The "How" may be hard to say. I imagine some people where worried about some transcendent questions and their spirituality and tried to find some answers. Shinto (literally, the way of the gods) is the native Japanese religion. It originated in prehistoric times and has long played an important role in Japanese society.
Shinto was not "started", like Christianity. It developed as the native primitive religion of the Japanese people thousands of years ago. It changed and developed and evolved just like all religions do. But there was no "founder" of Shinto like there is in Buddhism, Confucianism, Christianity, and even Judaism and Islam. There's really no answer for "why" Shinto started, other than to meet the spiritual demands of the early aboriginal Japanese people. Unlike many other religions, Shinto has no founder, no sacred text, no developed religious philosophy , or specific moral code. The word "Shinto" did not come into use until the Japanese needed a term to distinguish their traditional religious practices from Buddhism and Confucianism, which came to Japan via cultural diffusion from mainland China and Korea. Nature purity and tranquility are stressed in the beliefs and practices of Shinto. Shinto (which is often still regarded as the state religion of Japan), and Buddhism, are the major religions. Christianity (mostly Catholic), accound for less than 2% of the Japanese population.
