How are shintoism and Hinduism similar to eachother

Hinduism is also called the oldest religion, and some even claim it to have its origins beyond human life. The term “Hindu” referred to the people who lived on the other side of the Sindhu River. It has its history dating back to the Bronze Age of the Indus Valley Civilization.  Around 1.25 billion people throughout the world practice it, making it the third most practiced religion. Hinduism is a blend of diverse ideas on spirituality and traditions but has no underlying rules or orders.

Shintoism, on the other hand, is the indigenous religion of Japan. It revolves around the Kami (gods or spirits), who are supernatural entities believed to inhabit all things.  Shinto is primarily found in Japan, but its practitioners can be found in other countries too. Even though Shintoism is Japan’s largest religion, the exciting part is that most of the country’s population takes part in both Shinto and Buddhist activities.
