Sushi Daizen

Tucked under the train tracks in Yurakucho, Sushi Daizen operates an intimate space with just 9 counter seats. Rather than leaning on staples like tuna, the kitchen distinguishes itself by spotlighting silver-skinned fish, mackerel chief among them. An omakase meal typically begins with small appetisers and comparative tastings of mackerel sashimi sourced from various regions and prepared with different cures, transitioning thoughtfully into meticulously crafted nigiri.

Mackerel sashimi is a clear focal point, letting diners discern subtle differences in fattiness and vinegar cures, alongside preparations such as richly seasoned sesame mackerel. Between raw courses, guests choose from several grilled fish options—including blackthroat seaperch—broiled to aromatic perfection. Additions like horse mackerel nigiri garnished with aromatics and seared mackerel hand rolls bring satisfying balance to the progression.

Another defining hallmark of the restaurant is its strict bring-your-own-beverage policy. No drinks are sold on the premises, yet the counter provides glasses, sake cups, ice, wine coolers, and water without any corkage fee, encouraging guests to arrive with favourite bottles of sake or wine in hand. Open only in the evenings, reservations are essential, rewarding those who plan ahead and select a special bottle of 1 to pair with an evening devoted to the subtleties of blue-backed fish.
