Are you interested in Asian history?
Do you know what Japan did in Asia in the past?
Japan invaded Korea, China, and other Southeast Asian countries.
And they all ran away with a chance to lose the Second World War.
Many Asian countries, especially Korea, which have experienced all these processes, are always cautious while interacting with Japan. Japan is now claim Dokdo, Japan's territory. This denies it is a globally recognized Korean territory.
Japan's calling them 'sea of japan', arguing that the sea in Japan a 'East Sea' in this way. Many people in the world know this fact
Korea is not making unreasonable claims now.
Japan is making a forced claim. You know this well and hope to reflect it on the map. I hope your good work - making maps - will prosper
