Staten Island —

Staten Island may soon be as well known for its sushi as its pizza.

The number of Japanese restaurants in the borough have tripled in the last four years, by one observer’s estimate. And some of the new eateries, like the Fushimi Restaurant and Lounge, aren’t even Japanese owned.

“It’s really a big trend now,” Joey Tse, Fushimi’s Chinese owner, said of the sushi boom.
