Up until now I used
Mapion for when I needed to look up directions in Japan. Google has recently come out with an interesting
alternative. Its cool because you can scroll the map in any direction with your furry friend, zoom in and out and view a satellite view of the area too. But whilst you can do the cool stuff with the scrolling and get an idea of what the surrounding areas of your destination look like, the maps are not detailed. Still worth playing around with though.
