No Tipping Policy (チップ不要 - Chippu fuyō)
Japan has a strict no-tipping policy across all service industries. High-quality service is expected and fully included in the bill; leaving extra money will confuse staff.
Rooted in 'Omotenashi' hospitality, providing outstanding service is viewed as a standard duty, not an extra performance that requires extra monetary rewards.
Pay exactly what is listed on the receipt. If you want to show deep appreciation, simply give a warm smile and say 'Gochisōsama deshita' (Thank you for the meal).
If you are deeply touched by outstanding service at a Japanese restaurant, what should you do about a tip?
