The "Aoyama Kohaze" offers a fit that can be experienced. Aoyama Kohaze addresses concerns such as "When wearing a kimono, I wear tabi, but I feel discomfort from the kohaze" and "I want a kohaze that can flexibly adapt to my body." When used, it raises the question of how desirable it is for the kohaze to fit the bare foot without the feeling of foreign objects to the extent that one forgets it is made of metal, while also being flexible. To resolve this, Aoyama Industrial Research Institute has wrapped a brass wire with grooves around the kohaze, enhancing its elasticity and springiness, increasing its deflection strength, and ensuring it fits the body's curves without causing discomfort.

Underhole nuts address concerns such as "screws becoming loose," "screws rusting," "water leaking through gaps between screws and nuts," and "wanting to tighten against glass surfaces without scratching them." Made from thermoplastic elastomer, a material that is a hybrid of rubber and resin, it utilizes the unique elasticity and recovery properties of this material. The female thread does not have a threaded groove. As the male thread is screwed in, a threaded groove appears in the nut along the male thread due to elastic deformation. For more details, please contact us or refer to the catalog.
