Osaka has a really amazing looking castle. Unfortunately once you go inside the castle you realized that it's actually a modern steel and concrete building made to look like the original Osaka Castle. The inside if the castle is a museum and looks nothing like what the castle actually looked like on the inside, there's even elevators and escalators.
While in Osaka earlier this year, I came across this semi-outdoor bathroom near the Osaka Castle. From the front the bathroom building looked normal, but once inside you saw that there was no back wall to the bathroom.
Everybody has probably heard that the are lots of crazy vending machines in Japan. This is a pretty unique vending machine that i saw in a train station in Osaka. It serves hot hot food like hot dogs, fries, squid balls and other cooked food.
