I was surprised to see something strange on your homepage. On your homepage, there is a map that shows the location of the Spanish stores in Spain. If you see Asia, part of the map, You are expressed 'Sea Of Japan' in the sea between Korea and Japan.
It is amazing the ocean as a 'East Sea' notation on a map on its Web site for Koreans to.
From this you know the exact name of this sea.
It is the 'East Sea'.
For what reason are you into by the 'Sea Of Japan' and 'East Sea' I don't know what to call it, but it's quite wrong. And this is the part that must be modified.
It does not fit your company's image to use these two names together. Perhaps the consumer will hesitate to purchase your product if they know this. This will affect your sales in the end.
