Sushisho Masa

When Masakatsu Oka decided he wanted to become a sushi chef, he knew there was something he needed to fix. Lacking neither passion nor commitment, it was in a sense his body that looked set to let him down.

“It’s because, truth be told, I’m left-handed,” confesses Oka, a trait that even today is considered undignified by some Japanese. Not wanting this perceived weakness to ruin his culinary ambitions, Oka could be found nightly practising cutting cabbage into thin strips with his right hand until, in his words, “I no longer feared the knife.”

It clearly worked. He moves the blade with swift, deft strokes, lightly scoring a slice of squid with dozens of fine, diagonal cuts. He angles his knife to the right, and repeats the action in the other direction to make a crisscross pattern so that when the flesh touches one’s tongue, it feels like it’s melting.

But Oka credits his skills less to his late-night cabbage training and more to his mentor, Keiji Nakazawa of Sushisho (p.XX). “Nakazawa-san is the person I respect most,” Oka says. “If I hadn’t met him, this restaurant wouldn’t exist.” Sushisho Masa, the name of Oka’s restaurant, is testament to that. The practice is known as noren-wake, or ‘dividing the noren’ – the noren being the curtain above the door that bears a restaurant’s name. By permitting him to use the Sushisho name, the mentor gives a public blessing to his acolyte’s new venture, indicating that the young man is equipped to safeguard his legacy.

An honour of that level must be earned, and Oka is no stranger to hard work. He says that losing his mother at an early age taught him to be independent. And that the punishing schedule of his early years learning the sushi trade – starting work at 7.30am, and ending around midnight – was a lesson in endurance. “Find out how far you can push yourself and then push even further,” he says, sounding more marathon runner than chef.

Indeed, as he works behind Sushisho Masa’s cosy seven-seat counter, Oka controls every movement and every breath. As the cuts of his knife create a staccato rhythm, his words meet the beat, becoming almost meditative as he describes each dish: aji (horse mackerel) is served with a dab of acidic hacchomiso, a deeply flavoured dark miso from Western Japan; rectangles of katsuo (bonito) come sandwiching paper-thin slices of garlic marinated in soy sauce to mellow the taste; and his decadent signature dish of three succulent slices of o-toro lightly layered with wasabi to create what he calls the ‘Masa-feuille’.

Oka’s eyes twinkle as he presents rare ingredients such as grilled anago liver, or octopus eggs simmered in dashi – all likely to surprise even the most dedicated lover of sushi. “I always keep my eyes open for new ideas. That’s what I try to teach my guys,” he says, gesturing towards his staff of three young apprentices. “I want them to become the kind of people who notice everything.” And just at that moment, he looks and sounds exactly like his mentor.
