Products in Japanese convenience stores come and go at a bewildering velocity. One day you find the greatest canned coffee of all time and then, a week later, it’s gone forever.
The existence of these products is often so brief they almost completely fail to enter our collective memories or get tangled in the branches of the Internet.
We step into the local convenience store - or the one right across the street from that one - and select the latest and oddest products we can find.
The results aren't always pretty, but the write-ups are crucial for capturing the ephemeral nature of Japan’s consumer culture.
The remaining question is why Japanese companies spend so much time and money developing products that are likely to disappear within a few weeks.
