Japanese internet celebrity Chunhun starts her day by listening to a band whose songs few other 20-something women in the nation are likely to have on their playlists: North Korea's all-female ensemble Moranbong Band.

"I listen to their songs for the same reason many Japanese women listen to K-pop or Taylor Swift," said freelance illustrator Chunhun, who does not publicly reveal her real name.

When her mornings feel particularly depressing, she opts for more bellicose music from north of the 38th parallel.
