All-You-Can-Drink Course (飲み放題 - Nomihōdai)
The legendary 'Nomihōdai' (All-You-Can-Drink) system available at most Japanese Izakayas. For a flat rate (usually around 1,500 to 2,500 yen), you can order unlimited drinks within a set time limit (typically 90 to 120 minutes).
Born to fuel large-scale company banquets without exceeding budgets. It simplifies the bill-splitting process ('Waribikan') dramatically, taking a massive administrative burden off the shoulders of the party organizer.
When ordering Nomihōdai, you must adhere to the 'Glass Exchange Rule' (Glasu Kōkan): you cannot order a new drink until your current glass is completely empty. Staff will notify you when it's time for the 'Last Order' call.
