Hagiwara writes in the preface: The author’s past life was that of a disconsolate iceberg that drifts and flows in the extreme regions of the northern seas. Looking at the phantom-like auroras from various spots of the iceberg, he yearned, suffered, rejoiced, sorrowed, at times getting angry with himself, as he wandered on vainly with the tides . Above his heart were always the disconsolate clouded skies of the extreme regions, the soul-ripping winds of the Iceland howling, screaming. He wrote all that painful life and the diary of a real person in these poems.
