Osaka is the second largest metropolitan area in Japan and serves a major economic hub. Historically a merchant city, Osaka has also been known as the “Nation’s Kitchen”. With a population of 2.5 million, Osaka is Japan’s third largest and second most important city. It has been the economic powerhouse of the Kansai region for many centuries. The city’s west side has the main port as well as a tourist destination with attractions such as Kyocera Dome, Universal Studios Japan, Osaka aquarium, Minami, Osaka castle, Umeda sky building and the Tempozan Harbour Village. Osaka is known for its food, both in Japan and abroad. Author Michael Boothand food critic François Simon of Le Figaro have both suggested that Osaka is the food capital of the world. Osaka’s culinary prevalence is the result of a location that has provided access to high quality ingredients, a high population of merchants, and close proximity to the ocean and waterway trade. In recent years, Osaka has started to garner more attention from foreigners with the increased popularity of cooking and dining in popular culture. The National Museum of Art(NMAO) is a subterranean Japanese and international art museum, housing mainly collections from the post-war era and regularly welcoming temporary exhibitions. Osaka Science Museum is in a five storied building next to the National Museum of Art, with a planetarium and an OMNIMAX theatre. The Museum of Oriental Ceramics holds more than 2,000 pieces of ceramics, from China, Korea, Japan and Vietnam, featuring displays of some of their Korean celadon under natural light.
