Artist Motoi Yamamoto was 24 when his little sister died of brain cancer. He began memorializing her through large-scale drawings made with salt.
In Japan, salt is closely tied to funeral rituals and mourning. In traditional funerals, mourners will throw it behind them as they enter the service. Before a match, sumo wrestlers often purify the ring with handfuls of the stuff, too. For Yamamoto, who grew up by the ocean, it was a medium that reflected his grief, as well as the fleetingness of life.
