Snack recommendations for 85yo gma from Nagasaki

Long shot here, but worth a try. I’m trying to put together a care package of snacks to send to my grandmother who grew up in Nagasaki in the 1940s. What are some classic snacks that I could surprise her with? I know she loves red bean desserts, but I’m hoping some of you might know of some other old school snacks that might bring a smile to her face!
