These are all things I've eaten, all quite tasty, in fact. Well, except for the ice cream--it was ok, but not a brilliant idea. If you're wondering WHY, you can buy a soft-serve cone in "local flavors" at many places around Japan; vanilla and green tea are the standards, but I've seen (and tried) chestnut, purple sweet potato, and boiled egg, depicted below.
