As hair clippers became widely used, the term "バリカン" also spread, though its origin remained unclear for a long time. However, while compiling the Japanese Dictionary of Loanwords at Sanseidō Bookstore, linguist Kyōsuke Kindaichi discovered its origins. Through his research, he found that the second-generation owner of the barber shop Kitatoko, located in front of the main gate of Tokyo Imperial University, Keiki Funakoshi, had identified an engraving on the clippers' blades. The engraving bore the name of the French company Bariquand et Marre, a firm co-founded by Jules Bariquand and Charles Marre. It was confirmed that the company's name had gradually become the general term for hair clippers in Japan. Originally, "バリカン" explicitly referred to barbering tools, but over time, it has also come to denote general cutting devices, such as "芝生バリカン" (grass clippers) used for trimming lawns.
