I don't know if it was futuristic, but Hong Kong and Tokyo in the 90s definitely fueled a lot of techno-optimism in other countries. Seeing all the cool new devices (VCDs, CDs, game systems, early mobile phones and email, recording devices, bullet trains, anime, etc.) come out and be adopted made it feel like really cool things were to come and bring exciting societal changes. A lot of people have strong nostalgia with that imagined future, but after the 2010 decade of smart phones and startups I think things look less exciting.
