K5 Tokyo Hotel / Claesson Koivisto Rune

K5 Tokyo, housed in a converted 1920s bank building, sits beside the Tokyo Stock Exchange and connects the traditional Imperial Palace area with hip Eastern Tokyo. The Japanese word ‘Aimai’ guides K5 Tokyo’s concept. It means vague, obscure or ambiguous, which in Japanese is often used in a positive, poetic sense. (The term denotes the benefits of erasing borders.) K5 Tokyo’s functions intentionally intermingle: The library is the bar, while the coffee shop doubles as a lounge, which flows into a wine bar and restaurant.
