The seven-story tower with a glass exterior near Tokyo's trendy Omotesando district serves not just as a co-working space with computers and free Wi-Fi. There is also a pantry, a bar counter and a spacious lounge where you can drink freshly roasted coffee and beer on tap free of charge. There is even a room for meditation or prayer.

The building, dubbed the Iceberg, is the sixth flexible office location in Japan opened by New York-based co-working giant WeWork, which has more than 260,000 users around the world.

Since the 8-year-old startup entered the Japanese market in February, it has transformed the landscape of the real estate business, experts say.
