Honorific term for the outing or visit of a noble, shogun, or member of the imperial family. Used in historical or formal contexts; not for ordinary people.
Honorific for a visit, but more general and modern; can be used for respected persons or customers.
Etymology
Derived from the honorific prefix お- attached to the noun 成り (nari), the continuative form of 成る (naru, 'to become'), originally referring to the appearance or arrival of a high-ranking person.
