Most oyster farms buy their seed. Ishinomaki grows it. Mangokuura, a sheltered inlet in the city, is one of the few waters in the world where seed oysters can be collected, and those grown there are shipped across Japan and on to France and the United States.1 Miyagi Prefecture, Japan's second-largest oyster producer, accounts for more than half of the country's seed oysters.2

Catching the Seed

About fifty scallop shells are threaded onto a rope. In July, when oysters spawn, the ropes go into the sea, and the drifting young settle on the shells. After about three months the weak ones are removed and the ropes are lowered again to grow on. Kanji Suenaga, whose company farms seed here, credits the deep, indented ria coast of Sanriku.1

2011

The tsunami of March 2011 reached twenty metres on this coast and sank the ground, so farmers had to rebuild their beds.2 The seed oysters of Mangokuura survived, which Suenaga's account calls a miracle.1 The wider story is told in the Sanriku profile and in how Japanese oysters saved French oyster farming.

Flavor Breakdown

First
Sweetness and a savory depth together. Our scores put both at four, with brine at three.
Then
A plump, full oyster with a long savory finish. In Japan it is as often grilled, fried or simmered as eaten raw.

What Makes Ishinomaki Unique

Oysters now growing in France and on the American west coast descend from seed like this. Ishinomaki is one of the places the Pacific oyster's world tour started.12

Eat it in Miyagi in winter. Raw with ponzu if you trust the season, grilled if you want to do as the locals do.

Should You Add Lemon?

No

Ponzu or nothing. Lemon alone is too sharp for a savory oyster.
