I found out that a map of yours have wrongly named the “East Sea” as the “Sea of Japan” The name of the sea between the Korean Peninsula and the Japanese archipel ago, currently named as the “Sea of Japan” in your article, should be corrected to the “East sea”. According to international organization, “If each of two or more countries use different name, international organization advises the name’s simplification, and if it can’t do, it has to use both names.” Nowadays, as many international organizations including U. N. agencies have corrected ‘Sea of Japan’ to ‘East sea’, and I’d truly appreciate if your website could join this trend.
