Very, very nice! I can ask around at the import shops in the city. :D
Depends upon the quality of the water it comes from too, though- Japan has to deal with the southeast china sea, and now the Fukushima area too. It's the healthy salts that get the contamination in seawater. D:
Now.. if they have Nigari in packaging older than the Fuku event, we're singing good things about it... ^^
