Vancouver  is a coastal seaport city in western Canada, located in the Lower Mainland region of British Columbia. As the most populous city in the province, the 2016 census recorded 631,486 people in the city, up from 603,502 in 2011. The Greater Vancouver area had a population of 2,463,431 in 2016, making it the third-largest metropolitan area in Canada. Vancouver has the highest population density in Canada with over 5,400 people per square kilometre, which makes it the fifth-most densely populated city with over 250,000 residents in North America behind New York City, Guadalajara, San Francisco, and Mexico City according to the 2011 census. Vancouver is one of the most ethnically and linguistically diverse cities in Canada according to that census; 52% of its residents have a first language other than English.[8][9] Roughly 30% of the city's inhabitants are of Chineseheritage. Vancouver is classed as a Beta global city.

Vancouver is consistently named as one of the top five worldwide cities for livability and quality of life, and the Economist Intelligence Unit acknowledged it as the first city ranked among the top-ten of the world's most well-living cities for five consecutive years. Vancouver has hosted many international conferences and events, including the 1954 British Empire and Commonwealth Games, UN Habitat I, Expo 86, the World Police and Fire Games in 1989 and 2009; and the 2010 Winter Olympics and Paralympics which were held in Vancouver and Whistler, a resort community 125 km (78 mi) north of the city. In 2014, following thirty years in California, the TED conference made Vancouver its indefinite home. Several matches of the 2015 FIFA Women's World Cup were played in Vancouver, including the final at BC Place.

Ketchikan  is a city in the Ketchikan Gateway Borough, Alaska, United States, the southeasternmost city in Alaska. With a population at the 2010 census of 8,050, it is the fifth-most populous city in the state, and tenth-most populous community when census-designated places are included. The surrounding borough, encompassing suburbs both north and south of the city along the Tongass Highway (most of which are commonly regarded as a part of Ketchikan, albeit not a part of the city itself), plus small rural settlements accessible mostly by water, registered a population of 13,477 in that same census. Estimates put the 2017 population at 13,754 people. Incorporated on August 25, 1900, Ketchikan is the earliest extant incorporated city in Alaska, because consolidation or unification elsewhere in Alaska resulted in dissolution of those communities' city governments. Ketchikan is located on Revillagigedo Island, so named in 1793 by Captain George Vancouver.

Ketchikan is named after Ketchikan Creek, which flows through the town, emptying into the Tongass Narrows a short distance southeast of its downtown. "Ketchikan" comes from the Tlingit name for the creek, Kitschk-hin, the meaning of which is unclear. It may mean "the river belonging to Kitschk"; other accounts claim it means "Thundering Wings of an Eagle". In modern Tlingit this name is rendered as Kichx̱áan.

Tokyo, officially Tokyo Metropolis, one of the 47 prefectures of Japan, has served as the Japanese capital since 1869. As of 2014, the Greater Tokyo Arearanked as the most populous metropolitan area in the world. The urban area houses the seat of the Emperor of Japan, of the Japanese government and of the National Diet. Tokyo forms part of the Kantō region on the southeastern side of Japan's main island, Honshu, and includes the Izu Islands and Ogasawara Islands. Tokyo was formerly named Edo when Shōgun Tokugawa Ieyasu made the city his headquarters in 1603. It became the capital after Emperor Meiji moved his seat to the city from Kyoto in 1868; at that time Edo was renamed Tokyo. Tokyo Metropolis formed in 1943 from the merger of the former Tokyo Prefecture  and the city of Tokyo. Tokyo is often referred to as a city but is officially known and governed as a "metropolitan prefecture", which differs from and combines elements of a city and a prefecture, a characteristic unique to Tokyo.

The 23 Special Wards of Tokyo were formerly Tokyo City. On July 1, 1943, it merged with Tokyo Prefecture and became Tokyo Metropolis with an additional 26 municipalities in the western part of the prefecture, and the Izu islandsand Ogasawara islands south of Tokyo. The population of the special wards is over 9 million people, with the total population of Tokyo Metropolis exceeding 13.8 million. The prefecture is part of the world's most populous metropolitan area called the Greater Tokyo Area with over 38 million people and the world's largest urban agglomeration economy. As of 2011, Tokyo hosted 51 of the Fortune Global 500 companies, the highest number of any city in the world at that time. Tokyo ranked third (twice) in the International Financial Centres Development Index. The city is home to various television networks such as Fuji TV, Tokyo MX, TV Tokyo, TV Asahi, Nippon Television, NHK and the Tokyo Broadcasting System.
