The first capsule hotel in the world, Capsule Inn Osaka (New Japan Umeda), opened in 1979 and has been enticing guests ever since. The capsule concept was the brainchild of Kisho Kurokawa. In 1972, he designed a residence called "capsule house K".
It was an early conceptualization of a revolutionary idea, which he later worked into a commercial version. And so, the world's first capsule hotel was born.
Sorry ladies, this accommodation is for men only. While many modern capsule hotels are co-ed, the original Capsule Inn Osaka – located in Japan – was intended for use by business people, and the tradition remains. So, men, you may wonder, what exactly is a capsule hotel?
