Dear Webmaster,

Hello, this is Hyolee Seo who studies geography in South Korea.

I have found an error in one of your websites (https://guides.library.upenn.edu/alumni_travel_2020/Japan).

The sea between Korea and Japan is undoubtedly South Korea's territory, due to international laws and history. The sovereignty of South Korea over this sea, called "East Sea", is based on historic facts and firmly confirmed by "effective control", which is the main requirement of the establishment of territorial sovereignty in international laws. Could you correct the name of this sea as the "East Sea"?

Further, if you do not mind, could you let me know an e-mail address of the person in charge or another possible way to correct this, please?

Thank you for your help.

I will look forward to hearing from you.

Sincerely,

Hyolee Seo
