Usually no. In Japan, tipping is generally not expected in restaurants, taxis, and most services.

Do You Tip in Japan? Restaurant, Taxi, Hotel Guide

Quick tipping guide for travelers

Restaurants: no tip in normal cases.
Taxis: no tip expected.
Hotels: usually no tip for routine service.
Traditional inns: small formal gestures may exist, but not required for most tourists.

If staff refuses extra cash, do not insist. A polite thank-you is culturally safer.

Being punctual, respectful, and organized is often more appreciated than tipping money.

Often it is unnecessary and can feel awkward, especially in regular dining and transport contexts.

Some private international guides may accept it, but it is still not a universal expectation.

A sincere thank-you and respectful behavior are usually enough.
