Safety Razor Day (Anzen Kamisori no Hi)

What Is Safety Razor Day?

December 2 is "Safety Razor Day." It commemorates December 2, 1901, when American inventor King C. Gillette was granted a patent for the "safety razor." Before that, straight razors — which required skilled honing and careful handling, and carried real risk — were the norm. Gillette's invention, a razor with a replaceable blade, was a revolutionary product that made safe, easy shaving accessible to everyone.

The Evolution of the Razor

• 1901: Gillette patents the safety razor with a replaceable-blade design
• 1960s: Disposable plastic razors emerge and become widely popular
• 1971: Gillette releases the "Trac II," the world's first twin-blade razor
• Today: Razors with five or six blades, vibration features, and skin-protective strips continue to push functionality forward

The Diversification of Shaving Styles

• Cartridge razors: Only the blade unit needs replacing — low upfront cost and convenient
• Electric shavers: Suitable for both wet and dry shaving, convenient for travel and business trips
• Single-blade and straight razors (a growing revival): The classic style, prized for a careful, close shave, has made a comeback as a "shaving hobby"
• Hair removal creams and depilation: Medical and salon-based hair removal has become popular as a more permanent solution
