who had received one star in the Michelin Guide for five years.

Famous Japanese restaurant “Ginza Ishizuka” Chef Mr. Tadashi Ishizuka

“People often say farm-raised fish are greasy and watery but yellowtails of Hashiguchi Aquaculture are not. They are sweet, rich in flavor, odorless and melt in our mouth. I want to buy fine quality of yellowtails from people I trust.”

“Kasu pickles are originally firmed meat. I tried another yellowtail but Hashiguchi yellowtail has excellent tender meat. I have never seen such wonderful yellowtails.”
