I will throw in another Japanese song just because I like the language so much. There are too many but considering history and everything, I think Ukifune (娴垷), Floating Boat, by GO!GO!7188 will do nicely. It's inspired by the tale of Genji, a novel from the 11th and written by a woman. https://www.youtube.com/watch?v=5-N79Q-gsf4
I wrote more about it a while ago: https://quickandtastycooking.org.uk/articles/ukifune/
Via the Ryukyu islands we move on to Taiwan with NiNi performing Huyao in Hokkien https://www.youtube.com/watch?v=ZTz16rsM9hY
The Philippines are surprisingly close, and we have a song in Tagalog, Callalily's Magbalik https://www.youtube.com/watch?v=c5CGoGOFHFs (thanks to @Iuckyduck)
The Philippines were at one time contested by Spain and Portugal, which led to the Treaty of Tordesillas and then the Treaty of Zaragoza, but that's another story, just giving me a convenient excuse to return to the Iberian peninsula with Mecano's El blues del esclavo (The blues of the slave) https://www.youtube.com/watch?v=EN0wLDi8EQ8
and O Mar (The Sea) by Madredeus www.youtube.com/watch?v=oStG0OPfKmo
