One aspect of Japan that I never knew before I came here was that many people who live in houses have their names on the wall (or at least the mailbox) in front of their houses.
This is the name plate of one of our neighbour's.
This is ours. It's a lot cheaper than most that you see around. It also has our address on it, but I've edited that out.
Right next to it is our doorbell, which is also an intercom. I don't usually use the intercom as Japanese is hard enough when you've got visual cues, take that away and I'm really struggling. However the intercom has two access points inside the house (one upstairs and one down), we use it between floors, often to call children to meals.
All the houses are also numbered, but not in a linear way along a street like they are in many countries, the numbering seems to be random (although I'm sure it is not). In fact most streets don't have names. So our address consists of our suburb name, the number of our area of the suburb, the number of our block, and the house number: 1-19-10. Japanese addresses are also opposite to western addresses in that they start big and go small. So you start with Japan or with your city and the last number is your house number, unless you write the address in "English" or "Roman" letters and then the order is the same as what we're used to in Australia: smallest unit to largest unit.
Here's a post showing there are many different types of name plates.
