Yamazaki did on online poll of flavors customers would like to see and cheese cake won. These sandwiches contain cheese cake flavored cream and spongecake. This is one event of many in celebration of 30 years of Yamazaki Lunch Packs. I actually had no idea how long this product line has been on the market. I would guess the production method has improved dramatically over that period of time. All products in this line are very processed, but also very neat, clean, cheap, convenient and reasonably good tasting. Very tempting when you are in a hurry to catch a train. ヤマザキ ランチパック
