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.

The book explores the author's journey to understand and practice Zen Buddhism through the art of archery in Japan. As a Westerner in a profoundly different culture, he delves into the spiritual and philosophical aspects of Zen, learning that mastery of archery is not merely about hitting the target, but about merging the archer, the bow, the arrow, and the target in a fluid, effortless action that transcends physical and mental boundaries. Through his experiences, the author reveals how Zen emphasizes intuition, insight, and the unity of mind and body, offering profound lessons on discipline and focus that apply far beyond archery.
