Postcards are fun. I try to send out a dozen or so whenever I go on a trip. Since I am lazy I print out the addresses on labels and then I just have to stick them on the postcard and write a small note.

If you ever climb Mount Fuji, be sure to bring some postcards to send. There is a post office at the summit. There is also a large assortment of ink stamps to decorate the cards with at the post office.
