First, the name "Sea of Japan" was decided in the period of Japanese imperialism. In that period, Japan forcibly marked "East Sea" as "Sea of Japan". Therefore it seems unreasonable to use the name "Sea of Japan".

I humbly ask for your website to seriously consider the issue of changing the "Sea of Japan" to "East Sea" or at least, please name it both "East Sea" and "Sea of Japan".
