A crucial boundary indicating the maximum extent or capacity that can be reached, beyond which further progress or endurance becomes unattainable.
The point at which something can no longer be sustained, representing the highest level of ability or tolerance that one can endure before experiencing failure or breakdown.
The demarcation that separates two states or conditions, illustrating the tension between what is permissible and what exceeds acceptable boundaries.
Example:
あらゆるものに限界がある。
The specific point at which a limit is reached, beyond which something cannot continue or function effectively.
The moment of maximum capacity or resilience before a failure or significant change occurs.
The boundary or level that marks the transition from a manageable state to one that is unsustainable or problematic.
A critical juncture where an entity or system experiences stress that may lead to collapse or transformation.
The defining interval that distinguishes between stable and unstable conditions in a given context.
The lowest amount or value that can be accurately detected or quantified in a measurement process, beyond which results may not be reliable or meaningful.
The point at which the precision or accuracy of a measurement becomes insufficient, making it difficult to draw valid conclusions based on the gathered data.
A threshold that indicates the minimum level at which a measuring instrument or method can consistently produce trustworthy results.
A community facing significant challenges in sustaining itself due to extreme depopulation and an aging population, often characterized by a majority of residents being elderly, typically over the age of 65.
A type of settlement that is struggling to maintain its social structure as a result of drastic declines in population and increasing elderly demographics, predominantly found in rural and mountainous areas.
A village where the demographic shift towards a largely senior population makes the viability of community life increasingly difficult, highlighting issues of social cohesion and support in areas affected by rural depopulation.
A locality marked by the absence of a younger population, leading to difficulties in communal activities and services, as most of its residents fall into the senior citizen age group, reflecting broader trends of urban migration and rural decline.
