Question: Door into the Dark is a poetry collection by a man that received the Nobel Prize in Literature in what year?
Context: Tales of Heichū (Heichū monogatari) belongs to the genre of uta monogatari poem tales that emerged in Japanese literature from the mid 10th to the early 11th centuries.  As early as the "Collection of Ten-Thousand Leaves" ("Manyōshū"), a poetry collection completed around 759, there appeared poems introduced by brief prose narrations.  The imperial court began to come alive with poetry from around this time.  People exchanged poetry with one another on topics as diverse as love and politics and religion.  Towards the end of the 9th century it was common for individual poets to keep compilations of their own verse, sometimes explaining in prose the circumstances behind a poem's composition.  The highest honor was to have ones poem selected for inclusion in the "Collection of Ancient and Modern Poetry" (Kokinshū), the first imperial poetry collection, which was completed around 905.  By the middle of the 10th century the idea of a poem paired with a prose narration seems to have taken hold, and "Tales of Ise" (Ise monogatari), "Tales of Heichū", and "Tales of Yamato" (Yamato monogatari) seem to have emerged at about this same time.  Also, the second imperial poetry collection, "Collection of Later Poetry" (Gosenshū), commissioned in 951 and compiled shortly thereafter, has many narrative qualities.  The only extant manuscript of "Tales of Heichū" is a 61-page codex discovered in 1931 that seems to date from the Kamakura Period (1185–1333), some three hundred years after the work's probable date of composition.

The Nobel Prize in Physiology or Medicine (Swedish: "Nobelpriset i fysiologi eller medicin" ) is awarded annually by the Swedish Karolinska Institute to scientists and doctors in the various fields of physiology or medicine.  It is one of the five Nobel Prizes established by the 1895 will of Alfred Nobel (who died in 1896), awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine.  As dictated by Nobel's will, the award is administered by the Nobel Foundation and awarded by a committee that consists of five members and an executive secretary elected by the Karolinska Institute.  While commonly referred to as the Nobel Prize in Medicine, Nobel specifically stated that the prize be awarded for "physiology or medicine" in his will.  Because of this, the prize can be awarded in a broader range of fields.  The first Nobel Prize in Physiology or Medicine was awarded in 1901 to Emil Adolf von Behring, of Germany.  Each recipient receives a medal, a diploma and a monetary award that has varied throughout the years.  In 1901, von Behring received 150,782 SEK, which is equal to 7,731,004 SEK in December 2008.  In 2013, the prize was awarded to James E. Rothman, Randy W. Schekman and Thomas C. Südhof; they were recognised "after discovering how cells precisely transport material".  The award is presented in Stockholm at an annual ceremony on December 10, the anniversary of Nobel's death. Since 1901, the Nobel Prize in Literature (Swedish: "Nobelpriset i litteratur" ) has been awarded annually to an author from any country who has, in the words of the will of Alfred Nobel, produced "in the field of literature the most outstanding work in an ideal direction" (original Swedish: "den som inom litteraturen har producerat det mest framstående verket i en idealisk riktning").  Though individual works are sometimes cited as being particularly noteworthy, here "work" refers to an author's work as a whole.  The Swedish Academy decides who, if anyone, will receive the prize in any given year.  The academy announces the name of the chosen laureate in early October.  It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895; the others are the Nobel Prize in Chemistry, Nobel Prize in Physics, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine.
