In Japan it is sold as nigari (にがり, derived from the Japanese word for "bitter"), a white powder produced from seawater after the sodium chloride has been removed, and the water evaporated.
No Xapón vendese como nigari ( término que se deriva da palabra xaponesa “amargo”), un po branco producido a partir da auga do mar despois de quitar o cloruro de sodio e ter evaporado a auga.
