Osaka is one of the top three most important cities in Japan. And while it is a stylish and modern?city with more than 2.5 million inhabitants, there is no shortage of attractions, many of which are not too far removed from the local culture. There’s alot to do in the city — during the day you will not want to miss the Osaka Castle, a famous historical landmark, the?Shitennoji Temple?and the Grand Front Osaka, a modern city architecture with shops and restaurants. And at night, head to the energetic Club Quattro for dancing and live music, or the Blue Note for some smooth jazz.
