Waka poems were a popular art form in the Heian period, enough that the famous poet Fujiwara no Sadaie and Emperor Go-Toba sought to put together a selected collection of chosen verses.
my body burns like the seaweed 
drying on the shores of Matsuho
mientras mi cuerpo es acariciado
por las llamas que queman algas.
meu corpo queima
como algas secando na orla de Matsuho
