Tactile wear (or "tezure" in Japanese) is the phenomenon generated by the touch of the human hand and skin over a period of one to several hundreds of years. Tactile wear can be observed in objects of daily use, but particularly in statues of Buddha that are frequently touched by people. The phenomenon of tactile wear was not discussed in the recent tribology conference, though human hand and friction coefficients between various materials were measured and have been recently reported. However, to our knowledge, there has been no research on the wear phenomenon and friction coeffcient. Some examples of tactile wear on wood, metal, and stone are presented in this study. In the example of the 286-year-old Buddha statue (Pindola Bharadvaja in Sinsyu-Zenkoji), the wear volume of the nose is 15 cm^3, and the wear rate is of 10^<-8> (mm^2/N) order. In addition, we also describe a simple experiment that can verify tactile wear phenomenon.
