The novel is a sweeping historical saga that follows four generations of a Korean family from the early 20th century to the 1980s, beginning in Japanese-occupied Korea and moving to Japan. It explores the family's struggles and triumphs against the backdrop of cultural and social discrimination. The game of Pachinko, a popular Japanese arcade game, serves as a metaphor for the randomness and challenges of life that the characters face, particularly in the context of their immigrant status and the enduring quest for identity, acceptance, and success in a foreign land. Through the family's experiences, the narrative delves into themes of love, sacrifice, ambition, and loyalty, painting a vivid portrait of an often invisible segment of Japanese society.
