Some of you may be living apart from your family or partner, right? For you, I recommend listening to “Blue Moon.” It’s the first winter song by the idol group NiziU.

Among their songs, ‘Koion to Amazora’ is probably familiar even to older listeners, as it has been used in Ito-Yokado commercials and on NHK’s Red and White Song Contest.

It’s a poignant ballad I’d recommend to people of all ages.
