Will be Traveling to Japan soon, What should I bring back?

I will be having a trip with my family (and to visit some members of family) for a little over a week. Mainly from Tokyo to Kyoto, what do you recommend bringing back from Japan?

I was asked to buy souvenirs from Pharmacy Stores like Donki, but I really don't know what products/ snacks are must haves.

Any recommendations?
