I see Japanese characters on the red lantern and the blue sign, which clearly points to Japan. The narrow, dense alleyway architecture with air conditioning units and specific utility meters is characteristic of older urban areas in Japan, likely Tokyo. The aesthetic of the small, cramped storefronts suggests a "yokocho" (alleyway) dining or drinking district. I am fairly confident this is in a major Japanese city.

Country: Japan
