Expert Notes

The Kusshi, meaning 'precious' or 'ultimate' in Japanese, is a Pacific oyster transformed through intensive tumbling. This unique process creates an unnaturally deep cup with pillowy, abundant meat that practically spills from the shell. The aggressive tumbling produces a remarkably clean, delicate flavor—more briny than a Kumamoto but similarly mild and approachable, with a subtle fruity finish that keeps it interesting.

What Experts Say

Across 10 sources, tasters describe this oyster as:

Unique notes: lettuce, pillowy, fruity, ivory opacity

"Still a rarity on East Coast menus, Kusshis are all the rage out West, due to their small size and ultra-clean flavor. The depth and pillowy softness inside make the Kusshi resemble a Kumamoto, but it's a plain-old Pacific that's been tumbled into bonsai form."

"Like butter. It had a lot of sea in the aroma, a deep cleft (as all Kusshis do), and a surprisingly white shell; other Kusshis I've had have been purple-black. Whatever the shell color, Kusshis are some of the most reliable oysters you'll find anywhere."

"Kusshi was the original tumbled oyster. It's tossed into a high-tech mechanical drum every week or two so it gets as smooth and curved as a golf ball. This also makes the meat full, firm, and mild."

"This oyster was clean and crisp, with notes of lettuce and cucumber. Some people don't like oysters that taste like veggies, but I think it's fantastic!"

"Decent salt content with a meaty chew and a bright and intense cucumber finish."

"Kusshis start off with an ocean-fresh taste of salinity, transition into sweetness, and then finish with a fruity cucumber flavor. The meat has an ivory opacity to it, the texture is creamy and plump."

History & Background

The Kusshi was the original tumbled oyster on the market, immediately recognizable for its smooth, polished, cornucopia-shaped shell. It pioneered the tide tumbling technique that has since been adopted by other oyster farms.

The name 'Kusshi' derives from the Japanese term for 'ultimate' or 'precious,' reflecting the exceptional quality and careful cultivation process. Still a rarity on East Coast menus, Kusshis are all the rage out West.
