JLPT N1 Shinkanzen Grammar Lesson 16: ～に至って・～に至っても・～始末だ (To the point of... / Eventually...)

Explanation: Shows that a situation progresses to an extreme point—or that even after reaching such a point, the expected response still does not occur.
✓ ～に至って: only after matters reach that usually unexpected, serious stage does someone realize something or take action.
✓ ～に至っても: even after matters have become that serious, there is still no action or change.

Explanation: Expresses surprise, shock, or a strong negative evaluation of the overall situation. A general condition is usually mentioned first, followed by the most extreme case to emphasize how bad or astonishing the situation is.

Explanation: Explains that an unfavorable state has continued for some time and eventually leads to a bad outcome.
✓ Often used with adverbs emphasizing the final result, such as ついに (finally), とうとう (at last), and ～まで (to the extent of).

Explanation: Indicates that a state continues unchanged in a way that is contrary to what would normally be expected—for example, something should be restored after use but is simply left as it is.
✓ Mainly used for undesirable situations and often conveys dissatisfaction, complaint, or inconvenience.
