Osaka Travel guide, Japan. Tourist Attractions and Locations. Vacation Packages. Osaka is a charming, relaxed city best known for its food, fun and nightlife with some history and culture peeking through Osaka is only a short shinkansen ride from Tokyo, but has a very different personality to Japan's capital city. Hop off the bullet train into an area of exciting nightlife, delicious food and straight-talking, friendly locals. Along with plenty of shopping and modern attractions, Osaka also has a historical side, the highlight of which is Osaka Castle. The castle is a great place to discover more about Japanese history and to wander the beautiful grounds, especially during cherry blossom season in April when the sakura blooms and the weather is often at its best. Veiled much with a commercial-centric city touch, you may as well start from picking up the lively intonation of Osaka dialect, heard from the people as you ride on the escalators standing on the right, instead of the left in Tokyo; then discovering the contrast of popular food to eastern Japan, as you look for places to lunch. The deeper you get inside, and at the end of your stay, it is not completely impossible that you may have compiled your own original list of reasons covering from history, culture, sports, to business.
