"Tokyo doesn’t have as many boutique hotels as you might expect, but the ones it does have are exquisitely crafted and absolutely unique. K5, for example, takes a 1920s-vintage bank building in Nihonbashi Kabutochō — essentially Tokyo’s Wall Street — and, with the help of the Stockholm-based architecture firm Claesson Koivisto Rune, transforms it into a living tribute to contemporary Swedish design, and in the process illuminates some of the affinities between Swedish and Japanese aesthetics." - Tablet Hotels
