Izakayas in Japan typically do not have strict time limits for how long you can stay and eat. However, some izakayas offer all-you-can-drink or all-you-can-eat options with specific time limits. During busy times, you might be asked to leave if there's a waiting list. Chain izakayas or those with unique policies may have their own rules. Larger groups may get more flexibility. It's a good idea to ask the staff for details when you arrive, especially if you have specific requirements or preferences.
