About
Opened in 2024 on the second floor of 1610 20th Street NW in Dupont Circle, Ko Japanese Dining describes itself as a Japanese family-owned restaurant serving authentic, home-style Japanese fare. The menu spans the breadth of Japanese comfort cooking: karaage fried chicken, tempura, potato croquettes, katsudon, yakisoba, and matcha desserts. What most distinctly marks Ko as genuinely Japanese-rooted is its annual Osechi bento for New Year — an intricate, symbolically rich tradition of handmade celebratory dishes that only restaurants with authentic Japanese cultural connections typically offer. Reservations are accepted through the website; the dining room is small and welcoming.
