This pictere is one of the Japanese instant foods called "cup-men".
Men means noodle.
This is a soba whicn is the Japanese traditional food made of buckwheat.
Cooking cup-men is very easy, only put boiling water into the cup and wait three minutes or a little more.
There are so many typs of "cup-men" in Japan for example soba, ramen, udon, miso-soup, buta-jiru(Japanese pork soup), harusame, etc and almost is delicious and easy cooking.
Maybe the first "cup-men" in Japan is CUP NOODLE by Nissin foods in 1971, I like curry noodle.
