This is a variety I have tried and really liked - maybe not as an everyday item, but as an occasional treat. Tamaruya Wasabi KitKat is a collaboration between the famous wasabi seller based in Shizuoka and KitKat. These KitKat claims a harmonious flavor balance between wasabi and white chocolate ingredients. I frequently see these for sale in Tokaido Shinkansen (bullet train) stations. If you go to areas where wasabi is grown, they put it in everything - wasabi ice cream is surprisingly good. ネスレ キットカット 田丸屋本店 わさび
