An award-winning story of love, friendship, and the power of human connection.

Kohei Araki believes that a dictionary is a boat to carry us across the sea of words. But after thirty-seven years of creating dictionaries, it's time for him to retire and find his replacement.

He discovers a kindred spirit in Mitsuya Majime—a young, disheveled square peg with a penchant for collecting antiquarian books and a background in linguistics—whom he swipes from his company's sales department.

Along with an energetic, if reluctant, new recruit and an elder linguistics scholar, Majime is tasked with a career-defining accomplishment: completing The Great Passage, a comprehensive 2,900-page tome of the Japanese language. On his journey, Majime discovers friendship, romance, and an incredible dedication to his work, inspired by the words that connect us all.
