MURAMASA

We use special steel as the base material, which previously was rarely used for tablet tooling.
We successfully improved the rigidity of the tablet tooling, etc. through machining processes that take advantage of our unique heat treatment technology established through precision jig and tool manufacturing.

Our Passion Hidden in MURAMASA

By applying our extensive technology and experience accumulated through the manufacture of precision dies for the automotive industry since our founding, we have entered the tablet tooling manufacturing industry.
With the understanding that what is valued most is quality, we have established our "MURAMASA" label for our special tableting tools that are produced using our unique heat treatment technology.
As a steel expert, we are striving to make MURAMASA the new standard in tableting tools in the years to come.

Future of MURAMASA

The demand for tableting tools is very high, not only within Japan but also overseas.
Our goal is to demonstrate the world-class technology of Japan in the form of tableting tools from NANNO.
We envisage a future in which the MURAMASA products that bear the name of world famous Japanese swords are widely used in many parts of the world.
