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.

Kodiak is one of seven communities and the main city on Kodiak Island, Kodiak Island Borough, in the U.S. state of Alaska. All commercial transportation between the entire island and the outside world goes through this city either via ferryboat or airline. The population was 6,130 as of the 2010 census. 2014 estimates put the population at 6,304.

Originally inhabited by Alutiiq natives for over 7,000 years, the city was settled in the 18th century by the subjects of the Russian crown and became the capital of Russian Alaska.

Harvesting of the area's sea otter pelts led to the near extinction of the animal in the following century and led to wars with and enslavement of the natives for over 150 years.

After the Alaska Purchase by the United States in 1867, Kodiak became a commercial fishing center which continues to be the mainstay of its economy. A lesser economic influence includes tourism, mainly by those seeking outdoor adventure trips. Salmon, halibut, the unique Kodiak bear, elk, Sitka deer (black tail), and mountain goats attract hunting tourists as well as fishermen to the Kodiak Archipelago. The Alaska Department of Fish and Game maintains an office in the city and a website to help hunters and fishermen obtain the proper permits and learn about the laws specific to the Kodiak area.

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.
