The article mentions it -

>> But Ju ci is more than a technique; like its close cousin, Kintsugi (the Japanese art of repairing broken ceramics using lacquer and gold), Ju ci embraces a profound philosophy: that of celebrating “beauty of the imperfect.”

And that philosophy is called "wabi-sabi" (which is a hella fun word to say):

"Japanese aesthetic philosophy finding beauty in imperfection, transience, and incompleteness. Rooted in Zen Buddhism, it appreciates the natural cycle of growth and decay, valuing authenticity, rustic simplicity, and the patina of age over modern perfection. It encourages accepting flaws, such as cracks in pottery or weathered surfaces, as part of an object’s unique story.
