Tipping in Japan
In general, Japan does not have a tipping culture and trying to tip someone like a taxi driver, waiter, or hairdresser would mostly likely cause confusion. However, there are some cases in which an extra small fee is added to your bill at a restaurant or bar:
Otoshi
At some izakayas/pubs, you will be served a small dish to start called otoshi. This isn't something you order, but is served to all guests and acts as a seating charge. This dish is added to your bill and generally costs around ¥200.
This is not like a basket of bread on your table in Europe where if you refuse it/don't eat it, they don't charge you. If you refuse the otoshi, its more like going to a restaurant in the US and refusing to tip.
Cover Charge
At some bars in Japan, there is a cover charge. This will be very clearly communicated when you first arrive and won't be added to your bill at the end with no explanation. Cover charges can be pretty high, especially in Tokyo and Kyoto, around ¥2,000 per person or higher, and sometimes this includes your first drink. It is totally fine to leave the bar if you go in and realize there is a cover charge - cover charges are common but there are plenty of great bars that do not charge a cover!
Service Charge
At some high end hotels and restaurants, especially in Tokyo, adding a 10% service charge is becoming more common. Again, this charge is clearly stated when you book, and will be added to your final bill.
Tipping Guides
For a private or small group guide who does a great job, a small (10% or so) tip would be appreciated but is definitely not expected. If you plan to give a cash tip to a guide, please put money in a small envelope! These envelopes are used in Japan whenever you're giving cash to someone (other than at a shop or restaurant), and these can be purchased at any convenience store or 100 yen store. In lieu of a cash tip, bringing a small snack/sweet from your local area to give to guides is also a nice option.
