The book can help you better appreciate Shintoism, Japan's ancient religion of importance of the everyday. Get to know the most important parts of Shinto celebrations and ceremonies; glimpse of Shinto shrines, lives, ordinances, and learn about the relationship between Shintoism, politics, and nationalism.
Pretty thorough overview of the basics of Shinto and various aspects. As the name suggests, it's simple and won't be any sort of deep dive if that's what you're looking for, but it's a good starting point! Short and sweet, I learned a little bit and that's what I wanted.
