i get them at any regular asian market. the best come from Japan, but as part of china's move towards domination..they have taken the spoor from japan strains and really flooded the market..good mushrooms. china grown, japanese product.
mine are from china. not so sure i can afford japanese mushrooms. i keep smaller portions in a dark cupboard stuffed into ziplock bags..i deep freeze the larger portion and pull from the stock as needed.
they last forever.
