METROPOLIS JAPAN - Aug 27 - While Tinder is still one of the most used dating apps in Japan (ranking 3rd in popularity), it doesn't address different cultural dating nuances. As an effect, it's generally used casually and without care. Dating in Japan is full of intricacies and unspoken rules that are difficult for a foreigner to wrap their head around. One of Japan's highest ranking apps, Pairs, reflects Japanese dating customs. Developed by Japanese startup Eureka, the app aims to slow the process down, contrary to Western apps. They encourage users to take their time and make informed decisions about potential dates. When creating a profile on Pairs, users are expected to answer a bombardment of what may seem like invasive questions, but are considered key factors in matchmaking in Japan - including their blood type or income.
