Meaning

Carrying out with resolve; going ahead (with a plan) despite difficulties or opposition.

A noun that also functions as a suru verb (決行する). Implies determination to proceed regardless of obstacles. Used for events or plans that go ahead despite bad weather (雨天決行 — rain or shine), opposition, or unfavourable conditions.
