Pay exactly what’s on the bill, no more. If you want to show appreciation for good service, saying so directly (a thank-you, a compliment to the chef) lands better than money.
A small number of high-end establishments or specific situations (like a ryokan’s nakai-san, the room attendant) have their own customary gratitude gestures, but as a general default across restaurants, bars, taxis, and hotels, tipping doesn’t apply and can create an awkward exchange if you try.
- Don’t leave cash on the table thinking it’ll be seen as a nice gesture — staff may chase you outside to return it, assuming you left it by mistake.
- This applies to taxi drivers and hotel staff too, not just restaurants — the norm is consistent across service industries.
