In Japan, even the most ordinary tool can be seen as carrying a spirit. A kitchen knife is more than steel—it holds the memory of countless meals and the care of its owner. When its life ends, it is not simply thrown away, but honored with respect.

This tradition is known as Hocho Kuyō, the knife memorial service. It reflects the belief that cherished objects acquire a soul over time. By giving thanks to a worn-out knife, people express gratitude for the craftsmanship that created it and the devotion with which it was used.

Every year on November 8, Knife Day is celebrated across Japan. The date comes from a playful word association: “11” for ii (good) and “8” for ha (blade). In Sakai, Seki, Sanjo, and other knife-making towns, people bring their old knives to shrines, where they are respectfully laid to rest—not as waste, but as honored companions.

The knife memorial service is more than a ritual. It is a cultural lesson in treasuring objects, respecting artisans, and pausing to value what we use. To honor a knife is to honor the spirit of craftsmanship itself, ensuring that respect and gratitude are passed on to future generations.
