For an antidote to the history-drenched, temples-and-shrines ambience of Kyoto and Nara, step onboard a Shinkansen (high-speed train) and you will be in Osaka in less than half an hour. Traditionally the commercial centre of Japan, Osaka is a bustling city with lots of ultramodern neon-lit cityscapes and futuristic buildings. In the north is the business district of Umeda, with its many skyscrapers, while Namba in the south encompasses the city's main shopping and entertainment centres, including the famous area around Dōtonbori Bridge, where the streets are lined with hundreds of restaurants. A busy, lively city, Osaka is home to Japan's best aquarium, the Kaiyukan as well as the incredible open air Floating Garden Observatory on top of the Umeda Sky Building skyscrapers and the impressive Osaka Castle. With a wealth of excellent restaurants too, the city is considered to be the gourmet capital of Japan.
