Fish waffles! Wonderful memories of a cart outside Kanda station, Tokyo. The authentic carts were even hard for me to find in Tokyo, but then some of the chain crepe places (very popular with Japanese teens) sell mini-fish waffles, in many novel varieties but the Thriller, the Absolute Killer is Fish Waffles filled with sweet potato! Once you get that, you don't want to settle for the red bean paste again.
I'll drive to southside of Gardena for a sweet potato fish waffle!
99 Ranch used to make these fresh (outside) with red bean paste but, haven't seen them in awhile. Have you tried in their "cookie" section. They may also have them frozen and you can put in the oven. Or Mitzuwa market?? It's a Japanese treat so, check places that sell Japanese products. :) KQ
