content: Actually, it's Japan. The line below the massive print is mostly katakana, 四尺玉コラボレション千ム, and reads (as best I can tell) "Yon shakudama koraborashon sen-mu" or "Four-shakudama collaboration 1000m" A "shakudama" is a shell that's roughly 20cm wide. So this would be one that's 80cm wide or roughly 2.6 feet across. The 1000m refers to the size of the airburst. Meaning when that fucker goes off, it's an entire fucking kilometer wide. And being Japan instead of China, the nips took relevant safety precautions rather than just lighting a fuse and running away like the chinks would have. Not sure I wanna know how big the lift charge was on that sonofabitch though.
