Mizuno Tanrenjo

A five-generation family forge that still makes katanas and kitchen knives in the same workshop. All production stays in Sakai. No mass-market range, no compromise on materials. Each blade is individually forged.

Mizuno Tanrenjo is the family forge in its purest form. Founded in 1872 by master blacksmith Torakichi Mizuno in Sakai, it is now in its fifth generation. The remarkable fact: they still forge katanas. Not for decoration or tourism, but real Japanese swords following traditional techniques. It is one of the few workshops in Japan maintaining this dual activity - kitchen blades and swords.

The lineage is impressive. Torakichi learned from smiths who inherited the sword-making tradition. His son Teizaburo established the current workshop, trained by the legendary Sakurai Masayuki and Morita Masamichi. Five generations later, knowledge still passes the old way, through direct apprenticeship.

Production is entirely based in Sakai. Knives follow the traditional divided process: forging, tempering, polishing, handle mounting. But unlike other Sakai brands that subcontract to different artisans, Mizuno Tanrenjo controls a larger share of the process in-house. This is a forge in the true sense, not an assembler.

Steels range from shirogami (white steel) to premium grades. Finishes are sober, no frills. A Mizuno Tanrenjo knife does not try to seduce through looks - it cuts, and it cuts remarkably well. The price is accordingly higher than Sakai Takayuki, but you pay for tighter artisanal control and a deeper forging history. For connoisseurs, this is one of the names that truly matter in Sakai.
