The history of a transplanted culture is still evocatively fragrant in International District spots like the homespun Tsukushinbo. While sushi’s fine here—fish expertly sliced, rice perfectly seasoned, prices an unfailing bargain—the home-style Japanese fare is the reason to go. Chicken gizzard kushiyaki, rice vinegar–marinated smelt, whole grilled squid. Salty-sweet mozuku seaweed salad. Hearty bowls of curry rice. Crunchy fried pork cutlet with piquant sauce. Light, lacy golden fingers of tempura. And yes, the hand-lettered signboard is worth learning Japanese for. The interior hasn’t changed since Soichiro Honda invented the motorcycle. Beware the odd hours; don’t expect instant service.
