Our Origin

YAMAtune Performance Socks Origin

Founded by Ito Tsuneyuki as a knitwear manufacturer in the Nagoya region of Japan in 1963, ‘Yama Tsune’ initially began to produce women’s clothing items for use by many of the countries large corporations.

As the countries economy grew Yama Tsune recognised the demand for specific items such as socks and mittens, especially those of a durable and high quality construction.

Their ability to produce such items helped Yama Tsune grow rapidly.

By a process of continued development and by striving to meet the needs of their demanding customers, the brand was renamed in 2014 as YAMAtune.

A store on the Northern island of Hokkaido now showcases the companies products as well as displaying the same knitting machines that were used when the company started in 1963.

Ito Tsuneyuki still visits the store to this day to oil and maintain these machines.
