Self-Service Cold Water (セルフのお水 - Self Water)
The standard self-service system for cold drinking water ('O-hei') at casual Japanese ramen shops. Diners grab their own cups and fill them from counter faucets or pitchers at their table.
Born from the ramen industry's strict dedication to cost-efficiency. By reducing front-of-house labor, shops can invest more in high-quality broth ingredients, passing the savings down to customers.
When you sit down, spot the stack of plastic cups near the counter or table. Pour your own water from the push-lever dispenser or the heavy pitcher. If the pitcher near your neighbor is empty, offering a refill is a nice gesture.
