A giant Game Boy sits abandoned deep in the mountains of Sanuki City, Kagawa Prefecture. Located beside a neglected countryside house, this unique landmark serves as a functioning mailbox, though local postal authorities confirm it is not an official Japan Post box.
The structure is a piece of gaming history: an official "Big Game Boy" demonstration kiosk distributed by Nintendo to retail stores in the 1980s and 1990s. The oversized external buttons were cosmetic; inside, a standard Game Boy was wired to a CRT TV to display gameplay to shoppers.
A local resident later acquired the empty plastic shell, gutting the screen to install a functional mail slot and a hand-painted Japanese postal symbol. A Japanese angler hunting for hidden fishing spots randomly discovered the weathered, sun-faded kiosk. He shared photos online without coordinates to protect the nostalgic artifact from potential vandalism.
