Shinto involves the worshipping of "Kami", which are known as "nature spirits." The Kami represent objects in nature e.g. rocks, trees, plants and mountains. The sun and the moon play an important role in Shintoism. Kami are considered the spirits from the deceased ancestors from former clans e.g. The " Kamakura Clan." Many believe that ancestors who have died including well known dignitaries, such as the emperor, will become Kami in their afterlife, where they will return as spirits in the earth. Every person is believed to have Kami within.
Kami possess both good and evil qualities. They also possess harsh, mischievous and sweet personalities . The Kami represent how we should act as humans. It is believed that there is over 8 million deities. The Kami play an influential role in Shinto. Shinto shrines are places where the Japanese Shintoist can worship the Kami.
Shinto followers place most emphasis on life. They do not concern themselves with death and what happens afterwards. You could say that Shinto is agnostic towards reincarnation. They (Shintoist) don't condone nor approve of reincarnation. Shintoist are more inclined to make themselves and others happy. They celebrate harmony throughout their life in retrospect towards the Kami.
