About us

SIO is the pronunciation of salt in Japanese.
As of salt to be used in cooking, we would like to contribute our customers.
Even though it is inconspicuous, salt is indispensable to any dish.
It plays an important role to completely change the taste of cooking in its usage.
Like salt used for cooking, SIO also want to be with customers.
