Dagashi bars, according to a Reuters article by Sophie Hardach, cater to the nostalgia of stressed out Tokyo adults who want to escape, if ever so briefly, back to the halcyon days of their youth.
Unless you’re from Japan, however, don’t get all excited about this and catch the next flight to Tokyo. The all-you-can-eat candy is not abba-zabas, pixie sticks, or sweet-tarts, but rather “Japanese childhood favorites like chewy soybean candy and pickled squid on a stick.”
Ugh. All-you-can-barf is more like it.
