How to write the address

In Japanese, an address is written from the largest area to the smallest: prefecture, city, district and finally the block and house number. In Roman letters the order is reversed, following Western conventions.

1-2-3 is an example of the chōme, block and house number. Replace it and the name with the real ones.
