を限りに

を限りに is used to indicate that something ends completely at a specific point in time or on a particular occasion, and will not continue afterward. It marks a clear and final boundary, often for events, activities, roles, or systems. Once that point is reached, the action or state permanently stops. This grammar is commonly used in formal or written Japanese, such as announcements, news articles, and official statements. It is often associated with retirement, resignation, closure, or final events.
