History Speedrun: Toyo Steel Co.
Toyo Steel Co., Ltd. was founded in Osaka in 1969, at a time when Japan’s postwar industrial sector was starting to reach a global audience for the first time. The company became known early on for developing a unique deep-drawing press technology that allowed them to manufacture the world’s first seamless steel toolbox from a single sheet of steel.
This deep-drawing press breakthrough not only simplified production but also created a stronger, cleaner design that helped to set Toyo apart from the more traditional riveted or welded tool boxes.
In Japan, Toyo became a dominant force in the steel toolbox market, achieving almost 70% of the domestic share. Its boxes were adopted by tradespeople, factories, and workshops – but the simple lines and colored powder-coated finishes gave them broad appeal well beyond industrial use – over time, Toyo toolboxes began appearing in homes, artist studios, and even as lifestyle accessories.
The company continues to produce all of its toolboxes in Osaka, Japan – and they still focus on longevity and a philosophy it memorably describes as “Dreams Will Not Rust.” More than half a century on, Toyo’s toolboxes remain undisputed icons of Japanese manufacturing.
The Toyo Steel Cantilever Toolbox
The Toyo Steel Cantilever Toolbox ST-350 is a pressed-steel tool case designed with a traditional cantilevered opening system to offer excellent access to the contents.
When the lid is lifted, the two upper trays swing out to reveal tiered compartments – giving the user a clear view of both small and large tools at once. This design eliminates the need to dig through a cluttered box, making it as practical for professional use as it is for home workshops or just for hobby storage.

Each of these toolboxes is made from a single sheet of steel using a deep-drawing press technique in order to avoid seams or weak points in its body. The result is a solid, rattle-free shell that resists damage under normal daily use. A powder-coated finish protects the steel from rust and scratches, and it has a secure center latch to keep it securely closed.
The ST-350 is now available to buy in the USA from the outfitting company Huckberry with free US shipping, free US returns, and a best price guarantee. If you’d like to read more or get your own you can visit the listing here.
