styles that reflect the Japanese culture. Japanese architecture has traditionally been typified by wooden structures, elevated slightly off the ground, with tiled or thatched roofs. Sliding doors (fusuma) were used in place of walls, allowing the internal configuration of a space to be customized for different occasions. People usually sat on cushions or otherwise on the floor, traditionally; chairs and high tables were not widely used until the 20th century. Since the 19th century, however, Japan has incorporated much of Western, modern, and post-modern architecture into construction and design. Japanese language Many Japantowns will exhibit the use of the Japanese language in signage existing on road signs and on buildings as Japanese is the official and primary language of Japan. Japanese has a lexically distinct pitch-accent system. Early Japanese is known largely on the basis of its state in the 8th century, when the three major works of Old Japanese were compiled. The earliest attestation of the Japanese language is in a Chinese document from 252 AD. Japanese is written with a combination of three scripts: hiragana, derived from the Chinese cursive script, katakana, derived as a shorthand from Chinese characters, and kanji, imported from China. 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 common. Locations Americas Japantowns were created because of the widespread immigration of Japanese to America in the Meiji period (1868–1912). At that time, many Japanese were poor and sought economic opportunities in the United States. Japanese immigrants initially settled in Western parts of the US and Canada. At one time, there were 43 different Japantowns in California, ranging from several square blocks of Little Tokyo in Los Angeles, to one in the small farming community of Marysville in Yuba County. Besides typical businesses, these communities usually had Japanese language schools for the immigrants' children, Japanese language newspapers, Buddhist and Christian churches, and sometimes Japanese hospitals. After the World War II internment of the Japanese, most of those communities declined significantly or disappeared altogether. There are currently four recognized Japantowns left in the United States, which are facing issues such as commercialization, reconstruction, gentrification and dwindling Japanese populations.
