Frontierland is one of the "themed lands" at the many Disneyland-style parks run by Disney around the world. Themed to the American frontier of the 19th century, Frontierlands are home to cowboys and pioneers, saloons, red rock buttes and gold rushes along with some influence from American history and North America in general. It is named Westernland at Tokyo Disneyland and Grizzly Gulch at Hong Kong Disneyland.

Tokyo Disneyland is a 115-acre (47 ha) theme park at the Tokyo Disney Resort in Urayasu, Chiba Prefecture, Japan, near Tokyo. Its main gate is directly adjacent to both Maihama Station and Tokyo Disneyland Station. It was the first Disney park to be built outside the United States and it opened on April 15, 1983. The park was constructed by WED Enterprises in the same style as Disneyland in California and Magic Kingdom in Florida. It is owned by The Oriental Land Company, which licenses intellectual property from The Walt Disney Company. Tokyo Disneyland and its companion park, Tokyo DisneySea, are the only Disney parks in the world not owned or operated by The Walt Disney Company in any capacity.
