Dear webmaster,

Hello. This is Seonghyeon Sim, a high school student interested in geography from South Korea.

I have been using your published book (Battle at Sea 2011 edition, ISBN 978-0-7566-7491-5) and it helped me a lot on researching for a presentation related to naval warfare. 

However, I have found some minor points that may needed to be corrected during the research. In the map of your book, the name of the sea between Korea and Japan is described as "Sea of Japan". It seems unreasonable to use the name "Sea of Japan" which is decided in the period of imperialism because its original name is "East Sea" which has been used throughout history. Therefore, I believe that the body of water between Korea and Japan should be described as the “East Sea” or at least with the simultaneous use of both names; “East Sea/Sea of Japan.”

Also, if you do not mind, please let me know an e-mail address of the person in charge or another possible way to correction.

Thank you again for your help. I look forward to having a response.
