

止まれ, 一方通行, 踏切, 徐行 — understanding them costs a second you do not have.

A limit that changed without you noticing

Most speeding tickets in Japan are not given to people driving fast on purpose.

What it says out loud

Everything is audio. You never need to look at the screen.

Lane guidance, 800 metres early

A full stop, not a slow roll

Railway crossings

Wrong way on a one-way street

When the limit changes

Google Maps keeps the wheel

Set it up once, then forget it

No buttons to press while driving.
