These are digital camera print kiosks. For 50 yen a print, you get your images printed directly from your camera’s storage media–Compact Flash, Smart Media, Memory Stick, PC Card, even floppy.
These are at a big electronics store, but our local Family Mart convenience store has one, too. Ah, technology.
Personally, I like to work with my images before I print them–touching them up in Photoshop usually improves them. I print mine on photo paper with my ink jet printer. Not archival quality, but who archives birthday snapshots? Someday they’re going to be found in a box full of photos and somebody’s going to wonder ” Who are these people? Maybe Great-Aunt Kristen still remembers.”
