Today I explored the centre of the city, in particular the area around Osaka train station.
The highlight was the Umeda Sky Building, which I have to say is an amazing piece of architecture that with it exposed escalators reminded me of the Lloyds building in London.
It is called the Sky Building because the two towers are linked at the top with a viewing area that displays an amazing 360 degree vista of the city. It also made me aware of how, with the exception of the bay area the whole city is surrounded by mountains.
As it got darker I had a look around the north side of the train station and saw the building from a different angle.
After getting back to the hostel I decided to have a stroll around the surrounding area and to my delight found the Hitachi tower in a very lit up and Japanese feeling area.
