I'm back in Tokyo for a short period for hanami, meeting up with old friends, having some excellent food and looking to bring stuff back home with me. One of the things I've missed were the konnyaku jellies that I think we used to get at Donki. Link goes to the ones in question.
I've searched around and however can't find any although I'm pretty sure they're still being made. Could any kind soul point me in the direction of maybe a supermarket chain or store that would carry these?
