In 2026, it remains highly unconventional and often confusing to tip in Japan. The Japanese culture of omotenashi (wholehearted hospitality) dictates that high-quality service is an integral part of the price you pay, and offering extra cash can sometimes be perceived as demeaning or as a suggestion that the staff is underpaid. In many standard restaurants or taxis, a tip will be politely refused or the server may even chase you down to return "forgotten" money. If you truly wish to express extra gratitude, the most respectful way is to provide a small, wrapped gift from your home country or to place money inside a clean envelope (shugi-bukuro) and hand it over with both hands. However, a simple and sincere "Arigato gozaimasu" remains the most appropriate and appreciated way to thank someone for their service without causing social awkwardness.
