Applying for a visa to South Korea, 3rd world country passport holder

 Need help.

Been here in Japan for 8 months, my current visa is Instructor visa valid for 1 year. I would like to get a visa to South Korea but it says here I need to have stayed in Japan for 2 years already before being able to apply for a visa. Is this true? Is the information from this link updated? https://overseas.mofa.go.kr/jp-ja/brd/m_1106/view.do?seq=758472&page=1 Is it possible to email the Korean embassy here in Japan?

Thank you guys for helping,
