It's mainly used for nouns, adjective stems, and verb stems. After centuries of development, there is a notable number of kanji used in modern Japanese which have a different meaning from hanzi used in modern Chinese. Japanese has much less simplified Chinese characters and people use less kanji in general. The Latin alphabet, rōmaji, is also often used in modern Japanese, especially for company names and logos, advertising, and when inputting Japanese into a computer. The Hindu-Arabic numerals are generally used for numbers, but traditional Sino-Japanese numerals are also very common. Shinto and Buddhism are the primary religions of Japan, though a secular Christmas is widespread, and minority Christian and Islamic communities exist. Shinto is an ethnic religion that focuses on ceremonies and rituals. In Shinto, followers believe that kami, a Shinto deity or spirit, are present throughout nature, including rocks, trees, and mountains. Humans can also be considered to possess a kami. One of the goals of Shinto is to maintain a connection between humans, nature, and kami. The religion developed in Japan prior to the sixth century CE, after which point followers built shrines to worship kami. Buddhism developed in India around the 6th and 4th centuries BCE and eventually spread through China and Korea. It arrived in Japan during the 6th century CE, where it was initially unpopular. Most Japanese people were unable to understand the difficult philosophical messages present in Buddhism, however they did have an appreciation for the religion's art, which is believed to have led to the religion growing more popular. Buddhism is concerned with the soul and life after dying. In the religion a person's status was unimportant, as every person would get sick, age, die, and eventually be reincarnated into a new life, a cycle called saṃsāra. The suffering people experienced during life was one way for people to gain a better future. The ultimate goal was to escape the cycle of death and rebirth by attaining true insight. The Japanese "national character" has been written about under the term "Nihonjinron", literally meaning "theories/discussions about the Japanese people" and referring to texts on matters that are normally the concerns of sociology, psychology, history, linguistics, and philosophy, but emphasizing the authors' assumptions or perceptions of Japanese exceptionalism; these are predominantly written in Japan by Japanese people, though noted examples have also been written by foreign residents, journalists and even scholars.
