In Neo-Shintoism, rituals and ceremonies are considered to be an integral part of the practice. They serve as a way to connect with the divine and honor the kami (spirits) that are believed to reside in all things. These rituals and ceremonies are seen as a way to maintain harmony and balance in the world.

One of the main purposes of rituals and ceremonies in Neo-Shintoism is to express gratitude and reverence towards the kami. This is often done through offerings of food, drink, and other symbolic items. These offerings are seen as a way to show appreciation for the blessings and guidance provided by the kami.

Another important role of rituals and ceremonies in Neo-Shintoism is to purify oneself and the surrounding environment. This is done through various purification rituals, such as washing hands and mouth before entering a sacred space, or performing a ritual called misogi, which involves standing under a waterfall or pouring water over oneself to cleanse the spirit.

Rituals and ceremonies are also used to mark important life events, such as births, weddings, and funerals. These events are seen as significant moments in a person's life and are often celebrated with rituals and ceremonies to honor the kami and seek their blessings.

In addition to honoring the kami and maintaining balance, rituals and ceremonies in Neo-Shintoism also serve as a way to connect with one's ancestors. Ancestor veneration is an important aspect of Neo-Shintoism, and rituals and ceremonies are performed to honor and seek guidance from one's ancestors.

Overall, rituals and ceremonies play a vital role in Neo-Shintoism as they are seen as a way to connect with the divine, maintain harmony and balance, and honor one's ancestors. They are an important part of the spiritual practice and are believed to bring blessings and guidance from the kami.
