Hello, I’m Kim Kyoung Hoo in Hana Academy Seoul, the Republic of Korea.

Thank you for various information. However, while I was reading the article I found something wrong about ‘Sea of Japan.’

'Buoyweather' marked ‘Sea of Japan’ instead of ‘East Sea’. It’s wrong to mark only ‘Sea of Japan’. According to international organization, “If each two 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.” Since Korea and Japan haven’t discussed name’s simplification, ‘Sea of Japan’ has to be marked with ‘East Sea’.

Therefore, I humbly ask you to change ‘Sea of Japan’ into ‘East Sea’ or at least mark both names. Thank you for your help. I look forward to hearing from you.

Yours sincerely,

Kim Kyoung Hoo
