can any experts out there ? I think it supposes to mean Vietnam in Japanese. If anyone could help with a picture of it I'd be grateful.

there is kanji writing for every country in japanese, but i bet it's rarely used though, but here is betonamu

越南 it means something south ..

There is no Kanji for Betonamu. Japanese only write "Vietnam" in Katakana. It's ベトナム (Betonamu). Not 越南 (reading totally different from Betonamu). It is often used in Chinese, meaning Far South.

China (included Hong Kong and Taiwan) and North/South Korea are only written in Kanji on Japanese map, I believe.

EDIT: Japanese read 越南 as えつなん (etsunan). Chinese read same Kanji as yue(yueh)nan.

hey thanks for info guys
