Absolute Tipping Ban (チップ不要のルール - Chippu nashi)
Tipping is absolutely not required or expected in Japanese taxis. Worshippers pay only the exact metered fare. Offering tips will confuse the driver and prompt them to run after you to return the extra money.
Rooted in the pride of Japanese service culture, where flawless hospitality ('Omotenashi') and professional driving are already fully covered by the official fare. Exceptional service is the default standard, not an extra.
Pay the exact amount shown on the taximeter. If you want to show extra gratitude without breaking customs, you can say: 'Otsuri wa totte oite kudasai' (Please keep the change) when receiving small coins back.
