What are the differences between Buddhist, Shinto, Christian, and Civil ceremonies?

Buddhist: A spiritual ceremony pledging marriage to Buddha and ancestors; focused on family and tradition.
Shinto: A traditional Japanese ceremony held at a shrine; formal and sacred in atmosphere.
Christian (Church-style): Romantic and emotional; perfect for dresses and popular among couples.
Civil (Jinzen-shiki): Flexible and personal; allows for creative and guest-inclusive ceremonies.
