Sushi-Ko
Thousand Oaks, CA
It has since closed.
The short answer
Sushi restaurant closed; single source's specific closure date is internally inconsistent (see notes).
What happened on the show
Akira had trained as a sushi chef in Japan and once starred behind the counter at Sushi-Ko before buying it, but the man Ramsay met in Thousand Oaks had checked out entirely, shut down on his wife, his kids, and his own restaurant. His suggested dish, a sushi pizza, Ramsay spat out as rancid, an affront to pizza and to Japanese cooking alike. The miso soup was a day old and salty, the sashimi salmon frozen, and a hair turned up in the green tower. Service exposed the rest: recycled and even dirty chopsticks, unrefrigerated mayonnaise, and a broken fridge Akira could not afford to fix yet still packed with vegetables and eggs. His wife Lisa grew meaner as the night wore on, and Ramsay had to shut her down and demand Akira simply say something, anything, in his own defense. He could not. Ramsay's read was blunt: a broken man behind the counter.
After the cameras left
Sushi-Ko is closed, and here too the one specific date on record, August 2009, falls before the May 2010 broadcast, the same implausible pattern seen elsewhere from that source, so no closure date is asserted rather than repeat a likely error. The 2200 East Thousand Oaks Boulevard address lost its sushi restaurant. A family business built around a chef who had gone silent was never going to hold together once the marriage did not.
