This is an original song by Midori Hara (Japanese) in Sinhalese.
This song is written by Kapila Kumara Kalinga( Sri lankan ) and music by Ranjit Balasuriya (Sri Lankan).
I once had this Korean girl walk up to me in Colombo and speak in Sinhalese. It took me a minute or two to realise she was speaking in Sinhalese..
I'm told that quite a few Japanese can speak Sinhalese these days. In the video above Midori sings about her second home, Sri Lanka.
