I found some chains with the name “Rainbow” (Raduga\Радуга) but their design is different from what is in the picture, there is even a chain of construction stores with the same name. I think it's an exclusive store for South Korea from some Russian immigrant.
Revenge for the Wildberries or something.
Thanks for the search. They sell products from Russia and some bread.
Were they deported to central asia during WW2? I don't know exactly.
No. They call themselves Koryo-saram, they are descendants of those people who, fleeing Japanese colonization, sought asylum from the Russian Empire in the 19th century and Russia took them in. Sakhalin Koreans are a separate sub-ethnic group, Koryo-Saram. The picture, btw, is the richest woman in Russia, 22nd on the Russian rich list >>131801
Selling forbidden Russian LGBT propaganda judging by the store name.
