Blues singer Marikofun finds inspiration in a unique place — Japan's ancient tomb mounds, known as kofun in Japanese.

She has visited more than 1,000 ancient tomb mounds across Japan over the past seven years — a dedication expressed in the line of one of her songs, "I was so desperate to see you."

In April, the musician, who will not reveal her real name or age, released her first album titled "Kofun de Kofun!" It's a bit of a pun as "kofun" also means "excited" as well as an "ancient tomb mound." Her album has won some fans among younger listeners.
