Osaka is one of the safest cities in Japan. Geographically, it is protected from tsunamis because of its placement behind a group of smaller islands. Walking around the city I noticed no one locks their bikes up. They leave them unlocked next to the bus station all day and know no one will steal them because of the respect factor. It's amazing. I have never, ever left my camera laying around unattended, but here I didn't think twice about doing it.
We saw some young children getting on the subway and I thought they had lost their class. As I'm pointing out a large crowd of classmates to the 'lost' students, Kevin informs me they are on their way home from school. No big deal riding the subway by themselves so young.
