The rainy-season white fish
Isaki is the chicken grunt, a white fish that peaks in early summer — specifically the tsuyu rainy season, when it fattens so reliably that the best fish are called mugiwara isaki, “barley-straw isaki,” for the ripening grain. Where most shiromi are lean, summer isaki carries genuine fat and savor: firm, clean, with a depth that wins people over.
Mind the bones
Isaki has a reputation for hard, sharp bones — Japanese lore only half-jokes that they can lodge in your throat. A careful itamae bones it meticulously, and the reward is one of summer’s finest nigiri, often with the skin lightly seared.
