I have found some wrong information in your
website . In the map of your website, the name of the sea between Korea and
Japan is described as "Takeshima". It seems unreasonable to use the
name "Takeshima" which is decided in the period of imperialism
because its original name is "Dokdo" which has been used throughout
history. Therefore, I believe that the island located on the East, should be
called "Dokdo". Which is South Korea's territory.
This is a video about Dokdo. Please
reference this video for better understanding that Dokdo is South Korea's
territory.
