Yup, it's me again, with my annual request for help ID-ing a coin I've detected. You always come thru... and quickly! Thanks, in advance, for any light you can shed.
Those are everyday coins here in Japan. The value is equivalent to about 10 cents, and for that money you can sometimes buy a type of kid's snack called "Umaibou" http://www.osmkj.com/u3.jpg
You're not too far off the mark Umaibou is a cylindrical snack that is hollow in the middle. I think it might be a kind of puffed corn, but I could be mistaken. Anyway, it comes in a wide range of flavors, including メンタイ味-- "Cod roe" flavor (although it's actually flavored with red pepper) コーンポタージュ味-- Cream of corn flavor チーズ味 Cheese flavor ピザ味 Pizza flavor テリヤキバーガー味 Teriyaki burger flavor サラミ味 Salami flavor やさいサラダ味 Garden salad flavor チキンカレー味 Chicken curry flavor とんかつソース味 Pork sauce flavor エビマヨネーズ味 Shrimp-mayonnaise flavor タコヤキ味-- Takoyaki octopus ball flavor チョコレート味 Chocolate flavor http://ja.wikipedia.org/wiki/ファイル:Umaibou.jpg
