I went to a ramen place in Tokyo and to order ramen you had to insert money and place your order via this machine. This felt like going back to the early 90s but in a way that we are definitely not used to in western countries. It had a very retro futuristic vibe!
When I visit a new country I always take a look at what mildly iconic retro items it maintains that I don’t find back home, for example the KiHa 40 trains in rural Japan, or the old Citroen cars in France, or the BBC microcomputers in the UK, among others.
