Stuff like Chocolate crunch, and Uji Kintoki Kakigori (lol) (TN- Kakigori is shaved ice, and Ujikintoki is a specific kind with shaved ice on the bottom and green tea syrup/red bean paste on the top.)
I'm a fan of Azuki and Rum Rasin. Oh and Choco Monaka Jumbo. (TN- Monaka is a kind of sweet cake, though the ice cream version itself is closer to ice cream wafers.)
