Is this OK in Japan?

Japanese etiquette, answered in one glance.

From onsen to chopsticks to trains, Japan has unwritten rules visitors are expected to know. Manner Navi turns them into simple ○ / × / △ cards — in your language, fully offline.

The Problem
Translation apps can't tell you the rules.
😬

You step into a hot spring.
Swimsuit on, or off?

A map shows you where. A translator reads the sign. But neither tells you how to behave — and in Japan, the unspoken rules are the part travelers worry about most. Manner Navi fills that last gap.

How It Works
3 taps. No Japanese required.

FAQ
Japanese manners, explained
Can I go into an onsen with tattoos?
It depends on the facility. Many traditional onsen still refuse guests with visible tattoos, while others allow them or provide cover stickers. Manner Navi marks this as a △ (check first) and tells you what to look for, so you can confirm before you go.
Is it true that you don't tip in Japan?
Yes. Tipping is not part of Japanese culture and can even cause confusion or offense in restaurants, taxis, and hotels. Manner Navi explains the no-tipping culture and what to do instead.
What chopstick manners should I avoid?
Avoid sticking chopsticks upright in rice, passing food chopstick-to-chopstick, and stabbing food. Manner Navi has a dedicated chopstick etiquette category with ○ / × cards for each common mistake.
Does Manner Navi work offline?
Yes. All 71 cards are bundled in the app, so it works completely offline with no internet connection. Perfect for travelers without a data plan or roaming.

Yes. Manner Navi Japan is completely free with no subscription, no ads, and no in-app purchases.

No. Manner Navi collects no data at all. It has no network connection, no tracking, no analytics, and no accounts. Your only setting — preferred language — is stored locally on your device.
