Sanjo

Sanjo is a city in Niigata Prefecture, Japan, known for its metalworking industry. It sits between two rivers in a flat region where residential neighborhoods and factory buildings stand side by side

Blacksmiths from Edo came here in the 17th century and taught locals how to make nails. The region shifted from a farming area into a center of metalwork

Workshops line the streets with low buildings and rolling doors where sparks often fly from the forges inside. Knife smiths hold demonstrations and show visitors the techniques of tempering and sharpening

The city sits about two hours by high-speed train from Tokyo and makes a good day trip. Workshops open mostly on weekdays, and some offer tours by appointment

A festival in October opens workshops to the public and lets visitors watch kitchen knives and scissors being made. Craftsmen explain how they forge shapes and polish blades
