tsuku

Tsuku, also known as Tsukumo or Tsukumo-gami, refers to an ancient Japanese belief and folklore concept surrounding objects that have reached their 100th year of existence. According to this belief, after a century, an object, whether it be a tool, clothing, or even a piece of furniture, develops a spirit or consciousness. These spirits are often depicted as minor deities or yokai, embodying the object's history and experiences.

The tsuku are not inherently malevolent, but their behavior can be influenced by their past treatment. An object well-cared for might develop a benevolent tsuku, bringing good fortune or assistance to its owner. Conversely, an object neglected or mistreated could harbor a resentful tsuku, leading to mischief or misfortune. These spirits are believed to reside within their respective objects, animating them and occasionally interacting with the human world.

The concept of tsuku highlights a deep respect for objects and their longevity within Japanese culture. It suggests a spiritual interconnectedness between humans and the material world, where even everyday items possess a form of life and history. While not a widespread belief in modern Japan, the idea of tsuku continues to be a fascinating element of Japanese folklore, often appearing in literature, art, and popular culture. It serves as a reminder of the passage of time and the stories embedded within the things we use.
