This a cool promotional sleeping bag of e-kakinotane.com, a rice cracker manufacturer here in Japan. The small crescent-shaped senbei/rice crackers* make a perfect shape for a sleeping bag as shown below.
←Kaki-peanuts or “Kaki-pi” are a common snack in Japan. Kaki-pi are kaki-no-tane (柿の種) consist of small crescent-shaped senbei (soy-flavored rice crackers) and peanuts.
These tiny crackers are consumed with beer and are often offered as a bar snack. The name comes from the fact that the pieces of senbei look like the seeds of the persimmon, or kaki in Japanese. (Wikipedia) ↯
