Whether it be through natural elements of nature such as mountains, rivers, trees or even natural disasters, there are a variety of kami that exist almost everywhere and are associated with almost everything in society. There are a variety of Shinto shrines, each of which represent their own deities and spirits, and there are some Shinto shrines that are connected through networks such as the Inari Shrines. There are even some shrines that operate independently!
Shinto and the practices of Shinto continue in various aspects of Japanese society and communities because Shinto is simply an aspect of Japanese life. Shinto is deeply connected to the Japanese value system, the morality of human life and behaviors and the overall way in which Japanese people act and think. For example, while Shinto doesn't necessarily have a doctrine or set rules one must strictly follow, it does place an emphasis on a variety of values such as harmony with nature (和, Wa), sincerity and honesty (誠, Makoto), purity and impurity (清め, Kiyome/穢れ, Kegare), respect for traditions, respect for elders and ancestors, gratitude, community values and a variety of other unique values that influence Japanese social behaviors and cultural practices. People will often visit shrines or jinja to pay their respects to the the kami associated with that shrine, whether it be for good fortune, or on the occasion of one of the major holidays such as New Year or Setsubun.
