Hokkaido takes place in an exclusive hospital in the snowy mountains of northern Japan. On the upper levels, its patients enjoy the amenities of a luxury resort. There’s an exquisitely maintained formal garden and a fine sushi restaurant. There are hot springs and its perfectly appointed rooms look out across a valley as lanterns drift by. Beneath lies its clinical underbelly where surgery is performed and the staff live, and where, in its bowels, a morgue sits.
